This doesn't apply to linux-next any more. (For example,

fixed a load of stuff related to this bug since this patch was

Bernd, can you reproduce the problem on the latest tagged linux-next
branch?
I can. Still the same problem as before.

I'll try and reproduce it. I don't have the usbdux devices, but I
should be able to reproduce it with PCI devices that support comedi
asynchronous commands by removing them via the
/sys/bus/pci/devices/xxxx:xx:xx.x/remove interface. (I thought I had
tested it actually, but must have missed something!).
Was the device in use by a comedi application when disconnected, or was
it just idle?
