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.
