Hi,

today my keyboards got freezed in X (both the usb and the laptop one), the
Caps Lock LED on the laptop worked when I was hitting Caps Lock on the laptop
keyboard, but the other keys didn't work: a-Z, 0-9, F[0-12], space, .... When
I closed my X session (using the mouse) and got into the console, the laptop
keyboard worked but the USB one was still not responsive. Here are some
messages from syslog when it happened:

Note: I was plugging and uplugging the USB keyboard into the usb hub but that
didn't seem to fix the issue.

Restarting the system seems to fix this - USB keyboard works. I am using a hub
with separate power supply and have my keyboard, mouse, external disks and
other devices connected to it. The mouse works, I was listening to music from
one of the external disks, so I don't think it's a hardware issue with the
hub. I don't think it is a hardware issue with the USB keyboard either, since
this time my laptop keyboard was frozen in X.

If you need some more information, please let me know.

Thanks,
Momchil
