help! i have been upgrading the 7600 one upgrade is a usb card . it does not seem to work.

i started with a belkin card that was usb 2 so i removed it and put it in the g4 dual which works perfectly.

i also have a dh-pc4 card.

it does not work either i have tried a mac pro mouse. and nothing happens.

also system profiler dies with error 10 when you quit with the card installed. [] ]'>
