Hi, Can you provide a usbdump trace and send it to me off-list? usbdump -i usbusX -f Y -s65536 -w usb_capture.pcap X and Y are number after ugenX.Y If you are using ISOCHRONOUS high-speed transfers with an XHCI USB controller, the XHCI is much less forgiving about the USB PIDs of the multi-data payloads coming from the USB device than the EHCI. I have seen at least one DVB-T USB adapter which is totally broken with XHCI and works just fine with EHCI. This has been verified with a USB wire analyzer. --HPS
