Hello,

I use the stable kernel tree 2.4 and have reproduce the following bug
with 2.4.36.2 and 2.4.36.7.

I got a new barcode scanner and plugged it into USB. The scanner works
well until I remove it. In that second I get a trace and the kernel
freeze.

The message when I plug in the scanner:
 hub.c: new USB device 00:1d.7-6.2, assigned address 5
 input: USB HID v1.10 Keyboard [Weltrend Bar Code Reader] on usb1:5.0

The message when I unplug it:
 Unable to handle kernel NULL pointer dereference at virtual address 00000048
 ...

Please pardon that I do not type the complete kernel dump as I know no
way to log it to a text file in this case where the system freeze. But
on request I can send the picture I made with my camera.

Regards
   Klaus Ethgen
