Sorry for the 'shock horror!" subject to this post, but I've never had knoppix lock completely on me before, the mouse pointer freezes and ctrl-alt-F1 doesn't work, only pressing the reset button.

The device that does this trick is a PQI smartmedia flashcard reader/writer which I'd read was supported and working. It's based on the Alcor AU9350xxx chip (I popped the lid) which claims to be USB bulk storage compatable. I have no idea where to start, I cannot even look at dmesg or use any of the USB commands.....

I checked it on the same PC/port in W98SE (I was that desperate!) and it seems fine, so it's not a hardware issue.

I've used other USB flash reader/writers without problems.

Any ideas? - even how to get some sort of log message?

Thanks.
