Hello,

the lovely folks from #kernelnewbies suggested I write this mail since
they are at a loss.
I recently got a new USB keyboard which works fine in the BIOS and also
in VBox Windows guests, but not on the host.

The keyboard is a Keysonic KSK-8003 UX product details here:
http://maxpoint.de/de/products/keyboards.php?pid=1_3_7&we_objectID=1220

The menu key and the backspace keys do work. The num lock led is on,
though I can't switch num lock off.
If I attch the keyboard to a VirtualBox VM running WindowsXP as a guest,
it works as expected in the VM.
This indicates that it is working on the USB level.

I'm running 2.6.32-27-generic #49-Ubuntu. I tried the Ubuntu 10.10
LiveCD and that also didn't work. I haven't tried 11.04 yet though.
Do you get anything on the event device? What does udev say when you
plug in the device?

...

one thing I found out is that this keyboard has some special anti
ghosting function for some keys. Where you can press multiple keys
simultaneously
and they are all recognized. This is apparently great for gaming. Which
I'm not interested in...

Something else that might help is a usbmon trace showing what happens
when you plug in the keyboard.  Instructions are in the kernel source
file Documentation/usb/usbmon.txt.  In particular, while running the
test try pressing some of the normal keys that don't work.


The attached file usbmon-working.out is the output when I pressed the backspace key. When I press any of the non working keys which is everything but the backspace and menu key. I don't get any output even when using 0u.

Also, it would help to see the output from "lsusb -v" for this device
-- but you'll have to unbind it from the usbhid driver first.


When attaching the keyboard I get 2 devices in
/sys/bus/usb/drivers/usbhid/2-1.1:1.0  and
/sys/bus/usb/drivers/usbhid/2-1.1:1.1

The output is in the attached lsusb.txt.

Cheers
