Prices are good and they are still available. I had a quick look at their schematics in the user manuals: http://freaklabsstore.com/pub/FREAKUSB-900MHz%20v1.1%20Datasheet.pdf http://freaklabsstore.com/pub/FREAKUSB-2.4GHZ%20v1.1a%20Datasheet.pdf They use the at86rf231 and at86rf212 transceivers (I still hope for a 215 device) The problem I see is that USB is connected to a FTDI usb serial bridge chip instead directly to the Atmel MCU. I have no idea if the FTDI can be swichted into a passthrough mode. If that is the case re-using the existing atusb firmware and USB protocol to the kernel driver should not be to hard for someone interested. If the passthrough is not possible and the whole communication protocol has to go over the serial line that would be significant more work. Adapting the protocol over a serial line, adapting firmware and adapting the kernel driver. Doable, but significantly more work compared to say the hulusb support in ATUSB which have been added recently. If someone wants to poke at this I would be happy to give some guidance. regards Stefan Schmidt -- To unsubscribe from this list: send the line "unsubscribe linux-wpan" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
