Jiri, I have enabled USB debugging and I see a bunch (=3D46) 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 POW= ER sig=3Dse0 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?
