Having a technology breakdown weekend.... my new usb soundcard does not like my Belkin powered USB2 hub... it crackles and hisses, and eventually fails, but works fine if connected directly to a usb port on the Shuttle. I could never get my gyration mouse to work properly through the hub either... time for a new one I guess. So is there much to usb hubs? I need it to be self powered, and only really need four ports, but it needs to run each device consistently and not conflict with the other devices plugged into it. Any ideas? thanks lisa EDIT: don't worry - think I might have fixed it!
