No, we do not support Atmel USB sticks, nor we do not have plans for
adding support
for it in the foreseable feature. However if the onboard ATmega can be
programmed to
provide usb-serial interface, one can use/adapt our serial discipline
driver to control it.
One will still have to write firmware for the on-stick ATmega chip.

Or you can add support for any existing interface that is provided by
RazorUSB card by yourself.
We tried to make mac802154 drivers easy to implement.

Hmm. One can solder (e.g.) the FTDI 2232 together with AT86RF230/231
and use that combo
instead of RazorUSB sticks.

I'll look for the interface they are using to control sticks and check
how easy will it be to
write a driver for it.
