• Win 95 Plug and Play ID fields

For compatibility with the old serial mouse

drivers, all mouse-compatible pointing de-

vices must restrict themselves to a 6-bit char-

acter set, for all fields except the mouse ID.

Therefore, all old-mouse-compatible strings

are limited to values of 0×00 to 0×3f; character

strings are ASCII codes from 0×20 to 0×5f,

offset by subtracting 0×20.
