Wouldn't seperate usb controllers have independant bandwidth? Going through a hub could be bad, unless it is one of the nicer usb 2 hubs that can deal with multiple usb1 devices efficiently (I think I read some can do that). A 4 or 5 port usb card isn't expensive after all. Len Sorensen -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
