[Discuss-gnuradio] Problem with RFX1800: "No class defined to handle daughterboard"

[Martin Schobert]

Hello,

  I have an USRP rev4 and tried to use the RFX1800 tranceiver with  
the usrp_oscope.py example program under Ubuntu on a PC. My CVS / SVN  
checkout is two or three days old. I own a RFX2400 tranceiver, too.  
The RFX2400 works out of the box, but if I plug the RFX1800 on the  
USRP I only get this error message:

usrp_oscope.py -R A

How can I fix it?
