Hi all,
I have a problem that the PC can not recognize my Stratos (chinese version), when I pluged in, it showed the error "USB device is unrecognized". I tried all the possible solutions such as re-install driver, change USB driver to USB Composite device, install ADB driver and try with different PCs, but it still doesn't work.
Anyone have a solution for this problem? Thank you in advance.
Only other options are trying to use another USB port or find another charger that has data connection (third party chargers usually don't have data connection).

I have tried all of these. Do you know any software (driver) issues that can lead to that problem??
The only time I've seen something like "unrecognized device" or "unknown device" was when I was trying to boot my watch to fastboot manually, and if I waited in the screen where you select either fastboot or "full erase" then then computer would recognize it as an unknown device (it was actually in a mode that wasn't either fastboot or adb/composite).
But Windows is very weird, sometimes it won't install the correct driver even if you have installed it previously. You may want to do something like is shown in this thread to make sure the computer picked the correct driver (don't install anything, just make sure the correct driver is being used, either adb or composite should work):

yesterday I tried to clean the pins before plugging in and it worked, on and off. So I think its again a stupid contact problem. Thank you.
Simply clean the contacts
Hey guys, it´s simple, take a sharp knife and simply clean contacts on your watches. It just worked for me
It's better just to clean with soft soap, max alcohol. Scratching contacts is bad idea. You are removing non-corrosive layer. But Stratos doesn't have gold plated contacts, maybe the whole pins are non-corrosive...

Hi all
I have a problem with my hero not being recognized by my PC. This happened after a weekend trip and i charged the phone with iphone USB adapter as i lost my one and now after returning from my trip i connect my hero to my PC to be greeted with the "USB Device Not Recognized" message.
Also my Amon_Ra recovery i used has been wiped and i cant get into recovery or install any rom at all.
I am thinking this might be the same USB brick that affected some Desire owners but i am not sure.
So please if anyone can help me, please do.
Thanks in advance.

this happen to me. What i did was switch my phone off, plug in the usb and switched it back on. then wait for windows to say it not recognised. then go to to device and printers and uninstall the drivers for the phone. Disconnect and reconnect the usb back to the phone and it it will pick it up.
Can you try booting in fastboot and tell me if that is recognized?
it still doesnt recognize it in fastboot

Sounds like its just a driver issue. Have you tried plugging it in, when you get that message open DEVICE MANAGER,... Find the yellow "!", right click it, uninstall, unplug phone, reboot PC.
.... Then use BTDAG's [Guide] How to Setup Correct Hero Drivers (for x86 & x64 users)
I hav the same problem. In recover mode it works but then turn on the phone, there is no popup options as before. Tried around with drivers but didnt work either. But found a solution which is very convenient. I dont know if it works on other ROM versions but I'm on 2.1 (Villain10).
- Install extended control widget (dont remember where I got it but you can google, it seems I cannot find it on the market)
- Add this widget to the home screen: Menu/Add to Home/Widget/ Extended Control bar (you can choose the size from 1x1 to 1x4) then select "Mass storage" at the bottom, apply.
Now you have a widget to turn on/off USB storage. When you connect Hero to the PC, just click on this widget then the PC will connect to the SD card, and click one more to turn it off.
ok i will give that a try

No i havent and i gave up trying because i dnt think there is a fix for it. if yours is unrooted and the warranty is still valid you should consider returning it to HTC maybe they might replace it

Did you try that?..... You need to do the reboot PC/Laptop after uninstalling ALL HTC drivers! Then when you reboot PC, plug phone back in, should say "not recognised" again,... then follow BTDAG's guide. T'is definitely a driver issue!
tried flashing 3 roms, modaco, radug and now kimera... none working.
can connect in fastboot, it shows up in device manager as android 1.0
ive tried 3 different usb cables and 4 differet pcs, still there is no response on my phone !!!
using villian rom 10.0 rite now.
okay it boots up into fastboot and fastboot usb shows up on the screen in red,
BUT when i use the "adb devices" command in adb it doesnt show the device,
it is showing as android 1.0 in devices and printers (windows 7)
You need to use....
fastboot devices
....when your are in fastboot.
What happens when you go into your recovery, select "Toggle MS/USB" with USB connected to PC?
okay
fastboot devices command shows some serial number.
then i tried adb remount, it gave an error....
enabling usb-ms with cable attached gives no response
ok i think it might be USB driver like ddotpatel said but i am not sure.
i reinstalled my whole windows 7 to 32bit now instead of the 64bit version i was using before and today i just connected my hero to my PC and windows 7 did its thing and installed the drivers and finally my hero can mount the SD card in my PC again although i kept getting this can perform faster in USB 2.0 port or something like that i didn’t care as long as i can mount my SD card again.
now went into fastboot and used the fastboot device command and i could see my hero serial no. but when i try to flash the amonra recovery i got the permission error (i cant really remember). i tried flashing using the adb method but still no luck.
so i went to market and downloaded rom manager and used it to flash clockwork recovery and now i could boot to clockwork recovery.
from this recovery i can now flash any rom i want and although there are still a few more problems i am glad now that i can flash custom roms again.
the problem i can see so far but i can deal with is
1. i don’t think fastboot commands work even if the phone is detected.
2. SD card mounts at USB 1.1 speed. (i have tried different ports and cable but still the same thing and this is the ports i use for my N1, Desire and my other android phones with USB 2.0 speed)
PS: adb commands for pushing and removing apps is working.
Hope this can be helpful to those experiencing the same problem.
Instead of re-installing your entire OS just use usbdeview to remove the failing drivers.
Also remove any old HTC Sync installs and install the latest version.
For some reason, whenever I plug my X10a into my computer, I get "USB Device Not Recognized", and the phone doesn't charge and I can't mount SD Card or use ADB...
It still charges through the wall socket though.
Anyone know what the problem is?

Your computer or SD. Uninstall any SE drivers with USBDeview and reconnect which should install new drivers and hopefully sort it out.
Thanks for the suggestion, but it didn't work...I tried connecting to another computer too, and nothing happened. So my only option now is to get a new SD card?
Hi, I am experiencing the same thing and this happened after that I first rooted my phone using superoneclick and then replaced my fonts with arabic fonts.
I hope someone can find the root cause for this error.

I've had off and on problems in this area. Searched around and found this thread.
[GUIDE] ADB, Fastboot, and Nandroid for Noobs
This is what he suggests to solve problems with ADB and USB, (below is ALL the work of the Guide author):
"Im not getting a notification of Android ADB when i plug in my USB"
Why: Your computer has detected your phone but as a protable device and as a storage device.
Fix: This took me a lot of research and time to figure out so this is what your are going to do.
First download USBDeview - Here
Unzip it
Run USBDeview.exe as Administrator
You will see all drivers being used on your computer
Highlight and Uninstall all drivers with the description have HTC Android (Should be 3 of them)
Right Click on the driver and press uninstall
Once done, Unplug your phone and plug it back in
You should now get the notification of the ADB device
Plug in your phone through USB and DO NOT MOUNT IT!!!!!
Your computer should see a new device and try to install Android 1.0 driver (If it doesnt, scroll down to the "Im not getting a notification of Android ADB when i plug in my USB" section)
Let it load
Once it cant find them select "Install drivers from my pc"
The drivers you need are in the Android SDK 1.5r2 folder (C:\android-sdk-windows\usb_driver)
Depending on your OS pick x86 or amd64
You ADB Android Device should now be installed! Good Job

Had the same issue my friend. it's the USB socket within the phone that is gubbed. I spent days searching for a solution to no avail.
Why don't you install PC Companion? You can download it from SE. Once you've finished installation, connect your phone and let it detect your phone.
After that, you can uninstall PC Companion. The purpose is to let PC Companion installs all X10 drivers.
Hi guys,
Well it's not the socket because I can charge it normally with wall charger. Regarding the drivers, of course I have tried with PCcompanion and it didn't work.
Thanks...
well i think it can be the socket, becouse, wall charger only uses two wires of the five the socket has, so may be data+ or data- wire is broken. Have you tried with different usb cable?
As the mobile usb socket only has TWO solder points and it is very small socket and the position is not the best, may be some of the five lanes of the socket have unsoldered...and this is why it charges but it cant connect to computer.
It is only an idea..i hope the cause is some driver, mobile configuration (have you tried to reset your phone? ) or the USB cable.
after changing 3 cables I got it to work...
Thank you for your support.

nvm i downloaded the file from nirosoft.com instead and it works fine.
USB Controllers
Usually if it works on another computer, but not your own, it is because your USB Controllers are messed up. In Device Manager go to Universal Serial Bus Controllers -> right click each one and say Uninstall(your USB mouse/other peripherals will stop working so be warned) -> restart your computer and let it install all the drivers again. Should be working now.
I'm on v2.3 and taking out the battery and SD card and re-inserting it solved the problem for me.

I'm still having this issue. 3 cables 3 computers I think its my port. Charges fine when I plug it into wall or computer.
Just nothing for data its like nothing is happening.

Hi, I have a Galaxy Player 4.0 that I rooted with SuperOneClick. It was working fine at first then a couple of weeks ago, I noticed that my PC no longer recognizes it as a device, it just charges when I plug it in. So, I looked around andn tried a few things:
Restarted it several times
Tried with all the different modes in USB settings
Tried with different cable
Tried with two other computers, a Mac Mini and a Win7 laptop
Tried to unroot, couldn't get that to work
Did a factory data reset
Nothing works. I can't remember anything I did since rooting that would cause this, except I installed the Samsung Kies driver on the PC. I can't remember if the USB mass storage was working after Kies. Does anyone have other ideas?
Bump. This is rather a big deal, as I cannot transfer files between my PC and Galaxy player in any way other than over WiFi, which does not work reliably. I don't have a microSD card adapter either.
You might want to check if anything related to samsung/android appears in the device manager. Alternatively, to use heimdall I use Zadig to switch from samsung's driver to libusb but it does show you everything connected to your computer via usb when you check the option to list all devices. You should try this with and without usb debuging enabled. If nothing shows up you know it id your player that is at fault.

Thanks,
The first time I plugged it in without USB debugging enabled nothing showed up, when I enabled USB debugging, in Zadig and Device manager there showed up an unknown device, trying to update driver in Device manager showed that it already had the best driver, and in zadig driver replacement failed. Now, when I plug it in, either with or without USB debugging enabled, nothing shows up anywhere. I have tried with other computers and other cables, and nothing works, so I am pretty sure it's the player. I am willing to to a complete factory system reset, but I don't know how.

I'm having the same problem with my rooted 5.0. Although it's not a huge problem for me (I use dropbox for file syncing) I would love to sort this out, let me know if your factory reset works!
You can find it in the Privacy section of the settings menu.

I suspect you have a faulty usb connector on your device, but it doesn't hurt to do a factory reset. But you might want to backup your data first Did you try to jerk the usb cable in your player? A loose/broken connector would explain all your problems. Even if it is a software problem, I can't see how to flash your device with the original firmware since you don't have a sdcard & usb doesn't work...
Btw, I was referring to zadig only to show the devices attached to your computer, not to change the driver!

Thanks, I only tried to change the driver because it showed no driver already installed. I have a bit of electronics background so I may crack it open and take a look at the connector. I already tried the factory reset in the privacy menu, but that only wipes data apparently, not the system. I do have an sd card, I just don't have an adapter to the PC.
EDIT: After wiggling the cable around a bit, it showed the USB icon in the status bar, so I clicked connect USB mass storage, but the computer still showed a badly installed driver and then after some more wiggling the icon disappeared, so I am pretty sure it's a problem with the connector. BTW, how would I flash the stock firmware to unroot?
I plug my phone into a USB port.
The first time I did so, an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
The LG United Drivers are installed onto my computer great.
But then an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
My computer attempts to install MTP USB Driver, but fails. According to Windows, the device is unplugged.
The AutoPlay window reappears. Repeat from the beginning of the paragraph.
What have I done to deserve such trouble, LG?!?!
Apparently the drivers installed directly from phone are not enough. In any case, I was observing similar behaviour *until* I installed LG PC Suite (which you should have been prompted to do too). It's stupid, it sucks but again, it's LG.
Install the LG drivers first. After that, when you plug your phone, it will be recognised as an mtp device.
Have you got Windows Media Player installed?

Tried uninstalling the LG U2 USB Driver, then disconnected and reconnected phone. Same problem. LG U2 USB Driver was installed but MTP USB still shows up as unplugged.

I have already tried what you said as I posted before. The LG United Mobile driver gets installed but the MTP USB Driver does not get installed due to the device being unplugged according to Windows, even though I have yet to disconnect the phone from the computer. The phone still says "Connected as an installer".
The phone is recognized as an F: Drive by Windows but LGE Mobile but keeps disconnecting and reconnecting every 20 seconds or so.
I am going to have to upload a video to YouTube to make things crystal clear.

Try a different USB port or cable. My P769 would not work on my USB 3 ports, but was happy on the USB 2 port. I had already installed the drivers and LG PC Suite and it picked up each mode just fine.
Plugging the phone into USB 2.0 makes the phone show up in portable devices, but LG Suite fails to identify the phone. I tried using both LGE Android Net MTP USB Device and MTP USB Device but they both fail. I have LG United Drivers and LG Suite installed already.
got thesame problem here mate..i search all over here and google the driver but still cant find any solution..this is so frustrating to fix this issue,,got install and uninstall the pc suite and driver many times but still cant get the solution..so what could be the fix????
no one can suggest..someone told me that maybe its causing the broken data cable but i have 3 cables now..
everytime i intend to install the MTP driver thing my pc always failed to do so,,saying that the filename,directory name or syntax label is incorrect..but i manually direct the search to lg driver folder but same error occurs..or there still other alternative apps that can transfer files without removing my sd to my phone,or atleast transfer files over the wifi..??
Any fix for this one? Already tried uninstalling, installing LG drivers, removed and reinserted SD card and everything. But still to no avail. It installs everything successfully EXCEPT USB MTP device which is the one I needed the most. Any solutions? Thanks!

You must be on 64 bit windows. Not even on 64bit, Still try this...
1) Uninstall LG Drivers, LG PC Suite and anything you see named LG. Restart PC.
2) Install latest LG Driver from this post (step 4)
3) Install Optional MTP Driver from this post (step 4)
4) Open Windows Device Manager (just to watch whats happening.)
5) Disconnect Internet (To avoid stupid online WDM drivers)
6) Connect phone with Usb and let drivers install automatically. Give it some time to install drivers keeping watch on Device Manager window.
7) Keep changing USB connect modes to all modes one-by-one on Phone and let drivers install.
You should see MTP drivers installed now. If this does not help, cant think of anything else. If this works, press THANKS button
EDIT: Connect USB at backside of pc, directly to USB on pc motherboard.

I plug my phone into a USB port.
The first time I did so, an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
The LG United Drivers are installed onto my computer great.
But then an AutoPlay window pops up prompting me to run LGAutoRun.exe. I click to do so.
My computer attempts to install MTP USB Driver, but fails. According to Windows, the device is unplugged.
The AutoPlay window reappears. Repeat from the beginning of the paragraph.
What have I done to deserve such trouble, LG?!?!

This works on XP x86
Need:
1. LG USB cable that came with the phone,
2. Media Player 10/11 preinstalled,
3. your LG Driver,
3. LG Phone,
4. and Media Transfer Protocol Porting Kit (mtppk12.exe)
1. with phone disconnected install Media Transfer Protocol Porting Kit
2. when asked to restart the PC, go ahead and restart
3. open device manager, connect phone to PC
4. install driver and watch LGE Android MTP disappear
5. be sure to toggle between Charge and MTP on the phone to install all drivers
this also works for HTC MTP
Hi,
After the most recent update (OTA), when I connect my phone to my PC, regardless of what mode I have the USB set for on the phone, I can no longer connect
to my phone.
It worked flawlessly before.
The Huawei HiSuite also cannot connect (although I don't norm ally use that anyway).
I have tried reinstalling ADB and also HiSuite to no avail.
One thing I do notice is that there was a HDB driver missing. When I rebooted my PC it has now changed to 'USB Composite device' but shows the error
Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)
{Bad Image}
%hs is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status 0x
I've tried to automatically install a driver, again no joy. (Because the device is not recognised, it just says it could not a find a suitable driver).
If I uninstall the device and then plug my phone back in we then start with the HDB device (for which there is no driver according to MS), which upon reboot becomes the 'USB Composite device' again.
So, anyone know how I can fix this? I'd like access to my phone through my PC if possible.
TIA (Thanks in Advance)
I know it's obvious, but have you tried a different usb port.

Yes. Front and back of PC as well through a hub.
It makes a sound like it connects, then I get a popup on my phone "Charge only / Transfer files / Transfer photos" and regardless of which one I select, it then disconnects.
Somewhat annoying. It worked okay before latest update.
I've even reinstalled ADB, even though I'm fairly certain this has nothing to do with it.
Thanks for your reply anyway!
[Solved]
I managed to solve this by plugging in my Honor 9. On the device manager page in Windows take a look at the 'USB Composite Device' item and selecting with an exclamation mark against it and right click it and select"Uninstall device" from the menu. When it asks to remove the driver, select yes. Unplug your phone. Reboot your PC. Upon plugging your phone back in, your device will be re-detected and Windows will install the driver correctly.
