"Curt" Ran in the back door and shouted

Has anyone here had any problems adding a USB 2.0 card to a system USB
1.0 system? Would you have to disable 1.0 before adding the 2.0 card,
or just add the card, load the software and connect?

Thanks,

Add the card, load software & connect.
Your PC's USB ports will still fuction as usb 1.1, the card will be the
only usb 2.0 ports.
