USB HID port

>Can the ARMmite board and your BASIC be used to create/construct a HID
compliant PC input device?

>I don\'t see any commands for the USB port. Is the USB port simply used for
programming?

The ARMmite uses an FTDI 232R chip. It identifies itself as a serial device to
the USB. Whether that can be changed is a question for FTDI (but my guess is
not). In the ARMmite the USB port acts as a serial channel for programming and
for communication from your program to the PC.

The SuperPRO has builtin support for USB. It would require an additional
crystal to be added specifically for the USB clock. There are pads for that
crystal to be added.

As for software, you would have to adapt software from NXP's driver library (it
won't be a built in function in BASIC or C)

This looks like an interesting device, MCP2200

It enumerates as both a HID and a VCP (virtual com port).

Any interest in boards that would use this? I'll get them built, but can't do
much support beyond that right now.

If it truly is plug and play with the standard Microsoft drivers, then we might
switch over some day.

Not the IF above is a really big IF. The best thing about the FTDI part is it
has been pretty bulletproof, and its drivers just seem to work with very few
service calls.
