My lg e970 running PA 3.99+ cant be seen by the computer anymore. It does not show up in device manager. It only charges when connected. I tried reinstalling the lg drivers. I also tried toggling fast charge in trickster mode on and off again, but still no luck. There is still no notification on the phone to select usb connection mode, mtp or ptp. I also tried toggling fast charge in trickster mode on and off again. I went into usb tethering and it says "usb not connected". The only way the computer sees the phone in device manager is if it is in fastboot with the nexus 4 universal adb driver. Even then, I can't see it in windows explorer as a mtp interface.

I'm having an issue where my thunderbolt does not recognize my device any longer. I used to have it set up with pdanet and everything worked well for about a week. All of a sudden, any computer i tried to plug the device into, wouldn't detect the phone. A friend of mine has tried his thunderbolt on my computer and it detects it.
When plugging my phone in, it pops up an error message with "USB Device not Recognized." In the device manager, the phone shows up as Unknown Device. I have tried this on 3 different pc's, using 3 different data cables. No USB symbol displays on the taskbar of the phone when I plug it in, however, it does charge.
What I have tried:
Changing data cables.
Using another PC.
Uninstalling device drivers and letting windows re-detect and install.
Downloaded HTC Sync and ran it after uninstalling drivers again and re-plugging the phone.
Changed different Connection settings on the phone, such as USB Debuggin on/off, and changing it to HTC Sync Mode, Charge Only, Disk Drive, etc
Mounted and unmounted SD Card in the phone settings.
OS: Windows 7 x64
Thank you for any help you may provide.
same problem
I have the same problem with HTC mytouch 3g 32B Android 2.2.1 when I plug it through usb under Vista.
Any suggestions?
Try installing the usb drivers from htc if you haven't.
http://dl4.htc.com/RomCode/Source_and_Binaries/USB_driver_20101122_release.zip
I have download the HTC usb drivers but when i go to control panel and uninstall the unknown device it just reinstalls it. when i try to update drivers using the location
ie C:\Users\sxristi\Downloads\android-usb-driver\Android USB Driver\i386
i get a reply
The best software for you device is already installed. Windows has determined that the driver software for your device is up to date.
and it continues to point to
unknown device
Oh one more things i got the usb drivers from Android SDK Manager the google usb drivers revision 4 and the weird thing is that i do not get the trident usb nor the debug icon on my HTC when i plug it in to my vista. I did get it once or twice before but not in general since the usb devices are not recognized. However when i boot on my Ubuntu os then i do get them recognized. so i guess the problem is with windows drivers somehow...
Thanks for the replies.
I've tried to install the drivers from HTC but Windows says that the driver is not compatible with my the device.
Also, I tried on a system with Windows XP and everything worked as intended, but I cannot get it to work properly in Win 7 x64 anymore.
When my win7 comp no longer sees my Tbolt I have to toggle the USB Debugging off then back on. Usually within a few seconds it reads it again. If that does not work I have also used the option to turn on internet pass through then change it back to hard drive mode. Either of those usually work for me. My drivers I used were from android sdk if that makes any difference. Hope this helps.

HTC
My problem continues under Vista OS. I called HTC and they told me to re install their Sync after removing Adobe Air and all HTC drivers and Google USB drivers. I did that and reinstalled Sync and still nothing. They also told me to call microsoft for it seems operating system conflict.
My conclusion yields toward windows conflict. But I can not figure out this conflict. Perhaps something I have installed does not let my vista recognize the HTC android device and uses the windows usb drivers to create this "Unknown Device" under usb serial bus controllers. once it is an unknown device forget about Sync or ADB etc... The phone is just not recognized as android and you can not do much with it via windows.
For the person who suggested to turn "USB Debugging" on-off, i did that and still the computer recognizes that there is a usb device but again it says "usb device not recognized unknown device.."
any additional suggestions???
I've verified that my phone works fine on Windows XP. I still cannot connect to windows 7, though.
Try turning OFF Fast Boot and turning ON USB debugging. this helped for me.
same problem
I have a similar problem too .. i know its not the computer as other phones and pen drives are working ok.
Plus this phone has same problem on other computers too, where as other phones work fine.
So it has to do something with the phone and not the drivers or computer in anyway
I have the same problem, no PC recognizes my HTC Thunderbolt. Now change cable and tried with windows xp, 7 and 8. Is there any solution I can not root. I want to change the rom factory rom I do not like but I can not do anything because I do not recognize the usb. Also the menu does not appear when I connect via USB in the notification bar.

I'm having the same issue, with an HTC Rezound... just flashed a new rom, need to update boot.img but can't see my device via adb or fastboot... have tried changing usb cables, phone is in FASTBOOT mode... reinstalled HTC Drivers, just get USB Not Recognized error (Windows 8 64-bit)...
Any solution for this?
Yeah, so i've read plenty of topics about USB problems, but none gave me the
anserw.
I'm running Villain ROM 3.0. I just cant connect my phone to the computer (Mac).
It work well before also after flashing Villain.
What i tried:
1. connecting my phone without usb debuging ->phone gives the sound and report in the notification bar : "MTP - initializing" then "USB Connected, MTP-connected" But it does not gives a connection with my mac.
2. Connecting my phone with usb debuging ->phone gives the sound, but nothing happens. nothing in the notification bar neither on the computer. It's strange becouse before it was making the same sound and giving me the info in the notification to connect.
3. I've also tried KIES air it works fine. i can see my phone content, but when im trying to send one file (130mb) there is no reaction to this.
Also some time ago i was able to get usb working by simply choosing usb debuging and restarting phone.
But now i have no acces to my storage
Please help
I have a similar problem.
When I connect my SGSII to my PC (with USB Debugging On) I see 2 Removable Drives in Windows' Explorer. If I click on either one I get the "Please Insert Disk". If I connect to the same USB with USB Debugging off, then Kies Starts but does not connect.
Now the weird bit, if I do the same thing in the next USB port, then everything works fine.
Going back to the first USB slot then the problem reappears.
The 2 USB slots are next to each other and go back to the same controller on the motherboard. I have removed Kies and reinstalled Kies. I have uninstalled all the drivers. I have even changed the USB cable. When I plug a USB External Hard Drive into either USB, it works fine.
Maybe the phone just likes the one connection per computer. I'll have to test that out in my work's PC.
Update:
managed to get a microUSB cable and tested it on my work's PC. Exact same situation. Both PCs run Windows XPpro.
Has anyone else noticed this?
Now, when you said that, i checked with my second usb por, and everything works fine .
So thanks for your help. One working with sgs2 usb port is enought for me
I recently started to root my LG phone but it failed throughout the process. Now everytime I connect my phone via USB to my computer charges my phone but my computer won't show it or read my phone like it is not connected nor will my phone say it is connected to my computer. I have the drivers downloaded. Is there a way to fix it?

In 1990 to 2002 we have been using Serial Ports (COM1, COM2) and Parallel Ports(LPT1) for devices and they never gave connect problems like USB gives. USB works for some time and then the driver gets damaged or devices not recognized due to Voltage Problems, etc etc.
USB problems are very common these days. First thing you should try is, UNINSTALL DRIVER from PC and Restart PC. Connect PC to Internet, then reinstall latest LG Android Driver and connect phone with USB. Phone will install drivers for Slow Charging mode,...
...then select usb mode to PTP, phone will install driver for PTP,
...then select usb mode to MTP, phone will install driver for MTP,
...then select usb mode to LG Software Mode, phone will install driver for LG Sorftware Mode.
Now your phone is set for every mode you need. Hope this helps

My phone isn't being detected by adb. Almost as if USB Debugging isn't even enabled (which it is). ADB is just blank when I run adb devices.
I've installed the LG VZW G3 drivers. Any suggestions?
Make sure you change the USB mode to internet and then Ethernet. Took me a while to figure that out.
Make sure you have developer options visible
Enable USB debugging
Connect your phone to your computer
Pull down and change the USB connection from installer/MTP to internet > ethernet
Open Command Prompt window where ADB is installed, and type in "adb devices"
Allow when you see the RSA prompt
Run the batch file for ioroot, type "adb reboot recovery", install from adb, run sideload command, and then reboot
Also, make sure you're running the latest version of the SDK. Mine wouldn't work until I updated. HTH!

Use the LG USB drivers for Verizon Wireless!
Change the usb connection mode to Internet/Ethernet
My adb was the problem on mine. I had to reinstall java jdk and the sdk and worked perfectly the first time I tried after that

Either I'm completly blind or ... my G3 doesn't have that option. I only got "Charge Phone", "Media Device (MTP)", and "Send images (PTP)" to configure the USB PC CONNECTION. I also have the option to switch on USB tethering, but that doesn't change anything for the better, either.
Where's that Internet/Ethernet connection mode hidden?
The internet option might not appear until the usb is connected to the pc. Recheck available options while connected.
-Set phone for PTP connection
-Plug phone into PC via USB. You should see a driver loading/loaded message on your PC
-On the phone, change USB connection to Internet, then select Ethernet on the submenu that will appear
(PTP seems to "wake up" the ADB driver on the PC side for me. This was mandatory on a couple of prior phones/tablets, so it's what I did with the G3.)
Or switch to Linux and never hear about drivers ever again!
Verizon on Windows 8.1
So, the problem I had on windows 8.1 was that when you connect the device and it asks you what action to take automatically, you need to click that and install the Verizon stuff. I had my phone in USB debugging and Ethernet mode while doing this install. After it installed everything, the window on my phone for debugging permission showed up, and I allowed it. The phone now shows up in adb. I don't know if this was obvious but I thought Id mention it anyway
After the last G3 update from Verizon, the Ethernet option is gone. I can't get it to talk with ADB any longer. I see the developer mode come up on the phone, but it never asks for security key or appears in the ADB list. Anybody have any good ideas? This is on a Mac and I've never had a problem before doing this.
EDIT: After juggling back and forth from PTP to MTP to PTP, restarting ADB, I got it to connect. No clue what the key was, but working again for the moment. The Ethernet option is still gone from the phone though so that simple fix is no longer an issue.

I installed the skydragon rom, which is based on stock so probably the same. I found that PTP worked but MTP did not. This is in Ubuntu Linux.
I tired EVERYTHING, and simply get get any of my computers to see the zenfone max.
When I plug the phone into any computer, nothing will show up on the computer side, and on the phone side it says charging.
-Yes I enable developer mode
-Yes I tried USB debugging on and off
-Yes I tried the usb options for Charging, MTP, PTP, MIDI
-Yes I enabled unknown sources
-Yes I tried 5 different cables
-Yes I factory reset the device twice and same thing
I tried all the options above, all in different sequence, and still nothing.
On both windows and linux machines it doesn't show up when I try "adb devices", and on linux when I try "lsusb".
Really stuck on a crossroads here if anyone can shed any light..
edit: When your trying to fastboot, do you need to put the phone in recovery mode and select "apply update from adb"?
