Hi-

What kinds of hid devices do you have?
Can you post 'lsusb' output (from usb.in.tum.de/download/usbutils/
if you don't already have it)?

I suspect that the hid_types array index is invalid, but you
could be right -- maybe the hid ptr is invalid.

Please try the attached patch and let us know if it helps/works.

Since I was just looking at this, I am familiar with this oops.
However, normally you should run Oops messages thru ksymoops
so that we can read them. :)
