The most easy way to know this for sure, is to check the real data
traffic using usbdump:
usbdump -i usbusX -f Y -s 65536 -vvv
My guess is there is some data toggle issue, and that the USB stack
tries to clear some error using a clear-stall command, which possibly
your device does not handle properly.
