I'm having a few problems with my Nova-T-500s - they seem to (fairly
frequently - at least once a day) cause a kernel OOPS. This seems to be
(most directly) due to a USB disconnect - I've attached the dmesg
output. Any ideas on why this USB disconnect is happening, and should
the drivers be handling this any better?
Cheers,
Robin
