Jiri,

I have enabled USB debugging and I see a bunch (=46) of these messages:

   [  $timestamp] usb 1-9: usb auto-suspend
   [  $timestamp] usb 1-9: usb auto-resume
   [  $timestamp] ehci_hcd 0000:00:02.1: GetStatus port 9 status 001005 POWER sig=se0 PE CONNECT
   [  $timestamp] usb 1-9: finish resume

The messages continued to be logged, even after the keyboard has
become unresponsive.

The entire kernel log is at http://iucha.net/usb/log-2.6.23-rc3-2 .
The dump of /proc/bus/usb/devices is at http://iucha.net/usb/devices .
The output of 'lsusb -t' is at http://iucha.net/usb/lsusb-t .  Plain
lsusb is not working.  The version of usbutils is '0.72-7ubuntu2' .

Do you need me to build a -rc2 with USB debug enabled to compare and
contrast?

Thanks,
florin
