I tested your diff with the following device: uaq0 at uhub0 port 19 configuration 1 interface 0 "QNAP QNAP QNA-UC5G1T USB to 5GbE Adapter" rev 3.20/1.01 addr 4 uaq0: ver 2.5.30, address 24:5e:be:xx:xx:xx I noticed that if the device connects to an xhci controller and connects to a Gigabit switch, I'll get a bunch of messages while running iperf3: uaq0: offset mismatch, got 5232 expected 49969927280 uaq0: offset mismatch, got -25912 expected 149128480565874 uaq0: offset mismatch, got 2192 expected 55976167568 ... Apart from that it's working fine. > ok? ok kevlo@
