Hi, I have a Dazzle Fusion flash card reader that seems to function normaly. It reads and writes to flashcards fine, however it completely crashes (system only responds to Alt + Sys Rq + b) Hardy when i disconnect it. I didn't have this problem in gutsy. I was wondering if there was a way to disable it before I unplug it, similar to unmounting a drive?

I have had hardy lockup randomly even when not unplugging it, does the usb driver refresh somtimes?
