rtwn0: detached
Hi,
Likely the device's firmware crashes/restarts and the device detaches.
Maybe you can do a usbdump of all traffic, to isolate exactly which
command causes this.
usbdump -i usbusX -f Y -s 65536 -vvv
X and Y are numbers after ugen.
Run
Part of the usbdump below around the point it detaches and starts logging
ERR=IOERROR rather than ERR=0
