I'm now doubting: reading back the thread, you mention an esv14+
but the msg title is about an evolution.

if it's the former, stay with mge-utalk.
if it's the latter, go with mge-shut.

Is there anyway I can test whether the problem is to do with the USB

it's quite possible, since I've seen iirc some issue when the converter is
attached to a hub that is not a root one.
so, is the converter attached to a root hub (ie directly on the PC)?
