Sounds good. If you want to email me directly I can see if I can fit it into the current project, or even see if I can work with the original wpanusb author. > > Lastly, I feel like this is a recurring question, but a number of us > > will likely need a bunch of 802.15.4 USB dongle to speak to our 15.4 > > nodes.

Excellent! I also found this which seems like it should be supported (with something out of linux-firmware maybe?) http://www.ti.com/tool/CC2531EMK C
