Here is my setup:
OS: Ubuntu 8.04
USRP1 with 2 LFRX and 2LFTX daughterboards

I primary use the USRP as a 4 channel Digitizer and have been running
gnuradio-3.1.3 without any problems so far. To test 3.2rc2 I tried
running the multi_fft.py which is available in the
gnuradio-examples/python/multi-antenna/ directory. I commented out the
portion which checks for the the number of channels available and the
daughterboard ID since I didn't have the BASIC_RX. Here is the major
change that I found.

The value of len(self.subdev) = 4 in 3.1.3 and =6 in 3.2rc2.

Shouldn't this be 4 as it was previously?
