I'm not sure if that's necessarily related, but the device only seems to fa= il under large TX, not RX. A few other notes: 1. ugen0.1 refuses to come up to superspeed, even under Linux - this may ju= st be an issue with early revision boards. I intend to avoid using this bus entirely for now. 2. I was able to get the bus and devices up to superspeed hanging off of ugen1.1 under Linux _sometimes_ but only once I disabled powersaving on everything. --=20 You are receiving this mail because: You are the assignee for the bug.=
