Use the blocks in the UHD category (not USRP). Also, the floating point
samples are between -1.0 and 1.0 which is different than the old driver,

Both channels should work. Configure the single usrp block for two
channels and setup the subdevice specification string (should be docs
for this in the block properties dialog box).
