Today I've tried to upgrade from 3.1.6 to 3.2.1. I did not change 
anything else only the options mentioned below

After that my mouse stopped working in X (yes, evdev emerged after the 
kernel upgrade).

I had the following errors in my log

Feb 22 17:17:55 brutal kernel: logitech-djreceiver 0003:046D:C52B.0003: 
claimed by neither input, hiddev nor hidraw
Feb 22 17:17:55 brutal kernel: logitech-djreceiver 0003:046D:C52B.0003:

Feb 22 17:26:20 brutal kernel: logitech-djreceiver 0003:046D:C52B.0007: 
logi_dj_probe:hid_hw_start returned error

Do you have any idea?

Thanks
Laszlo
