Bug#248855: Useful clues for non-working USB keyboard on SunBlade 150 / sparc64

[Frans Pop <aragorn@tiscali.nl>]

Here's a corrected patch for alternative 2: s/usb/hid/ :-(

I also found some references that actually support patch 1:
- bInterfaceClass is defined in
  http://www.usb.org/developers/defined_class
- bInterfaceSubClass and bInterfaceProtocol are defined in
  http://www.usb.org/developers/devclass_docs/HID1_11.pdf
  (see pages 18 and 19, i.e. page numbers 8 and 9)
