Yes, as Leif says, the unit works just fine as a passthru device.  I
already have it working with my own SDR program.  It supports TX as well,
though I haven't tested that aspect yet.  I doubt I'll make use of the FPGA
personally; while cool, I want my program to be compatible with "dumb"
devices like the the RTL units and so there's not a lot of value in
special-casing the bladeRF.
