Hi All,

I am using TelosB motes running theTOS 2.0.1.

I installed the BaseStation app and started SerialForwarder to start writing
to the mote. In all the cases the writes were successful and the only write
failure was when I tried hogging the mote with the writes. The writes would
continue successfully when I stopped hogging.

But, in very rare events I see the "write failed" event used to trigger and
all subsequent writes would fail after this even though the D20 green serial
led would blink indicating that the packet has been received. This happened
even when I am not trying to hog the mote. In that event I plugged out the
mote ,re-plugged it, restarted SerialForwarder and started serial writes
again successfully.

I tried finding the way in which we can stop the mote from the laptop if the
writes fail. But, I think it is not possible to switch off the USB power
from the SW level. Let me know what could be the possible problem in the
mote.

 I thought of removing the modules usbserial, and ftdi-sio would help by
issuing:

$ rmmod ftdi-sio
$ rmmod usbserial

But, this will only remove the modules from the linux kernel and the problem
in the mote may still persist and will come again when the modules are
loaded again.

Any guesses?

Regards
