While this is true, the USRP1 also did not need to be reloaded every time
unless it was power down. Apparently the 3.2.2 load is not the same as
the one for UHD.

Sure, after the GnuRadio user finds and installs them. I want to look
at signals and munge some bits, not learn installation intracies.

So why is the old firmware not okay? Up until sdcc was 'upgraded' to
3.0, the USRP1 firmware was built and installed by gnuradio. The user
did not have to find anything on websites or specify the file unless
it was other than the default.

Interesting that it claims to have found the .rbf file in a place where
it does not exist. :)

Why does uhd_find_devices install one file and not the other?
