I am working with tinyos-2.x on tmotes on FC4. These tmotes are connected to my linux machine through a USB hub so as long as the USB interface doesn't hang it is quiet convenient to program and reprogram these motes.
There are times however due to segfaults in my code or due to simulataneous operations that my scripts perform on the USB interface (e.g reading from the flash while accidentaly programming the motes) that the USB serial interface hangs.
My question was, is there any mechanism where I can restart these serial interfaces (/dev/ttyUSB*) through software (probably a script in linux that does this) or is it only possible to restart the USB device by unplugging and plugging the motes back in.
Thanks,
Avinash
