Hi Leon,

I've attached a bash script that does waht you're trying to acheive 
(sort of, you'll need to cut to size...)

This just watches the list of FW devices as reported, and reports 
whether our specific device is available or not.

It requires one command parameter, the GUID of the device.

Regards,

Euan.
