After rooting the phone (in this case to leedroid) I have been having trouble with 2 xp machines at work.
Both detect the phone as "unknown device".
Doesnt matter what I select, charge only, sync, disk drive, adb usb debugging.
I have uninstalled / reinstalled htc drivers repeatedly.
Tried just using android sdk drivers.
I have deleted
C:\WINDOWS\system32\drivers\Wdf01000.sys,
2. Remove: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Wdf
3. Remove: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wdf01000
I have also removed anything under Vid_0000&Pid_0000
Everytime I plug it in, windows detects it as unknown device. It wont let me update the drivers.
Help please!
what do you mean it prevents you from manually updating drivers? has it ever worked before? have you tried showing hidden devices via command line then removing the old device manually and then reconnecting it?
yep did all that hidden devices stuff too.
You wont believe this but I saw a post about someone using a thicker usb cable. I recently switched to using a retractable micro usb cable at work. I brought the original htc usb cable into work today, plugged it in xp detected the phone straight away!!!!!
who would have thought a cable was the problem!!?? All that wasted time!
I restored my computer last week and since then I haven't been able to connect my sd card through the micro-usb cable. The drivers for it will not automatically download and I have already gotten the official Samsung drivers from the website. The drivers that aren't downloading are
SAMSUNG Android USB Modem
Android UMS
S3C6410 Android Adb
Any help or places that I could get these drivers would be greatly appreciated
Yeah, I was having the problem. What is your operating system?
I tried rebooting with it plugged in, although sometimes it would knock out my keyboard drivers? I even sometimes had to reset cmos... However, if you plug the cable in the back of the computer (Directly into the mobo) then it should work when rebooting. Just make sure you are in mass storage before you reboot the computer.
It should also recognize it as a storage device in the future if it works . Just play with it, took me a while....
Make sure that Applications -> Development -> USB Debugging is unchecked too.
I'm having usb errors from my laptop and it is being caused by my evo. I can connect it just fine and use it as a disk drive if needed but my windows 7 (64 bit) keeps saying that the usb device is not recognized. I tried disabling and enabling it. It's definitely the phone. Is there a special driver for android I need to install to my laptop? Any other suggestions if not?
Try deleting all the drivers and installing again. That should do the trick. Make sure you have adb drivers installed.
I downloaded the android sdk and sdk manager. Online it says there should be usb drivers but mine doesn't have the drivers. I installed all the packages and there is nothing for usb drivers. Can you or someone send me those drivers or give me a link to where i can get them for the evo? I keep getting usb errors.
Have you tried installing HTC Sync?
No I haven't. I looked it up and it syncs outlook etc. What will that do? I installed the drivers and adb and the computer still gives usb errors. It says the device connected has malfunctioned when it isn't plugged in. It's driving me nuts.
I'm pretty sure that HTC Sync installs USB drivers to help facilitate the various syncing things it does. At worst it won't make any difference, at best it might solve the problem. Can't really see a reason to not try it.
I tried it. Uninstalled and reinstalled and still getting usb errors. Any other suggestions? When I unplug my laptop sometimes i get the blue screen because of a problem with a bugcode usb driver.
I'm having a similar problem but my phone wont even with Vista on my laptop. I have downloaded HTC sync, and Android SDK, did a combo of USB settings in phone and still no luck. All my phone does it charge..how can i get it to disk?

Doesn't matter what version of Windows you're running, go to device mangler, and uninstall ALL of your USB drivers while online. Re-boot, and it should re-install the correct drivers from the internet. My USB drivers were dated 2006, before I did this! And that was in Windows 7!
Ok so I'm extraordinarily frustrated with getting this to work. I've searched the forum to the point of a headache. Something about the .inf file and hardwar id's. I've uninstalled and reinstalled the drivers a million times. I've even reflashed the stock rom. Can anyone help? usb debugging works and PTP works. Currently back to stock and all drivers currently uninstalled.

Ok, I decided to use a laptop which has never had my N7 attached to it as MTP, only as adb for wugs (before I got comfortable with doing things manually), I had the same problem you did, this is what fixed it. I had used koushes adb driver installer on it, so his driver kept intercepting it.
First I got these drivers and unpacked them: http://developer.android.com/sdk/win-usb.html#
Then I plugged in my device, with PTP enabled and updated drivers and browsed to those drivers and let it install...this did not fix it.
Disable usb debugging, plug it in, enable MTP, then go into device manager, then go into the menu and show all devices, you should see something like Google ADB driver, right-click and uninstall it, selecting delete driver checkbox, then reboot your nexus 7 while still plugged in, it should redetect your N7 as a "Nexus 7" and you should see it in Computer as a Portable Media Player, then unplug the device, wait 3-4 seconds to make sure its unmounted, then plug it back in, you should now actually see files.
NOW, once I saw that that worked, I noticed PTP stopped working, leave it plugged in, switch to PTP. then you will see the ADB driver back, uninstall it again, reboot the device leaving it plugged in, it will redetect the device again, it will say MTP again even though it's in PTP, let it finish, then unplug the device, wait a few seconds, and plug it back in, now you should be able to see it connected as a camera, and should be able to see files, now I can switch PTP ro MTP and back again with debugging off resulting in it working fine.
NOTE: USB debugging only works right in PTP mode for me.. which is fine, I tested to make sure that once debugging was off, I can unplug the device, and plug it back in and I can still switch between MTP and PTP perfectly.
EDIT: Actually I am now going to try leaving debugging enabled, in MTP mode, uninstall the ADB driver and reboot the device and see if that fixes that problem too.
EDIT2: AND IT WORKED!
So now I can have debugging on and off, in MTP and PTP mode, adb devices works perfect for either mode.
In summary, i think the REAL trick here is to put the device in each mode combination one at a time, delete the device and driver from device manager and reboot the device while it's still plugged in, then unplug the device and plug it back in, you do this for every combo outlined below, a total of rebooting and unplugging/plugging in the device 3 times...because PTP+debug on or off worked already
MTP on - Debugging off - find entry in device manager, uninstall it, reboot device, leaving it plugged in, verify it shows in Computer, unplug device, wait 3-4 seconds plug device back in, verify you can see files.
PTP on - Debugging off - find entry in device manager, uninstall it, reboot device, leaving it plugged in, verify it shows in Computer, unplug device, wait 3-4 seconds plug device back in, verify you can see files.
MTP on - Debugging on - find entry in device manager, uninstall it, reboot device, leaving it plugged in, verify it shows in Computer, unplug device, wait 3-4 seconds plug device back in, verify you can see files.
..at the end you should be able to have MTP and PTP fully working with or without debugging on.
Try installing Sony PC Companion. It will install the necessary drivers. Works great with my Nexus 7 when connecting to PC in Windows XP .
I'm on WIndows 8.1 and when I connect my N7 2013 to PC, it gives me error Unknown USB Device (port reset failed). Anybody knows how I could fix this issue?

Good luck with that.
mtp
ive had my n7 for couple months now and mtp never worked only ptp until about a week ago when in cleanrom thread here http://forum.xda-developers.com/showthread.php?t=2383146&page=389 post 3877 asked 3888 answered. I checked in android devices and did not have the android composite adb interface. so I simply unistalled the drivers I had and plugged in device and bam. working great since. don't know if it was related but the day before I updated my sdk and there were some google drivers in the update list. hope this helps someone!
I don't mind airdroid as an alternative but soooo much nicer to plug in and drag and drop!! GL!!
Finally caught the driver bug! W10 x64. Take one PC that would concurrently connect N10(Omnirom 6), N9 (rooted) and stock N5 and connect a Pixel C. Connects as a Pixel C in Device Manager under "Portable Devices" - enable USB debugging and W10 says "The last USB device you connected to this computer malfunctioned and Windows doesn't recognise it". Could write a book on the steps taken. Tried to add "Android Composite ADB Interface" via install legacy hardware and pointing to Googles USB drivers (v11) I get a no x64 compatible files error. Even cleaned out W10 driver store of relevant drivers via the command prompt ( and then discovered RAPR windows front end to pnputils.exe at https://driverstoreexplorer.codeplex.com/). Nexu5 with USB debugging + MTP connects perfectly haven't tried N9 or N10.
Any bright ideas?
Don't think this has any relevance with MTP working - Using Anker USB-C to USB3 cable with rounded edges on connectors - AFAIK this version has the correct resistor
download a copy of USBDeview for x64
open it, sort the list on vendorid
uninstall every driver with vendorid of 18d1
close the program, unplug all USB devices, reboot
make sure you have the newest google drivers on the pc
plug in pixel c and let drivers install, unplug pixel c and reboot
it should now work correctly
this routine has helped me every time i had issues with the pixel c and pc recognition
most of the steps came from wugfresh's nexus root toolkit advice on how to get proper drivers
i think what happens is drivers from other devices combine to create a situation windows can not fix so need to start over.
each device plugged in will get the install routine.
