I've just experienced a USB disconnect from the external Nova-T USB2 with the 
new firmware: the LED went out but the system didn't hang. syslog contained:

^- lots of this last one interspersed with blocks of similar messages with the 
final number replaced by -1072586294, -996626800, -863886798, -862828572, 
402659331, 0, -22, 52, etc. in a variety of orders until I rebooted.

(This is pretty much what I was seeing with the old driver + firmware but more 
often.)

Cheers,

Laz
