Just three? The EHCI controller reports there are three more busses in addition to EHCI ... you showed one UHCI, I'd expect there would be two more. (Each UHCI bus having two ports, and the EHCI one having six. I'm guessing this is an Intel controller; it doesn't look like VIA since the size of the periodic schedule is fixed at 1024 entries, it's not tunable.) > Coincidentally, > or not, the bus on which the drive works is the one whose jacks > are directly soldered to the MB, that is, the ones right next to > the serial, parallel, mouse, KB, ethernet, etc connectors at the > back.

The motherboard connectors I've seen were easy to hook up backwards, or even just offset by a row of pins or two. And some of those cables didn't seem to handle high speed signals all that well, either. Since you're seeing catastrophic errors very early, a wiring problem like that could explain everything... - Dave ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
