Can you dump all the USB commands from 10.x and 11.1 ? 1) plug device and note ugenX.Y numbers 2) unplug device 3) start "usbdump -i usbusX -f Y -s 65536 -w freebsd10.pcap" 4) CTRL+C and safe .pcap file. Repeat for FreeBSD 11. --HPS --=20 You are receiving this mail because: You are the assignee for the bug.=
