probably not, but rather, i think the isub likes to be attached to the cube itself, and not a usb hub. there's latency in usb audio, and even though the isub is self powered, i can imagine that the problems you are experiencing are due to usb audio deficiencies. even if it's inconvenient for you to do so, do a trial with the isub connected to one of the usb ports on the underside of the cube and try doing all of the things that you mentioned in your email where things went wrong. --alan On Sunday, January 5, 2003, at 10:27 AM, Therain Demon wrote: > Is it 10.2.3, or is the iSub defective? >
