New USB Device Drivers Fail to Install
I have a problem with my laptop, which is a Dell M4800 Precision running Windows 7 x64 Pro.
What happens is whenever I plug in a usb device (keyboard, usb stick, usb floppy drive, etc) that this computer has not seen before, windows fails to install the device, stating that it could not find the device driver. Oddly enough it works fine with devices it has seen before some date in the past, such as my wireless mouse, all of my usb sticks, and my external harddrive.
If I plug a previously seen device into a port that it has never been in before, I get the same symptoms.
Looking up the failed device in device manager shows it with a code 28 (The drivers for this device are not installed.)
Stuff I have tried so far:
- Updated the intel usb 3.0 extensible host controller drivers from Dell's website.
- Ran the sfc /scannow command in a command prompt running as administrator. It stated everything was fine.
- Followed every step in this guide (deleting INCACHE.1, etc): USB Driver - General Fix for Problems
- Attempted to do a system restore, but the earliest one I had was from the 29th. Same problem when I restored to that state. I undid the restore.
- Uninstalled everything under the usb devices in device manager, then rebooted. Windows was then unable to install virtually everything that used to be there. Had to restore the system to a point I made before attempting this so I could get back to at least using the known devices.
- Transplanted the C:\Windows\inf directory from a known good machine (my desktop) to this laptop with no avail.
- Created a system repair disc using the windows utility, then rebooted and ran it. The repair utility said it found no issues.
I've been fighting this problem for the last few days, and everywhere I look, it looks like the solution was to reinstall windows. I hope I don't have to do that.
Anyone have any ideas?
