Eh, that info is already trivially available from my original mail: uhci_hcd 0000:00:1d.2: new USB bus registered, assigned bus number 3 [...] input: USB Compliant Keyboard as /class/input/input0 input: USB HID v1.10 Keyboard [USB Compliant Keyboard] on usb-0000:00:1d.2-1 input: USB Compliant Keyboard as /class/input/input1 input: USB HID v1.10 Device [USB Compliant Keyboard] on usb-0000:00:1d.2-1 > Do you have the device attached before turning on the machine ?

Will include that in my reply to Alan's mail.
