Sample Descriptors
Tables 21 through 33 are the lists of sample descriptors for mouse, keyboard, and com-
posite device implementation example. Note that the these descriptors are provided for the
peripheral implementation reference purpose only, and DO NOT GUARANTEE the com-
plete performance of the actual peripheral devices.
Please also note that the idVendor is vendor specific parameter. In this table, idVendor is
set as
SHARP
for our convenience.
