Description of problem: We have a Dell Chicony USB keyboard (model KU-9985) which fails to work when plugged in. There are ugly messages in /var/log/messages, and "lsusb" will hang. It turns out that this keyboard says that it has both a keyboard and a mouse, though there really is no mouse at all (no PS/2 port, no mouse). When Linux issues a "get_report" for the mouse reports, the keyboard stalls, and things go downhill. This keyboard works fine if we add it to the blacklist with the "NOGET" quirk. Version-Release number of selected component (if applicable): How reproducible: Very easy. Steps to Reproduce: 1. Boot up system. 2. Plug in KU-9985 Chicony usb hub keyboard. 3. Actual results: Keyboard doesn't work, there are ugly messages, and "lsusb" will hang. Expected results: Keyboard should work, lsusb should work normally. Additional info: I will attach the patch.

Vojtech accepted this but did not notify me. I'm going to post this to review in a few hours. U2?
U2 is fine. Thanks!
