Josh,
 Trying it out on one of my USRP2's here, with an RFX2400. The build
went well: libuhd, firmware and fpga images all built fine. And
building the gr-uhd branch of gnuradio had no problems either,
although I haven't gotten to the point of being able to use it yet:  I
seem to be having trouble with the USRP2 registering as being found.
For example, if I run uhd_find_devices, I get:

> $ uhd_find_devices
> No UHD Devices Found

Opening up wireshark, I can see that the host and USRP2 are
communicating over UDP (with the correct IP addresses, it seems to me
at least):

> 43    14:56:36.672264    192.168.10.1    192.168.10.255    UDP    Source

> 49152  Destination port: 40243

Host has the IP address 192.168.10.1 on the interface connected to the
USRP2, and the USRP2 appears to have the default 192.168.10.2. I can
send the contents of the UDP packets if you'd like to see them.
Taking a quick look at the usrp2::find function, it looks like it's
supposed to be waiting in a while loop until a timeout occurs, is it
possible the timeout is happening before the response came from the
USRP2? Or have I perhaps made some simple mistake?
 Thanks,
  Doug
