Greg,

When I unplug the USB device with the driver loaded, I get the following BUG and 
my laptop freezes:

kernel: BUG: unable to handle page fault for address: ffffeb0200043248
kernel: #PF: supervisor read access in kernel mode
kernel: #PF: error_code(0x0000) - not-present page

The traceback points to a kfree() call. I do not understand this BUG. Can you 
explain what happens?

I think I know how to avoid the BUG, but that might be at the expense of a 
memory leak.

Thanks,

Larry
