Windows 7: Mouse Help

I have had windows 7 x64 for a while and suddenly, my USB mouse (OCZ Behemoth) stopped working. oddly, only the pointer stopped working, the clicker and scroll wheel work fine. It's a corded mouse, so no "new battery" comments.



WHAT I HAVE TRIED

• Different port
• Device manager->Reinstall (it appeared as "Unknown USB device". it now appears as "USB Human Interface Device" but still does not work.)
• Rolled back using System Restore to yesterday when it worked, nothing.
• Rebooting
• Going into my WinXP x64 install, it works there
• putting the Behemoth in my laptop, it works.
• Using another USB mouse on my computer (doesn't work with 3 mice that work fine on other computers)
• Trying other USB devices in my ports (all ports work fine with a thumb drive, as well as USB devices that require power)

POSSIBLE CAUSES

• I recently set up a "guest" account on my computer. this is the only major change i can think of (this was removed when i used System Restore)

IT IS NOT

• Motherboard Drivers (USB works fine with other devices)
• OCZ drivers (no mouse works correctly)
• Mouse Battery (corded mouse)
• Bad install (it worked fine for the approximate month i had Windows 7 on my computer)
• Proprietary driver clash (self-built rig, not HP/Compaq/whatever)

NOTES

• I have not tried a PS/2 mouse or USB->PS/2 adapter because i do not own one.
• The "new hardware wizard" does not pop up upon a mouse insertion
• I am admin account

I read in another forum that for some reason, this mouse can be disabled by pressing the caps lock button twice too quickly. I had the same problem as the original poster, and was disheartened when my roommate called to tell me that the mouse had stopped working. I read some forums and found this fix. Windows had been reading the mouse as "malfunctioned" and would not install it after disconnecting, replugging, and restarting. Anyway, this did it and my mouse is good as new. OCZ must have had some crazy design thoughts when they designed a mouse with an automatic feature to disable the mouse without telling anyone
