USB power while PC is off
SoundDoc:
I'd give your motherboard manual a quick check over as well to possibly solve this before you start hacking up cables and such.
Most motherboards come with jumpers for each USB port to be either powered via Vcc or Vsb.
Most motherboards I've come across in the last year have started by default to have the rear ports jumpered for power on standby so that mouse movement, or USB keyboards can wake them up.

I'm running into a similiar problem, using a mini power minder. I had to switch to a new motherboard and can't find the option to disable the USB power. The motherboard is a DFI N2 Ultra A.

If you want your mouse to not have power, you need to use the PS/2 port. (Most USB mice come with a USB to PS/2 adaptor, so shouldn't be a problem, yah?)

I don't see any jumpers in the manual. If it's not a BIOS option, then you probably can't disable the USB standby power. Check the power settings in the BIOS to make sure. It might be listed as a "wake up" setting of some kind.

Not a mouse issue. The power minder uses the USB port to check voltage, and when it detects none, it shuts off everything connected to it. Worked great on my AN7.
I didn't find anything in the manual either. I'll have to go through the BIOS with a fine tooth comb again.
