USB Fix - Win7 x64 - USB Device not Recognized

For those of you having a problem with Windows 7 recognizing your Vibrant ... here is how I fixed it on my system.
*Note: You do not need to load any special USB drivers for your phone to be recognized in Mass Storage mode in Windows 7.
*Warning: You follow these instructions at your own risk ... no screaming at me if you try it and something gets screwed up!
1) Navigate your way into the Device Manager / Universal Serial Bus Controller
2) Uninstall the device(s) "USB Root Hub" (My system had 2 listed)
3) You will lose mouse and keyboard control (because you just removed the USB Hubs)
4) Reset your PC and allow Windows to boot normally.
5) Go back to the device manager and wait for all of the "!" marks to go away as windows re-installs the USB Hubs and reinitializes all of your devices.
6) Make sure your Vibrant is in mass storage mode and has USB debugging OFF
7) Plug in your Vibrant via the USB cable and be amazed as windows recognizes your device and assigns the drive letters. After you select the mount option on your phone you will have normal access via windows explorer.
Hope this helps some of you out there !!!

Thanks. I am having this problem right now. I used to work. now all of the sudden it just stopped connecting. But i have a clarification questions. when you say remove the usb root hub, do you mean uninstall or disable?
Thanks.

I had the same problem after flashing JI6 via ODIN (after softbricking a la t-mobile ota), but I was able to fix it by enabling the prompt to ask what to do every time usb was connected, and then changing it back to treating it as mass storage. I read this suggestion in another forum (don't remember where) and it helped with mine.
I had no trouble before the update, it just started right after.

Sorry, I should have been more clear. It should say uninstall. You want to force windows to reinstall the devices.

I know this thread is old but if you change your view in device manager to view by connection you can find which root hub to uninstall and then re-install. This happened randomly when I was trying to update my epic and I didn't have to re-start because it was only the front ports root hub that was having the problem. Thanks for the help.

[Q] Samsung Galaxy 3 goes out of adb/mass storage connection occasionally

Hi All,
I have been facing problem of my galaxy 3 I5801 not getting connected through adb/mass storage etc. Following are the symptoms:
* Even if I set USB settings for "Ask on connection", on USB cable insertion, the popup does not come.
* While USB cable is plugged in, I am able to do any change in USB settings (means the USB status is not connected)
* Though debugging is enabled, ADB does not detect the device
* On host side, Device Manager, following drivers are listed.
- USB - Samsung Mobile USB device
- USB - Samsung USB Composite device
- Ports - Samsung Mobile Modem Diagnostic Serial Port
- Modems - Samsung Mobile Modem
- Modems - Samsung Mobile USB modem
* Kies recognizes as I5801, however, contacts etc. are not read from the device
MASTER CLEAR solves this and gets back the device to proper mode and everything works fine. Have done it twice successfully. Again after some time or after installing few apks, I am back to above state. I have installed following apps this time -
aCar, Advanced Task Manager, Facebook, Orkut, Ray Dialer, Skype, To Do List, Twitter and Maps (Brut).
I suspect Maps(Brut) installation, but I need this badly as it is the only turn-by-turn free navigation app that I can use in India and I like that very much. However, uninstalling this app did not recover back the USB.
Any suggestion on how to recover the USB connection by keeping all my apps installed?
Any particular app that is suspect here which I should avoid installing at all?
Any thoughts

Boot into recovery mode and select "wipe cache partition" .

Thanks. I saw few other tips which are in my trial list if the same thing happens next.
I.
1. Dial *#7284# to open PhoneUtil
2. In USB section, switch to Modem, and then switch back to PDA
3. Exit
II.
Boot into recovery mode and reboot again.
III.
Gsam101's suggestion (thanks for that) - Boot into recovery mode and select "wipe cache partition"
Need to see how to boot to recovery mode though. Little confused on the key combinations for Galaxy I5801.

Use Home+VolUp+VolDown+Power combo You can release all the buttons after initial logo. You'll see recovery screen with 'reboot to the system' or smth option, use it and you'll get your USB back.

Thanks......

I got into the same situation. Tried option 1 and USB is back
Thanks a lot guys.

Option 2 worked for me. Thank you.

Glad that it worked. But, option 1 worked for me all the time. Is it that option 1 did not work for you or you did not try that?

not recognised.. on pc..

Kogan Agora HDMI Smart TV Quad Core - Root Access

Hi,
So I have had a good experience with the Kogan Agora 7" a couple of years ago. I flashed a new ROM and my 6 year old still idolizes it. It's perfect for games and movies while traveling and cost bugger all.
I was considering getting my kids a console unit for games but came across the new Quad core HDMI Dongle. I though to myself there is the ticket, When traveling i could use it as a smart TV (plug and play is King) Or it may be possible to replace or augment my Media-portal HTPC system.
I bought one and on the face of it it appears to do all that I require from an Android device like web surfing, mail checking and video streaming fine, except when it came to installing the Playstation controller.
I needed Root access and it was a bit of a pain to get it done. BUT I found it!
I used RK3188_ROOT for CX-919 FW0715 MOD by Everal. found here.
1. Turn the device on
2. Make sure USB debugging is enabled
3. Connect the device to Win7
4. Start the file "TPSparkyRoot.bat" as admin
Enjoy.
So if anyone decides to purchase one of these to play with, you will be glad to know that it is a Rockchip RK188. Weather you think that hardware is good or not is irrelevant but it is useful to know as I tried many methods to gain root but once I had this bit of info it became easy.
Those infinity Pocket PC's may be the same although I can't be sure.
I managed to pair a sixaxis controller and am working on getting it running in a game. I will post if i have any more issues and or success.

Thanks for posting this info. However I'm not able to get this to work. My PC doesn't recognise the device when it's in "USB Debugging" mode. In the device manager it just appears in "Other Devices" as "KHSTVQCDONA". I've tried updating the software, selecting the "usb_drivers" folder containing drivers provided in the downloading Zip file, and also tried downloading the "Google USB Drivers" directly from Google, but Windows doesn't find the drivers for this device.
If I disable "USB Debugging" the device does connect successfully under "Portable Devices", but clearly that's not much use.
I can't seem to figure it out.
Below are the steps I took in trying to get it to work. I was going to write it as a guide for dummies, but I never got it working...
Download the software from the link above. On the "Share-Online" page click the small-ish button that says "continue for free", and not the bit "DOWNLOAD FILE (regular download)" button in the banner ad (that I feel very silly for clicking several times).
Once the file "RK3188_ROOT for CX-919 FW0715 MOD by Everal.zip" has finished downloading, extract it to a temp location on your PC.
Make sure the Micro-USB port of the device is connected to a power source (either your PC or the provided AC adapter). The port doesn't seem to transfer data.
On the Agora device, go to "Settings", open the "USB" menu, and enable "Connect to PC". Without this the device wasn't recognised by my PC at all.
In "Settings", click on the "Developer options" menu, and tick "USB debugging".
Connect the provided blue Male-Male USB cable to a full-sized USB port on the device, and to a USB port on your PC. At this stage the device connects but is not recognised.
Open the Windows "Device Manager".
In the "Device Manager", expand "Other Devices", then right-click on "KHSTVQCDONA" and click on "Update Driver Software".
Click "Browse my computer for driver software".
Navigate to the "usb_drivers" folder of the software you extracted earlier, select it, and click "OK".
Click "OK". THIS DIDN'T WORK, stating that "Windows was unable to install your KHSTVQCDONA" and "Windows could not find driver software for your device".
[*] Open "Command Prompt", by right-clicking on it and clicking "Run as Administrator".
[*]C:
[*]cd RK3188_ROOT
[*]TPSparkyRoot.bat
At this point I see the following:
*---* VonDroid.com N101 II Root Tool based on work by sunnydavid *---*
--- Plug in your device, make sure debugging is enabled in Developer Options
--- This script will now copy files over to your N101 II
error: device not found

--- Reboot 1/3 - Press Space Bar once the device has rebooted

--- Reboot 2/3 - Press Space Bar once the device has rebooted
Press any key to continue . . .
error: device not found
--- If the ID shows as 0/root then continue, otherwise CTRL+C to cancel and star
t over
Press any key to continue . . .
Click to expand...
Click to collapse
I terminate at this point
I've also done the following
Un-ticked "Verify apps over USB"
In "Security", ticked "Unkown sources", and un-ticked "Verify apps"
At this point I'm totally at a loss.
I had already started using the device initially, so I did a factory reset, but this hasn't helped at all.
Can you see anything I'm missing, or point me in the right direction?
Many thanks in advance! :good:

Ok So I know i messed around with many drivers installing and uninstalling before it worked. I Thought it was the last set that came with the Root method but I may be wrong.
Also I cant remember exactly now but I am pretty sure if you activate the connect to computer you bypass the ROM and connect to the SD card and the U SD. So that would not help when accessing the root files.
Try re-installing the drivers after connecting without the box checked in settings or try the ones from super oneclick 2.3.3 or even the pocket pC ones. you may also need to uninstall the device then reconnect to get a clean run at it. Windows likes hanging onto what it thinks is the best driver even when they don't work or are completely wrong.
Also I ran the batch file form within windows not in console, Just right clock to run as administrator.
I have just used it for a couple of weeks in Japan get let the Kids watch Aview (iView) and it worked a treat. Also the latest sixaxis updates made the controller even better than before. I can probably have a tool around with it later this week but I am busy before then so wont be able to help any. It can be done!
PM me if you cant find the drivers mentioned above I can email them to you.

Thanks for the quick response.
Can you just confirm that you were connecting using the blue Male-Male USB cable, and not a USB-Micro-USB cable?
When I connect to the Micro-USB port it doesn't see a device at all. It just seems to provide power.
When I connect with the blue Male-Male USB cable, unless I have "Connect to PC" ticked, it also doesn't see a device.
I don't have a micro-SD card installed, but that doesn't matter right?
I'll try those drivers you suggest. Thanks.

I am quite keen to figure out what is different but I cant access it for a couple of days sorry.
I definitely used a full sized USB to Connect, I may have used another one, and powered it from the Micro USB direct to power supply. If you are connecting it to the PC for power it may cause problems.
I know that you cannot access the recovery menu unless you are powering through the Micro USB only. Another thing I meant to mention in my original post. I may have posted it elsewhere.

SUCCESS! After I got the SuperOneClick software to forcibly install the drivers the device was then recognised and I could root the device.
Thanks. I'll write up the full instructions.

Excellent!! Thanks for writing up the guide.

OK, here is a full step-by-step guide for getting this to work:
Download "SuperOneClick" from Download.com (CNET). I can't post external links right now because I'm a new user, but it will appear if you do a Google search.
Extract SuperOneClick to a temporary location ("C:\temp" for the purpose of this installation).
Download the software from the link in the first post above. On the "Share-Online" page click the small-ish button that says "continue for free", and not the big "DOWNLOAD FILE (regular download)" button in the banner ad (that I feel very silly for clicking several times).
Once the file "RK3188_ROOT for CX-919 FW0715 MOD by Everal.zip" has finished downloading, extract it to a temp location on your PC (for the purpose of these instructions "C:\temp").
Make sure the Micro-USB port of the device is connected to a power source (ideally the provided AC adapter). The port doesn't seem to transfer data so don't connect it to your PC, unless you are using your PC as the power source. Basically as long as it's turned on, then continue.
On the Agora device, go to "Settings", open the "USB" menu, and enable "Connect to PC". Without this the device wasn't recognised by my PC at all.
In "Settings", click on the "Developer options" menu, and tick "USB debugging".
Connect the provided blue Male-Male USB cable to a full-sized USB port on the device, and to a USB port on your PC. At this stage the device connects but is not recognised.
Open "SuperOneClick"
In SuperOneClick click the "Advanced" tab, then click "Check Drivers".
When prompted to ask if you would like it to forcefully install drivers, click "Yes".
Click the "Install..." option when prompted by "Windows Security".
You should then hear the device connect, and disconnect, and see an message "Driver installed! Please reconnect your device", so click "OK".
Disconnect the blue USB cable from you PC, and then reconnect it. You should hear that the device has connected successfully (and it now appears as "Android Composite ADB Interface" in you "Device Manager" if you care to check.).
Open "Command Prompt", by right-clicking on it and clicking "Run as Administrator". (I found that running the .bat file directly failed because it didn't find the "adb" application)
C:
cd temp\RK3188_ROOT
TPSparkyRoot.bat
Follow the prompts from here. The application should reboot your device several times (if not something is wrong), after which point you press any ket to continue. From here everything was very straight-forward once the .bat file completed the device was then rooted.
Enjoy

I had to do things differently......
Used rocketchip_batch_tool_1.7 for drivers, superoneclick didnt do anything.
I ran the batch from the folder on my desktop.
For EACH device re-boot i had to RE CHECK connect usb on cx919 settings.
I got a few errors about no more storage on my device when it tried to copy some stuff, although i have the super user and i tried sixaxis controller which requires root and it worked. Not sure what the files were.
update:
Hmm and it seems SSL websites dont work now as well as Netflix or the Store.
ill have to try something else!
Update:
did a factory wipe. all seems ok now.

Worked fine since then. All a sudden same prob, no Netflix no store. Wtf?

Just wanted to post an updated root method since i got one of these second hand last week
1. get the universal rockchip drivers, or the latest generic google ones. both worked for me on two different PC's. (including windows 8.1 x64)
2. Enable USB Debug mode in developer options. you know the drill.
3. the kogan device has a "USB" menu in settings, that has a 'connect to PC' setting. turn that on or ADB cuts out shortly after the system boots - turn it off after rooting for it to work normally.
4. connect PC to kogan dongle via the USB port next to the power LED. The other one doesnt work.
5. root with whatever method you want - i used kingo root which rooted it flawlessly first time.
6. have fuuuuun!
3 and 4 stumped me for days til i figured out what was going on. not something i'd ever encountered before, and likely unique to this device and why some people cant figure it out.

I have a Nexus 7 , and the screen is broken. I can't type anything and can't go inside the main settings, now. It's not possible to use my "look-screen-pattern"
Now I would like to do a backup of all data on my pc. (i want to open the backup file via winrar(or anything else), to get my photos, videos, apps etc. )
I have the android sdk tools installed, the google drivers too.
I used the recovery mode on my nexus. On the screen is a yellow sentence, what means the sideload function. But i don't need the sideload function. I only want a backup and no new rom system...
I tried to use adb shell commands to store a backup on my windows 7 pc.
But in my cmd a always get the same error.

Get an OTG adapter cable and plug in a USB mouse/keyboard. That should get you through the unlock.

Broken /Black display - How to transfer Data to my PC (MTP Mode)

Hello everyone,
i looked up similar but havent found a solution to my problem, so i hope you can help me on this one.
My OP 5 fell down, resulting in a broken screen. It is still fully functionally but completely black and i can access the phone via fingerprint as long as its still on. I need to get in MTP Mode to be able to transfer all the Media (e.g. the last year of my kids growing up in pictures)
Dev Mode is activated, so after i plug in my USB Cable to connect it to my PC i think i emember that i can access the selection (Charging/ MTP etc.) over the dropdown menue.
I just have to find the right spot to click.
Can anyone of you maybe screenshot the scenario?
1. After the USB is connected and the debugging window appears
2. The screen when you can select the connection mode?
I tried to use the Program "apowermirror" as well but i cant see where i have to click on the Screen when it says " allow usb debugging" when it tries to connect via USB. So a screenshot of this could work as well.
Additional Info: the bootloader is unlocked and i have TWRP, so maybe there is also a way ?! im a total noob regarding this...
Thank you very much in advance for any help on this.

Maybe in twrp you can with adb command, install adb on your computer and search (google) about the command "adb pull" or maybe just reboot twrp (power off and power with vol down) you can access storage. Have you some security? Pin or pattern?

hi, try the program through MyPhoneExplorer, you can via Wi fi
