Best I can tell, the clone of UHD contains the std_2rxhb_2tx.rbf and
std_4rx_0tx.rbf file (and others). No .ihx file, though.

I seems to either be different or UHD can not determine that it is the
same. UHD wants to re-load the USRP1 even when I move the USB connector
from an older machine and dmesg shows it to be loaded with the FX2 code.
Might get re-loaded when moved the other direction but the old code is
not as obvious about it.

No problem. I'm just trying to get it to work with the 3.5.+ stuff so I
can take advantage of new examples. Instead I'm learning Ubuntu, cmake,
UHD, and various install intricacies.
