ah yes,

I remember this problem at the installfest.

From what I know about it, the problem was that his system would not
create the device nodes, and it could not be mounted.

I think there was also more complex problems though, and simply creating
a device node didn't work...


When plugged into anyone else's system, the device worked. When we tried
it on mine, the device was detected, and we could also see it with
'fdisk -l'.

On Donald's machine this command showed nothing, which is strange, as
this command doesn't depend on device nodes existing from my knowledge.


Donald, has this card reader ever worked on this pc, under any operating
system? (ie: Windows, or older Linux version?)
