[Q] Lost USB connection with CM10 Nightlies Updates - Nook Color Q&A, Help & Troubleshooting

While my original NC is running quite well with the CM10 nightlies, I have lost my ability to use the USB cable as my file transfer source since leaving CM 7.2.
I now do all of my files transfers directly to the SD card by removing it and accessing it directly via my computer.
I get the following when the cable is connected: "USB device not recognized".
I have tried both Media Device and Mass Storage settings to no avail.
This was not an issue with CM 7.2.
Seems to be the only real issue I am experiencing since I was able, with forum help, to redo my inadvertently updated NetFlicks.
Thanks in advance for any suggestions.

First, don't call the ROM JZ054K, it is CM10. You confuse folks. The problem probably is you have USB debugging enabled. Go to settings, developer options and uncheck Android debugging.

Followed your suggestion and unchecked Android Debugging. Rebooted and then hooked up the USB/Recharge cable. Still have same result with the "USB device not recognized" being displayed by Win7/64 with both Media Device or Mass Storage being selected.
Any other paths to explore on this?
Utilized my ROM nomenclature based on "About tablet: Bulid Number" and will switch to CM10 if that is a confusing issue.

The device id and vendor id are different in the CM10 from CM7, you would need to edit the android_winusb.inf file to include them.

Are you sure it is still unchecked? Did you go back and look after rebooting. You should not have to reboot to turn it off. That device not recognized issue is it is looking for ADB drivers because the debugging box is checked.

Yes, went back and looked and it was still unchecked. Normally reboot when I make any changes but went back and redid your suggestion from scratch without rebooting with same result.

The only thing I can think of is to go device manager in Windows and uninstall any devices in portable devices, android phone and under USB controllers, any mass storage devices. Then unplug and replug it back in, assuring debugging is still of. You should now get messages that things are installing, hopefully automatically.

I'm having the same issue, was using the Dec 2 and now 3 nightly. when I get time tonight I will roll back to Dec 1 since I know it was working there. Win7/Win8 here fyi

Unsuccessful
Tried: "...and under USB controllers, any mass storage devices." This actually allowed WE to show "Nook Color" but when I clicked on it, there was nothing there. The unit did temporarily display a USB connection at that time also.
Again, this was not an issue under CM7.2.
Thanks for your ongoing assist!
Update: Okay tried every conceivable way of deleting some or all of USB drivers under DM and reinstalling. Even went into BIOS and turned down USB 3.0 to 2.0!
Again erratically got the Andoid USB screen temporarily a couple of times but could not maintain it.
Definitely getting a Windows "Code 43" error indicator.

If you are getting windows errors installing drivers you may want to look at this post. It is for the HD+ and trying to get ADB working, but there is some interesting stuff there about unsigned windows drivers that may apply to you.

Will do!
It was very frustrating seeing the Android USB screen fleetingly appear several times and not be able to nail it down. I even got the WE screens for both drives briefly at one point!
Any idea as to why the issue exists with CM10 and not CM7.2?

Followup
Went there (http://forum.xda-developers.com/showthread.php?p=34954992) ...did that. Did not work at first, but it did work (somewhat) after I went back in and deleted the three drivers. I was then able to connect and utlilize WE to probe and adjust both emmc and sdcard. Calibre recognized that it was connected but I could not transfer anything directly from it to the NC.
Thanks for all of the help with this. Since I am probably around eight weeks from purchasing my HD+, I will just use the SD card to manually transfer files.
Interesting issue nonetheless!

I plugged my nook into a couple different computers and it was like the computer didnt even recognize something was plugged into the computer, though it charged the nook fine.

Had same problem, I went to settings - storage - then the menu box top right (three dots) then choose USB computer connections.. For the most of the time I just leave mine on Mass Storage -- On the second - I just leave the stock file manager and install any others I use - stock is not a lot of overhead for me to bother removing...

Hero WILL NOT sync.

I've tried installing the HTC Sync software by itself. I've tried manually creating prog files(x86)\htc\drivers\vista64 whatever. I've tried restarting the phone, and the computer. I've tried different memory cards, different USB cables, different USB ports, it REFUSES to work.
Windows 7 will say "Installing/Installed USB Mass Storage Device," the phone shows up in devices/printers and device manager, but I can get no further, and I cannot access the memory card or the phone storage in any way shape or form.

To get into the SD Card, are you pulling down the "Window Shade" and selecting USB Connected > Mount
To Sync do the same thing and select HTC Sync?
I don't mean to point out the easy questions I just noticed the low post count and figured you may be new. This stuff isn't exactly automated.
Under your device manager, is your phone called "My HTC" under "Android USB Devices"?
You need to make sure that you right click your phone after connecting it, and update the drivers manually to the Vista x86 / x64 drivers.

You also might try an older version of HTC Sync. I had to use an older one on my work laptop before Windows 7 would properly recognize it. I'll find that version # when I get to work and let you know. I think it had a 4 in it, like maybe 2.0.4. The newer versions had issues with 7, not sure if they still do, but it's something to try.

^^ what he said.
Also, I checked, and the version I am using is HTC Sync 2.0.8 downloaded straight from HTC's sprint hero website.
I know I've read in the past though, that the USB drivers from 2.0.4 worked better or something like that, so I seem to remember installing that fully (choosing both sync and USB to install) and then uninstalling, keeping the drivers intact, and then installing 2.0.8 and NOT choosing usb driver.
Do some reading if 2.0.8 doesn't work for you, and maybe you'll retrace the steps I took.
Here is what I did to make it sync with HTC Sync 2.0.18:
1) Connect the HTC Hero and let Windows install the drivers
2) Go to Devices and Printers
3) Right Click 'Android' and go to the Hardware tab
4) Click the ADB Interface and then click Properties
5) Click update Drivers
6) Click Browse My Computer for Driver Manually
7) Click Let My Pick from a list of Device Drivers On My Computer
8) There should be two listed, click My HTC and hit Next
It should sync after that.

This was my problem. I wasn't pulling down the damn window shade and telling the phone to mount the stupid volume.

[Q] USB-PC Not working?

I'm running OTA 4.0.3 (Acer_AV041_A500_1.033.00_PA_CUS1) rooted with I don't know what tool, but rooted after upgrading to 4.0.3, and using one of the tools found here which was the latest (at the time of rooting). The tablet has an "A500 Root Tools" app which has options to enter APX mode amongst other things.
I'm unable to get my Acer to connect to my PC via USB. I tried using both a mini(?)-usb cable and an A-A cable. My acer makes no notification, and there's no visible, or audible, evidence that anything was connected. USB Debugging enabled and disabled makes no difference. The tablet shows absolutely no sign that anything was plugged in. Nothing in notifications, nothing in any file managers.
Likewise on both a Windows 7 PC, and a Windows Vista machine. No little sound saying I plugged something in. Nothing listed in device manager. Nothing anywhere. The Win7 machine has the Acer drivers installed, as it is the machine I used to root it a few months ago.
Is there some weird ICS toggle that I need to perform to get this working? I know my USB ports are working as I've plugged in USB sticks and it mounts them without issue.
At the end of the day, I'm just wanting to flash my bootloader so that I can install CWM and a custom ROM. If there's a way to do that without needing my PC connected, that would make me equally happy.

Reinstall the Acer Drivers and also the Google drivers from the android sdk if u have that installed, if not use the adb_fast.zip attached. For you to successfully flash the BL do not underestimate the importance of having the drivers correctly installed - its the cause of 90% of the problems folks have had - my advice is to keep Device Manager open the whole time so you can see what is or isn't installing - dont proceed with the flash until you are sure they are - else you'll be looking at a downgrade to HC to fix things
you can also use Acer Recovery Installer from the market to install a custom recovery
While I appreciate your help, my issue is not drivers - Windows isn't loading the wrong drivers, or no drivers at all. Windows is showing no sign at all, at all, in device manger, any where, that a tablet has been plugged in. Like wise, the tablet gives ZERO notifications on being plugged in to a PC. Nothing. No sounds. No notification. Nothing.
I was originally using the micro(?) usb slot, and it was not working. I assumed that USB slot was dead. So I went and bought a USB A-A cable - after testing the normal USB slot and established it works - and it, too, does absolutely nothing when plugging the device into a PC.
I've since tested with an Ubuntu 12.04 machine as well. dmesg lists nothing.

and the adb interface driver thats not showing in device manager?? and you have the acer drivers installed??
All the signs are pointing to no drivers, failing that its sounding like a hardware issue either yr tab or cable - can u try on another pc/laptop?
Tested it on a Win 7 Dell, on a Vista Dell, and on an Ubuntu 12.04 Compaq. None show any sign of the device being connected.
I know my *two* micro USB cords work as my Nooks (color and tablet) have no problem with them. I know the large USB slot works as I've plugged in a keyboard and a USB memory stick and both are immediately detected by android.
I've also done a factory reset on the tab. Problem persists, obviously.
I'm actually setting up stock Win7 on another laptop right now. When it's complete I'll install acer drivers and plug in the tablet. It will be the only USB device, let alone android, to ever be plugged in to it.

The tool you used to root it (icsRoot) also has an unroot tool, which you could have used...I have tried to unroot manually which wasnt easy as I had a pre-rooted rom and I had real trouble getting rid of superuser, but in your case it may be a bit different....Sorry can't give you much help in the unrooting ics dept. Maybe try flashing acer stock rom??? or starting a new thread??

are you trying to flash something or do you mean when you connect yr tab
windowz explorer doesnt show your int/ext storage??
more info needed, what rom and bootloader, what OS on yr pc can u try on a different one, try a different cable and usb port..
have you run the acer drivers setup.exe
did u install the android usb ones
have u opened a command prompt from the folder where adb.exe is and run "adb devices"...does a number show??
when u have device manager open and connect yr cable do you see the drivers install. If they are there then uninstall them, disconnect yr cable and clean boot and reconnect.
If they do not install then manually install by pointing them to the folder you extracted the zip to...for the acer ones, just point it to your c: drive
If windows trys to install them, stop the hardware wizard from searching windows update and manually install them yourself.
If you've tried to flash the bootloader and it hasnt completed for what ever reason - you can strike issues such as yours - again, uninstall, clean boot, reconnect, manual install

That's correct, a straight USB "A to A" won't work. Further, I discovered something else; not all micro-usb cables are created equally! I was using a cable that worked fine on my Thunderbolt phone, would not work at all on my A500. Turned out there's some enhancements to the pinouts on the newer micro-usb devices. So the lesson here is go with the cable that came with the device if at all possible.
Seriously though, give a different micro-usb cable a shot; they're pretty cheap around the interwebz.

Windows 7 won't recognize Kindle as USB Drive

Hi All,
First post here, please be gentle! I don't think this issue is related to Glazed directly, so I'm posting it in this forum.
I installed Glazed ICS ROM on my Kindle Fire a few weeks ago. Yesterday I upgraded it to to 7/6 release. Afterwards, I tried connecting it to my Windows 7 PC. The driver is installed properly it seems (it shows up in Device Manager w/ no errors). I click "Turn on USB Storage" - however, it never shows up as a drive.
When I run the KFU - it says
"ADB Status: Offline
Boot Status: Unkown"
Thoughts? What other info do you need to help this poor fella out?!
Thanks for your help!
Josepho1997 said:
Try uninstalling the drivers you installed when you rooted it.(Android Composite Interface or whatever its called) That worked for me.
Also enable USB Debugging or whatever its called.
After uninstalling the drivers, plug in your Kindle. In the status bar you should see a usb icon. Click on it and turn on USB Storage or whatever ICS calls it.

Only drivers I found associated with the Kindle in device manager was Android ADB Interface. Removed it, checked USB Debugging (Was already enabled) plugged in Kindle, still no USB drive
thoughts?
Some of the ICS ROMs don't have USB mounting enabled yet. Try mounting manually in TWRP, that's what I've done. Sucks I know, but it's something.

The problem is in the kernel. It's an issue that Hashcode has been working on for a while now. The best thing that most people have been suggesting is to use AirDroid or to mount using TWRP. AirDroid lets you connect through wifi without having to reboot in to recovery, which is always nice. It's also completely free in the Android Market.

[Q] Nook Color driver software not found

Please help but beware I am a totally noob so you may have to explain things like you would to a five year old.
I rooted my Nook Color (firmware 1.4.3) with instructions from a Youtube video. (CyanogenMod 7) It allows us to boot to CyanogenMod with the sd card OR by removing the sd card it boots normally into the Nook Color.
It worked great for me but I lent the Nook to my sister and when she connected it to her pc (Windows 7) it indicated that it could not find the driver software for the nook - there is now a "yellow !" in her device manager so we uninstalled that and rebooted with the Nook plugged in and turned on but it still indicated that it was unsuccessful. The two drives do appear in my computer (F & G) however if we click on either one of them it says to insert a disk.
We have tried booting without the sdcard in it - tried different ports on the pc (in fact she has another pc running Windows 7 & it does the same thing) - we also tried a different cable. Nothing has helped so far.
Please help. Thank you in advance.

I am assuming you want to connect to the PC to transfer some files back and forth rather than to connect ADB. If you don't know what ADB is, that means you were not wanting that.
To fix the issue, boot to CM7 and go to settings, applications, development and uncheck Android debugging. Then connect the cable to the PC (I always have to do it twice), and a screen on the nook will pop up saying "USB connected" with a "turn on USB connection" button. Touch that button and a confirmation box pops up. Click OK. You should now see the drives on the PC and they should work. If that first screen does not pop up after plugging in twice, open the notification area from the bottom of the screen and a notification that says "USB connected" should be there. Touch that and the pop up will open.
The issue was the debugging choice which is an advanced feature you probably did not want and Windows was looking for a driver to make it work.

You are spot on - i have no idea what "ADB" is and just want to be able to transfer files from the pc to the Nook Color. We will try as you suggest and let you know how it goes - THANK YOU for helping!
This worked PERFECTLY!!!!! Thank you leapinlar for your 'easy to understand' directions and providing us with the answer so quickly. We just couldn't be happier! Many many thanks!

Nexus 4 won't connect to PC.

Hello, i have a very weird problem. My nexus 4 cant connect to pc as mass storage device.. It worked fine like 4 days ago.. I dont know what happened or what else i can try.. Already tried: usb debugging on/off, factory reset, usb settings in storage menu, different usb port, NOTHING HELPED! There are another weird thing that i spoted is that it only charges through usb when i have nothing selected in storage>usb connections menu, as soon as i try to select mtp or camera it stops from charging and nothing happens. Same problem for AC charging it wont charge when theres mtp or camera selected, and only charges as USB... I'm confused.. Are there any ways to get it working again?
I'm having the same problem.. I've just installed Windows 7 64 bit but it sees my Nexus 4 like Unknown Device.. I uninstalling the drivers and re installing them using Nexus Root Toolkit but no result for now..:crying:
Do you have a ROM or anything installed? I know with PA its a problem at the moment at times. A little more info would be nice. I never had a problem with Windows 7. I'm on Windows 8 now and i had an issue at first with it not showing up at times. But it seems to be fine now.
Just go in
Settings,
Dev options (if you not have it go in phone informations and press many times in row the Build Number, this activate Dev options)
and Disable USB Debugging,
then reconnect your phone, and the computer will see it
USB debbuging isnt working. i have no ROMS, stock android 4.3. And yes, now im running WIN 8, previuosly had 7, the problem occured after installing 8 and trying to plug it in. Its not showing in my computer neither in device Manager. I doesnt make any difference with, or without it pluged in, the only difference is that it will start charging, but then again ONLY when i disable everyting in storage>usb connections.
bump
do you have a fast charge app installed? it sounds like it's an issue related to fast charging via USB. if it's enabled you can't access anything on the phone via usb, but i think that requires to at least be rooted.
I'm on last PA 3.99-Rc1 and I just found out that if I go in Setting-Memory the appilcation shutdown .-. Never had this issue before .-.

Nothing, just read that it's a issue with PA while using last Franco Kernel nightly XD I'm going back to windows vista 32bit, so I believe the problem connecting my nexus 4 won't be any more an issue (Going back to Vista because for daily use it worked perfectly and every thing worked fine with the drivers, Windows 7 it's better, but too many issues with drivers bla bla bla XD) :laugh:
I have always used the Windows Driver from the Google SDK (Google USB Driver- As of today, Revision 8) for my Windows 7 64 bit computer and have never had a problem. More importantly there is an Update Manager that comes with the SDK, that when you run, notifies you of newer Windows drivers as they are released. That way as Google issues newer OS builds or Windows issues a new OS, I know that not only my driver but my platform tools aka fastboot/adb/etc. (As of today, Revision 18.0.1) will always be compatible. The problem with these toolkits and driver downloads all over the place on these forums is that you have know idea how old the internals are. The other obvious thing to check is a bad or intermittently bad USB cable. Also make sure "MTP" is checked in Settings > Storage >Settings > USB computer connection.
Hey, I'm sorry if it's against etiquette digging up an old post, but this part worked for me:

Glad I could help. That setting isn't exactly the easiest thing to find.
Fix usb
Go to device manager in windows 7/8/8.1 . Connect your mobile with usb. You will see android device or adb right click on it, select properties, click uninstall driver. NOTE: When you click this a small popup will appear saying remove software driver, tick on it and click uninstall.. there you go ..it will reinstall drivers and your phone will be finally connected.
im having the same problem . My phone shows as Unknown Device on Device Manager. Tried other cables and usb ports. I can tell that the cables and ports are not the problem since my Nexus 7 can connect without problem. Tried usb debuggin on/off, MTP on/off, PTP. Still no luck. Already tried to reinstall drivers but still the same problem. Hoping this is not a hardware issue. I already tried factory reset and flashing other ROMs
