Subject: [PATCH] * Add a quirky device entry for XBOX 360 controllers. * As
 they don't claim to be HID, they don't provide a report descriptor either,  
 so we build one. The built descriptor is similar to the one found in FreeBSD 
  for the same class of devices. Might fix/help #7649, for lack of hardware I 
  can't test this.
