I've gotten myself into a bit of a quandary. I have a Windows 7 x64 computer with USB 3.0 ports. I installed some specialized camera driver software (Point Grey's FlyCapture 2) for use with a high-end USB 3.0 camera.

During installation, there was a option to install a new USB 3.0 driver, with a warning that non-Point Grey devices would no longer work. I (stupidly) ignored this, as I thought my keyboard/mouse were on a different (i.e. non-USB 3.0) interface.

I was wrong. Now when I load Windows, I get to the user log in screen and neither keyboard nor mouse works. (Interestingly, if I turn off my computer without letting Windows shut down properly, I get the text screen asking whether to boot Windows normally or in safe mode -- and in this screen my keyboard works, allowing me to choose which option with the up/down/enter keys.)

So my question is: how do I restore the default USB drivers to get my keyboard/mouse working again?

No modern PC just has USB 3.0 ports- there SHOULD be USB 2.0 ports either on the rear or in the front panel – Journeyman Geek Feb 18 '13 at 0:36
So have you tried Safe Mode? If they work there you can uninstall the new driver. – Karan Feb 18 '13 at 0:58
@Karan - yep, tried Safe Mode, with the same problem: mouse/keyboard not responding. – Ghopper21 Feb 18 '13 at 1:12
@JourneymanGeek - yeah, that's what I was thinking -- that my mouse/keyboard (via a Logitech wireless dongle) was connected to the USB 2.0 port, not the USB 3.0 port. Alas, not so. I tried with the dongle -- and other, normal wired mice -- on the USB 2.0 port, with the same non-responsive behavior. – Ghopper21 Feb 18 '13 at 1:13
Are you able to access the boot options and/or BIOS? – HodofHod Feb 18 '13 at 1:37

Here's how I fixed this:

  1. Went to my computer's BIOS setup
  2. Disabled the USB 3.0 ports
  3. Plugged the mouse/keyboard into the USB 2.0 ports
  4. At this point, Windows started normally
  5. Opened a command prompt and used rstrui.exe to restore Windows to the state before I installed the new USB 3.0 driver
  6. Re-enabled the USB 3.0 ports in the BIOS setup
