Hi Gianluca,
the crash / freezing occurs before disconnect in normal operation.
So the patch will not solve this problem.

The driver is working but after some time the system crashes and does
not react any more.
Just doing the simple test "rtl_test -s 3.2e6".
Hi Karsten,
this patch should fix the system crash after disconnecting the USB stick:
