I'm not sure why you think the laptop has a USB keyboard. According to your log messages, it doesn't. As you can see in the message quoted above, it is an "AT Translated Set 2 keyboard", connected to the i8042 keyboard controller. Not USB. In fact, the lsusb output attached to the Ubuntu bug report shows only two USB devices on the computer: a flash drive and a Bluetooth dongle. No keyboard. This bug should be reported to the linux-input mailing list.
