--- Comment #1 from Hans Petter Selasky <hselasky at FreeBSD.org> ---
Hi,

In FreeBSD there is "usbdump -i usbusX -f Y -s 65536 -vvv" where X.Y are the
numbers after ugen.

If you are using BULK, unless you clear-halt the endpoint after cancelling, one
packet may get lost due to incorrect data-toggle values at the USB wire level.
