https://wiki.freebsd.org/FreeBSD/arm/Raspberry%20Pi makes it look like both USB and the NIC could come up easy.

The first step of this one could be to get the Graphics Toolkit into the RSB. Then leave USB UI devices as bonus work. Based on history, I expect that putting it as bonus work and after those tasks means it will be unlikely to be worked on anyway. >> --joel >> >> >> On 3/16/2015 1:59 PM, Yurii Shevtsov wrote: >>> Is there any final list of items?
