// Notes for the following two ION vendor-specific param descriptors:

//	1.	These have a standard USB descriptor header so they look like a
//		normal descriptor.
//	2.	Any strings in the structures are in USB-defined string
//		descriptor format, so that they may be separately retrieved,
//		if necessary, with a minimum of work on the 930. This also
//		requires them to be in UNICODE format, which, for English at
//		least, simply means extending each UCHAR into a USHORT.
//	3.	For all fields, 00 means 'uninitialized'.
//	4.	All unused areas should be set to 00 for future expansion.
//

// xC00-xFBF (length 3C0h) in the ROM.
// This structure is a superset of the v1 structure and is arranged so
// that all of the v1 fields remain at the same address. We are just

//
// The actual contents of this structure are defined in a 930 assembly
// file, converted to a binary image, and then written by the serialization
// program. The C definition of this structure just defines a dummy
// area for general USB descriptors and the descriptor tables (the root
// descriptor starts at xC00). At the bottom of the structure are the
// fields inherited from the v1 structure.
