>       MaxPower Needed: 100mA

Eric,
The device appears non-compliant with USB 1.1 specification
for power.  Their documentation states that it is USB
bus-powered,
drawing a maximum of 100mA from the bus; yet the device can
supply up to 200mA for 16 output pins.  Add the power needed
for the 'device' and other output pins to determine what the
MaxPower should be.
IMHO the best start is to obtain a specification for the
device, detailing accessing the 8k memory, its
microprocessor, and adjusting the information that the
device did provide.  Not having a specification can raise
the difficulty of writing a driver by a substantial amount.

best regards,
gm
