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.
