Phone can no longer connect to PC.

I tried connecting my phone to my laptop today and it said installing drivers. It was working yesterday but today for some reason it was trying to install drivers again. It failed, so I downloaded the LG drivers and installed them but my laptop still tries to install the drivers and fails.
I already tried uninstalling the drivers and installing them again.
This is what it says under Device Status
This device cannot start. (Code 10)
EDIT: I got it working by turning on USB Debugging mode.

by any chance did you ever figure this out? I flashed my g2x to hellfire ICS 4.0.4 and while I once was able to get the drivers to work, now I get the same error This device cannot start.
i have usb debugging and unknown sources enabled, but mass storage on my phone is disabled. is that related?

[Q] Trouble mounting file system to PC

Ive tried removing and reinstalling drivers. Seems like I have some issue whenever I try to mount to my pc it refuses and starts slashing the usb connected at the very top bar and then back to disconnected. Ive tried different ports, different cables to no avail. Also...if I try to plug into the ports directly on my laptop..it will simply fail and say no drivers installed. Whe it is seen by the pc its telling me the Quallcomm driver are not there. It was such an issue that when I went to flash back to stock the computer wouldnt recognize it and I had to set up a second pc to flash back.

Seems windows has decided that it is a Qualcomm HSUSB device and wont mount on the second laptop now.

Does your phone power on? When people are hard brickdb thats the same thing thay happens

nah its up and running fine.

In that case very strange. Did u try deleting your drivers. Restarting your pc then installing kies?: it has the drivers you need

I had this problem before, what I had to do was remove any evidence of any Samsung Drivers on my PC, uninstall Kies. Then reinstall Kies, and keep it open while you connect your phone. That worked me, hope it works for you?

did you go as far as deleting everything from the registry? Ill do it Monday when I get to work as I didn't try the re installing on kies. Just odd.

No love and now same issue on two laptops. I have removed drivers and kies and tried reinstalling kies..removing installing drivers. What I AM seeing is
Even ID 5038 in the security logs
Code integrity determined that the image hash of a file is not valid. The file could be corrupt due to unauthorized modification or the invalid hash could indicate a potential disk device error.
File Name: \Device\HarddiskVolume2\Windows\System32\FsUsbExDisk.Sys

Other devices plug up to both laptops just fine??
i had something like this happen. and i had to remove all samsung drivers and and went into device manager and unistalled any updates. rebooted. ran the samsung drivers again. then rebooted. and it worked.
the other time this happened, i did the same procedure with the rebooting and installed keys and rebooted and left kies open while pluging it in (with a pc internet connection) and it searched and found the drivers online.
if you have tried both of those then im out of ideas.
hope it gets resloved.

I actually rebuilt an entire system to test it out..I have it working on it but its still not recognizing %100. Ill keep banging on it between user calls

[Q] device not recognized over USB

I've been trying to connect my Trasformer to my computer over USB for a while now so that I can use Nachoroot. When I plug it in, a bubble pops up on my PC on the bottom right saying "USB device not recognized". If i go into the device manager and click update driver and have it look in the folder with the USB drivers from Asus's website, it says that i already have the most up to date drivers. I've tried uninstalling the device, installing the package with Sync and web storage, but get the same result.
I have tried using a different cable, a different computer, and a different operating system (specifically windows 7, windows 8, and ubuntu). I've also restored my Transformer using the option in Settings.
Anybody have any ideas as to what will work?

Have you install Asus PC sync?
If you haven't you should

yes, i've installed sync.

Take a look at this thread, especially the "trouble shooting" portion
http://forum.xda-developers.com/showthread.php?p=13635629

I had looked at that thread before and have tried all of those steps, and tried them again, but no luck.
One note being that with the other drivers from the hotfile download on that thread, i'm unable to install them. In the device manager on my computer, when I plug the computer in it shows up as an unrecognized device, and when I try to use those drivers it says that they don't apply.

I am having the same problem. I was rooted on the 3.2.1 system with a US version BAO transformer TF101-A1 and the computer was able to use the drivers. However, I could not upgrade and was having issues unrooting, so I did a factory reset then upgraded OTA 3 different times until I got to the ICS 4.0.3 (which runs fine, just unrooted!). Now I cannot get the transformer drivers to install! I get the "USB Device Not Recognized" error and in the device manager it shows up as an Unknown Device under Universal Serial Bus Controllers. I try to update the drivers using Asus drivers, Vipormod drivers, and the drivers I used to originally root it which was Brks_rootkit_v7, but it won't accept them. This is without Asus Sync installed and trying on four different computers using Windows 7 64 bit and two different cables. I even tried loading the Asus Sync and it will not find the device. When I try to boot into stock recovery, I just get an Android that falls over with a red exclamation point. Also to note, my wife has a transformer still on 3.2.1 and rooted and it recognizes it immediately on all four computers using either cable. I have been everywhere searching for an answer (including this site) and tried just about everything. I just submitted a service claim email to Asus telling them that after the update I am unable to use Asus Sync and the drivers aren't recognized. I am extremely frustrated! Any help will be appreciated.

These also seem to be a similiar problem and as yet a solution has not been found.

Thank you for your quick reply. I will head over there.

Just to clarify, I can download the appropriate file, flash that file (using cwm) and then it will boot up in ICS or do I need to update to ICS after that?
Thanks,

Suddenly getting "Device driver software was not successfully installed"

I have an AT&T HTC One X and a Samsung Galaxy Tab 2 7.0 (wi-fi only). Since I got this new laptop several weeks ago and installed the Android SDK and HTC and Samsung drivers on it, I've been able to connect my devices and use adb on them with no problems. Now, however, whenever I plug in either device I get the above "device driver software was not successfully installed" message. I have tried uninstalling and reinstalling both HTC Sync and Samsung Kies. I tried deleting the driver from Device Manager before reinstalling HTC Sync, and I tried manually pointing it to the Google Extras USB driver, but nothing seems to be working. I have no idea what threw ADB out-of-whack, please help!

Nvm, apparently the Galaxy Tab 2 IS working now, after uninstalling and reinstalling Kies (as well as updating the device firmware). Which just leaves the HTC One X...at least this means that it's likely just a driver issue rather than some setting I changed on my computer.

Usb drivers for your android phone

USB Drivers are let your PC communicate with your device.
If you are executing some ADB Commands, you will need USB Drivers installed which will let the ADB server on your PC communicate with the ADB client on your device. If there are no USB Drivers installed on your PC, you will not be able to perform activities on your device via the PC.
First of All I would recommend you to install Universal ADB Driver Installer.The Universal ADB Driver installer detects your phone and installs the ADB drivers for it.This tool developed by drsmart is your solution to the “device not found” error you might get on executing ADB commands.

MORE DEVICES WILL BE UPDATED

Thanks for the info. I tried the univ adb driver installer but it showed I already had the right driver installed. Windows explorer can see my phone but other apps like HTC Sync or myphoneexplorer can't. This only happened after I rooted & installed a new rom. Maybe the rom is faulty...

No access to USB debug
I give up and need some professional help...Ya both kinds.
Here we go, I have the Galaxy 3 d2att I747
Rooted
I was running CM 10.2 with latest nightly, I think 20131208 and decided to update to CM11 via my Cyanogenmod updater but before I did I had read somewhere I should change from CWM recovery to TWRP so I downloaded Goomanager and updated to the TWRP version for my phone then went for the KitKat update and thats when the trouble began.
I am now stuck in a boot loop even if I try to boot into TWRP all I get is the TWRP boot logo then straight into boot loop again. I am almost positive I did a factory wipe as well as cache/dalvik.
Not being able to use TWRP to get into recovery I thought I would just use Odin but I can't get any of my laptops to recognize the phones USB, I just get the windows usb driver error and have tried to install the drivers manually via device manager using my samsung 7 chronos with windows 8.1 and my acer with windows 7. I updated drivers using Samsung Kies and from the website, no luck.
I also ventured into an area that I have no expertise in but I guess thats how we learn so I downloaded the Android SDK thinking I could use it to download and install the google USB drivers that way, but I can't get out of boot loop to make sure USB debugging is checked. The only thing I can access is the stock download mode which would be great if I could use the USB connection.
What am I missing? Any suggestions?

USB Not Recognized Error
I noticed that my phone suddenly stopped being recognized on both my Windows 7 and Win8 laptops. I have been trying to fix it with the drivers but to no avail. However, I plugged my phone in with a different USB cord and voila it was recognized and working. Maybe this could possibly be a simple fix.

My computer stopped recognizing my Skyrocket
Hi Everyone,
I also am having trouble with my win 7 computer recognizing my Skyrocket suddenly. I have been using several KitKat roms and they have been working just fine, except for some reported bugs that the CM devs are working on. I even was able to connect to the computer and explore both my internal and external drives. Then suddenly that stopped and the computer gave me a need to get drivers warning. I've tried to download drivers from Samsung and the computer says they are already installed. I also tried the universal driver download and got the same message. Any help would be appreciated. Like the others on this forum, I wouldn't be able to odin if I got in trouble.
Thanks for your concideration,
drewfs7270

I switched to a different rom and now it's working again !

Also, any mobile manufacturer website has guides or direct downloads for drivers. Otherwise uni drivers suffice.....

soft brick
I face bad experienced, the tablet can not boot ( after install TWRP ) but enable to enter the fastboot mode and can be detected by the computer as android adb interface but adb can't communicated with the tablet. (list of devices atached)
I do have a backup file ( I make it before soft brick, I make backup using dd command, because I don't have cwm/twrp recovery ).... but how to flash it ? Tablet chipset is wonder media 8980 OS android 4.2.2
I can not flash it by adb/fastboot.
Maybe someone here can give me a little guide for how to....
I really appreciate for your kindness

Hey, I made an expirience, which might help other users as well.
I have a Sony device (Z1C) and use Windows 10, maybe this will help for other brands and for other Windows 10 users.
I installed drivers for my device and was able to use adb. When I put the phone into fastboot mode, it was not recognized anymore. I found out, Sony has a seperate (updated, maybe?) driver for fastboot mode. When I tried to install this, the driver was not signed and Windows refused to install it. However, you can enter the UEFI (successor of BIOS) and enable installation of unsigned drivers (at own risk). Then I was able to install the fastboot driver and controll my phone in fastboot mode as well as in adb mode.
In conclusion: You might think you installed drivers, because you did, but maybe you did not.

Even on LineageOS page, many people fail to mention that, you DON'T and SHOULDN'T install any generic or universal ADB driver if you have Samsung device. As you can just install Samsung USB Drivers officially from Samsung site. Samsung USB Drivers already contain ABD interface driver just fine so Universal ADB driver is redundant for Samsung phones.
