Hi,

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.
