 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
