Hi i have a nexus 7 (2012) everything was working fine until android 5. The device was slow and almost unusable. Then the 5.0.2 update came out and guess what? I updated it and now my laptop wont recognize the device so i tried a different cable and nothing. I plugged the nexus 7 in my second computer and nothing not even the sound that means you plugged something in the usb port. So i went to my brothers house and tried his computer.... the same... nothing. We plugged his nexus 7 (2012) 5.0.2 wich is the exact same device as mine and it works so we thought that it was the usb connector on the device and we switched my connector with his....NOTHING happens. computer wont recognize the device, no sound, no pop-up, no ADB detection. Does anyone have the same problem or a solution on how to downgrade 5.0.2 back to 4.4 without usb cable?
Thank you
Did you tried out to start n7 into fastboot mode and recovery mode?
Is usb not available also there?
fastboot and recovery mode also has no USB. absolutely nothing happens. when i connect the device it charges but the lightning icon does not appear on the battery in the status bar. and its not the usb port on the N7 i changed it.
?????????????????
Same here
I have the same Problem - a N7 GSM with 5.0.2 and no communication via USB.
I have tried different computers with Win7 and Ubuntu14.10. As well as differnt cables. (And all combinations of that work with my HTC M7, by the way)
Under Linux, not even lsusb shows the device, or dmesg shows any connection to a usb device.
To be completly honest, I did not give much love to my N7, I have been using it hardly. But when I did, I have been flashing some differnt Roms and testing different bootloaders so this might be some kind of my fault.
i updated to 5,1 and still the same problem so i assume its hardware related. but i know it is not the USB connector because i tried it on my brothers N7. and it works
Mine is quirky, comp recognizes it and can order boot but sideload and push to device don't work. Its odd.

Hey guys,
Just recently, my PC and any other PC Ive tried for that matter will not recognize my Note 3. I had Windows 7 and it worked fine for months, then just the other day it came up on the bottom as USB Device Not Recognized, and no matter what I do it will not do so. Yesterday, I upgraded to Windows 8.1 and still the same result. I have installed Kies 3, uninstalled and resintalled Samsung drivers and still nothing. I am running a custom rom in the stock slot using Safestrap...is it possible that that might have messed up something? Even when the cord is plugged into the PC, the phone doesnt come up with anything notification that it's plugged in, but it does say it is charging. If any of you have any tips or something please help because I am at my wits end.
Thanks
Have you tried with another cord?
Computer doesn't see device... Device doesn't detect plug in... Sounds like a bad USB cord

Yes, actually I have and still nothing...forgot to mention that in the original post.
It's a strange problem which leads me to believe that something has gone wrong in the phone, or that I caused something to go wrong by flashing a rom or three, since it did work previously. Unfortunately, I'm at status: Custom, although my Knox is 0x0.

Yes, this shows as disabled. What should this be?
Can't help you solve your problem, but last night I had a hiccup where I plugged my (17 day old) N3 into my computer in a USB2 port and ... nothing at all. (As if it were electrically disconnected - no "unknown devices" showing)
Tried it in a different USB2 port, and ... nothing.
Tried in in a USB 3.0 port - same computer, same OEM cord - and everything was fine. As far as I knew, nothing had changed on either end of things, although the previous evening I had used a different OTG cable for a USB key with the phone, and I had also had a automatic update of the Samsung Push Service on the phone. Nothing had been plugged into the PC's usb ports since it's prior cold boot. (Win 7 x64 Pro).
This morning (both PC and phone have been rebooted), everything is back to normal - both on the phone and the PC. Both the USB2 and USB3 ports all seem fine.
Ugh. Makes me nervous - brand new hardware.
Boot into Odin mode THEN plug the device in, let windows find the drivers for it then once that's done, reboot the phone regularly and see if it works then. It appears to be an issue with most to ALL Samsung devices, but this worked for my wife's galaxy S3 when the computer wouldn't recognize it and the phone didn't detect a PC connection.

Did you fix this problem?
Thank you! Worked perfectly!
I have the same problem, do you have any solutions ? Thanks.
I too have been struggling with this problem. The is no USB symbol in the notifications area on my phone whether I plug into to my computer at work (Win7) or at home (Win7), using a usb3 cable or a usb2 cable. Its as if there was a setting on my phone that allows recognition when plugged into a computer that has been turned off.Is there such a setting? I would love some help on this as well. Thanks in advance! I am rooted with towel root and have had no problems until last week. When I look in the device manager on my computer it shows :
SAMSUNG Android Phone
SAMSUNG Android ADB interface
I tried uninstalling the above and then plugging my phone back in and it re-installs the same driver shown above.
For what it is worth here are the drivers for SAMSUNG Android ADB Interface:
c:\windows\system32\DRIVERS\winusbsys
c:\windows\system32\WdfCoinstaller01007.dll
c:\windows\system32\WinUSBCoinstaller.dll
Should I be using different drivers ? Thanks|!
please help!
any solution yet? i have same problem, no usb detection and camera wont work i want to flash stock rom whit odin but i cant get the computer to recognize my phone...
I was able to fix the usb recognition problem. i had to do a factory restore. I lost root but gained usb recognition AND the Over the Air update to 4.4.4 and patiently awaiting the update to 5.0 hopefully this month!
My AT&T sgh 1337 Galaxy s4 has been a great phone, it was Loki'd back before the bootloader lock OTA's hit and I've been running CM11's latest milestone releases.
Lately I have had issue with my USB jack. When I would plug it in, I would just get an Error code 43 Unknown Device in windows, no device detected in linux & mac. I tried 3 different USB cables. I cleaned out the USB jack, didn't help. I did notice the interior of the jack was a bit worn and torn. It charges fine.
I went ahead and ordered a new USB jack/microphone board, verified the new part is specific and exact to the sgh-1337 model and installed it.
Plugged into a charger and tested, charging works, ~1300 mah draw on a 1.4amp charger. Looks good.
Plugged into a PC and immediately got Error code 43 USB device unrecognized. Still doesn't work. I changed USB modes in Settings>Storage>menu and, nothing. I enabled and disabled USB debugging several times. I've tested my machine with all samsung & ADB drivers installed and fresh machines, nothing. (Windows made the USB connect/disconnect sound between switching modes every time)
I installed Drivedroid (very sweet app for hosting disk images over USB) and used its settings panel to change USB modes, every single USB mode reports error 43.
Booting up into Recovery and mounting USB mass storage mode, same thing Error 43.
Booting into Download mode: Error 43.
USB OTG cable with mouse plugged in: nothing.
Is it possible that the USB controller on my phone's main board died? I hope not, that's unfortunate. It'd be hard to find a bootloader-unlocked motherboard replacement.
I read that an HTC user had the exact same problem, he reflashed his bootloader image from SD card and BAM, usb came alive again. I don't think that'd be a possibility with a samsung device though... hmm. Bummer, anyone think they can help?
I appreciate you reading.
wow, sorry to here that--could be hardware, you did about everything you could do--
Here are Google links which I am sure you already looked into
https://www.google.com/?gws_rd=ssl#q=usb+code+error+43+fix
Wild ideas--wipe your internal, reformat external or boot without it
Odin the MDL tar back to stock, keeping same bootloader
Odin and upgrade to NC1 with new bootloader
Use wifi apps for transfers
Not much help I know--just throwing stuff out there--:good:
Good Luck
Worst case lots of new phones out this fall--
... and is no longer recognized when connected to a computer via USB, meaning I can't return to stock to get ready for the Lollipop OTA.
Got a rooted Nexus 4 running the latest PA beta.
What happens when connecting to PC:
- On two different Windows machines: systray popup saying "USB device not recognized. The last USB device you connected to this computer malfunctioned etc.". In device manager it says "Unknown USB device (device descriptor request failed)"
- On elementary OS, based on Ubuntu 12.04: nothing, besides charging.
No USB debugging connection notification on the Nexus 4 either when plugging in.
What I've tried (USB debugging enabled, all relevant drivers installed):
- Settings > Storage > USB computer connection > check Camera PTP (used to be required in order to get an RSA key prompt when connecting to a computer, now it does nothing)
- Flashing latest stable CM to see if PA was to blame. Made no difference.
- Uninstalling device through device manager in Windows and reconnecting. No effect. Driver update doesn't work either, finds nothing.
- Using Wugfresh's Nexus toolkit to see if that worked, but that obviously doesn't work either when the device isn't recognized, same with the Universal Nexus Linux Toolkit on Linux.
- Scouring the net for solutions and coming up with nothing
I have flashed factory images before on this phone without problems. Should I consider it a hardware failure by now, or is this a known issue with a fix?
Try a new wire, different usb port on computer, finally look into cleaning your charging port on the phone/replacing it.

Tried three different cables, every port on two laptops, no joy - my girlfriend's phone connects normally.
Wouldn't replace the charging port, then I'd just get a new phone since it's a 2 years old Nexus 4. If only there was a way to flash the factory image using only TWRP.

Flash this in twrp http://forum.xda-developers.com/showthread.php?p=47476426

Thanks jd1639, that seemed to be exactly what I was looking for -
- but then I had an extremely blonde moment and formatted everything in TWRP, wiping the ROM I was gonna flash in the process, on a device where USB file transfer doesn't work anymore
My phone is now a paper weight.
Have you tried the file manager in twrp yet? I've found it connects when nothing else will...
Ok so long story short, i have a nexus 7 2012 which a rooted and installed cyanogen mod.
I was using it as a car install and works perfect, i'm using an otg cable to mount usb sticks, triggering soft shutdown and powering the nexus etc. So usb seems to be working fine.
Basically i removed the tablet it to modify the bootloader to turn on automatically with ac power applied, if the battery runs out i have to manually power on with button, but now i'm running into a problem.
Ever since taking the tablet out and trying to connect over usb, none of my computers detect the tablet.
I've tried different operating systems, drivers, cables etc etc.
Also changed from mtp to ptp in storage and also turned on usb debugging mode. If i connect an otg cable the nexus see's the otg and i can mount usb's etc.
So i thought i might try recover the nexus back to factory, maybe there was an issue with the rom corrupted etc, I've downloaded the original 4.2.2 firmware which is currently installed.
Booted into recovery and tried re-installing the 4.2.2 zip, it keeps aborting. A guy in work tried to use sideloader and connect via adb. no luck.
I'm not very familiar with the android platform so i've no other ideas what to do and other idea's how to recover now.
The guy i work with mentioned using a usb jig, would that be the way to go or can anyone else suggest some else that might help.
Thanks
Before you updated when was the last time you connected your N7 to your computer?
When you connect your N7 to your computer does it act like it is charging? Have you tried more than one computer? I had a similar problem with mine last year & sent it in 3 times. Asus replaced both the USB port board & the main board on different occassions. I suspect your mainboard might be faulty.
Does adb see the device

I last connected the nexus to the laptop a few monts back to load some music onto it, didn't have a problem. It's only been connected to a computer maybe 3 times. once to root/rom it then another few times to load music etc.
I can't see why the usb board maybe faulty as i can read data from a usb key when the otg cable is connected.
It's a strange one. You could be right, i might try pick up a broken nexus and swap some parts. Usb board etc.

Yes adb is shown in device manager, but it's not recognizing the nexus, comes up with an error 10 , cannot start. etc etc

I am having this same problem on my (unrooted) HTC One after attempting to "convert" it from an AT&T to a Google Play Edition device with the procedure described here.
As part of the procedure, I attempted to flash the stock Google Play Edition ROM using fastboot commands, but I got an error message. The instructions say to just try the flash again, but the phone no longer connects properly via USB (error 10) while in bootloader mode. While in bootloader mode, the phone indicates there is some sort of problem (a line showing the OS version is highlighted in red), and attempting to enter recovery mode does nothing but display a phone with a big red X in it. The phone seems to operate fine and responds to ADB commands when the phone is fully booted, albeit with the old OS (not Google Play Edition) still in place.
Any Android device could theoretically get in this state. We're sort of "paralyzed", because everything we want to do to regain control of the bootloader and fix the situation seems to require issuing fastboot commands from a computer connected to the phone while it's in bootloader mode. Yet entering recovery mode or getting a computer to connect to it via USB no longer seems possible.
I wonder if there's another way to issue fastboot commands without relying on the USB connection to a computer?
Got myself a google LG Nexus 4.
Connecting via USB - 2 different cables, 2 computers, 3 different operating systems (archlinux, debian, windows vista ) - i get nothing (*).
the phone does not acknowledge that it is connected to a computer, but it charges ok.
the computers do not recognize the phone in any way, not even in dmesg (or device manager in windows).
i have tried changing options inside the phone (debugging on/off, mtp/ptp...), even a full factory reset, and going into recovery and wiping cache/dalvik cache. - nothing.
wiggling the cable and such does not help.
i even replaced the usb connector, no change whatsoever.
so something tells me that it is not a hardware problem.
the phone has been upgraded to android 5.0 (before i became the owner).
my endless searches show that nobody knows what's going on, it might be hardware fatigue, it might be related to the upgrade to 5.x, it might be a firmware problem...
any helpful pointers, including downgrading & softbricking the system would be helpful (i just want to install ubuntu phone onto it).
(*) my other android phone connects ok with both cables, to all machines and operating systems.
With the phone in fastboot or recovery mode, is it recognized?
The fact that the usb port has been changed could indicate a problem with the motherboard connector.
Go into device manager with your phone connected and uninstall the drivers. Then install "universal adb driver"(google it it's from Koush) with your phone NOT connected.

i tried adb, the device list is empty.
booting into recovery, replugging the usb cable, i still get nothing. it's like there's nothing to communicate to, both from the computer's and the phone's point of view.
i will have to play with fastboot (i gather it works only while the phone is booted into recovery?), but i doubt it'll change anything.

do you mean the connector from the usb port, that flat cable snap-on thingy (far right on this image)?
is it realistic to try to fix that?
PS:
meanwhile the battery drained completely and i had a "Red light of death" which i managed to fix like this. i think it will take a while to recharge properly.
Adb commands will work with the phone booted into the rom. Use fastboot commands with the phone in fastboot mode.
Yes, the flat part at the it her end of the USB cable is what connects to the motherboard and is not worth fixing if that is causing the charging problem.
With a red LED, just connect it to a 2.0 amp charger using the original charging cable and let it charge for a few hours.
thanks again.
next thing i realized that the volume rocker isn't working (anymore?).
so i can't boot into recovery.
i don't know how, but once i managed to get into recovery, but couldn't make any choices in there.
anyhow, that sort of cinches it: i'm done with this phone. project failed.
(nevermind, it was a cheap ebay shot)
ubuntu phone will have to wait.
