[Solved]: See the bottom.
Hi. I upgraded my kernel from 3.4 to 3.8.13. Then my USB keyboard does not work, although detected; i.e. key touches are ignored. It's already in consoles, not only in X. (X server also detects it, but xev doesn't report key punch events.) Other USB devices and the built-in keyboard (it's a notebook pc) do work.
The output of dmesg doesn't differ much; the driver has changed from "generic-usb" to "hid-generic", but I doubt if that matters. (All changes are hilited. These are the only related messages for this device.)

One peculiar thing is that sometimes for the first seconds after connection key punches are correctly echoed. I'm clueless.
Thanks for reading. Regards.
Edit:
Sorry, it's due to my custom script.
I used to set /sys/devices/.../power/control to "auto". It's ok for previous kernels, but with 3.8, the keyboard gets unusable. |
