What happened ?

When issuing read() to provoke timeout the device becomes unusable. It does not respond to new commands anymore; needs to be power cycled.

How to reproduce ?

Issue read() without prior write(). The command will timeout. Trying to do a clear() with result in endless messages from host to device without positive result ; i.e. any new command results in timeout. See log files for steps to reproduce.
