Mouse and Keyboard Stopped Working

#1
Hello

I bought a brand new MICROSOFT NATURAL KEYBOARD 4000 to replace the exact same keyboard that's a few years old. Something went horribly wrong. The keyboard and the mouse no longer work, together, individually, or combined with other keyboards and mouse.

The computer no longer recognizes the MOUSE or the KEYBOARD. Device manager shows that they're plugged in as OTHER DEVICES, but it can't install the driver for them. I've tried installing the 4000 drivers, but that's shouldn't be necessary. The installation goes fine, but still, it only shows up as an OTHER DEVICE.

The thing in common is that they are both input devices, and neither work in Windows. The keyboard works in the bios just fine. If I remove all the USB Controlleres and Ports from device manager, and reboot, the mouse and keyboard both work at the login screen until the ports and controllers are rediscovered and reinstalled, then they both stop.

Event Viewer shows things like this:

INPUT.INF exists in c:\windows\inf. I've tried manually updating the drivers pointing to that folder, but that didn't work.

It seems to me that some core piece of windows is suddenly not working. How can I fix this without reinstalling windows? Are the basic input drivers somehow missing or currpt?

I boot the Windows 7 installer from a usb drive. Unfortunately, the USB drive was C and the windows drive got pushed out to E, so I didn't want to try reinstalling that way with the letter incorrect.

Thank you for your help.

UPDATE: Other devices work in the same usb ports (ie: the flash drive). The mouse and keyboard don't work in any of the usb ports; 2 on front 6 on back.
