Same as my > previous report. http://pastebin.com/pVD3B4YZ In fact, the usbmon trace shows no information about the keyboard at all, although it does show input coming from something that looks like either a keyboard or a mouse. For doing these tests, it's best to begin with the keyboard unplugged. Then start the trace, plug in the keyboard, and stop the trace a few seconds later. Don't do anything else while the trace is running. Want to try again?
