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.

One can solder (e.g.) the FTDI 2232 together with AT86RF230/231 and use that combo instead of RazorUSB sticks. > freaklabs.org is using ATAVRRZUSBSTICK 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. -- With best wishes Dmitry
