After connecting Creative Optical Mouse:
hub 1-0:1.0: new USB device on port 2, assigned address 2
usb 1-2: config 0 descriptor??
Then I've run 'lsusb' (lsusb (usbutils) 0.11), it showed some
output. But kernel oopsed silently. I found in dmesg:
usbfs: process 1366 (lsusb) did not claim interface 0 before use
Unable to handle kernel NULL pointer dereference at virtual address 000000c4
printing eip:
d0a7726d
*pde = 00000000
