Re: [avr-gcc-list] at43USB355 HID

[Keith Gudger]

Steve:

You say you want to "read" from the board, and you put data in the "OUT"
endpoint.  Usually a read *from* the board is an IN transaction, not an
OUT transation.  Does you VB app follow the example VC app in the
distribution kit?

If you want detailed help, I am happy to give you any I can.  Please email
me off the list, as I don't think this is a "general discussion" topic.
