These adapters allow pre-USB Sun keyboards to be connected to USB-only machines, but include the wrong maximum keycode in their report descriptor, making most of the keys present on Sun keyboards but not 101-key PC keyboards nonfunctional. This patch implements a quirk that overrides the maximum keycode in the report descriptor.
