Yes, perfectly. To reduce the number of USB interactions, it will
probably make sense to introduce an intermediate layer that handles
slightly more complex operations, and implement these operations in
the atusb firmware, but that's an optimization.

As a first step, only register and buffer access will be sufficient.

The linux-zigbee project [1] has alredy implementd a partial stack,
including a - somewhat simplistic - driver for the AT86RF230. So
that should be a good starting point.


The project's kernel repository is somewhat misleading. A new set of
patches (for 2.6.38) has been posted to the project's mailing list
just a few days ago:
