\ Sun adds ability to detect keyboard country from HID descriptor
\ for Sun type 6 and type 7 keyboards. This capability will be lost
\ in type 7c keyboards (which no longer have a country code), but
\ we still have to support existing hardware.
\
\ We read the HID descriptor from the interface. See HID device
\ class specification, from:
\ http://www.usb.org/developers/devclass_docs/HID1_11.pdf
\ Section 6.2.1 HID Descriptor defines this structure. Offset
\ 4 (listed as 4/1, offset 4, one byte long) is the bCountryCode
\ which this routine returns.
\
\ This method gets called infrequently, so we do our own alloc/free
\ rather than doing a top-level alloc/free like kbd-buf.
