I have GNUradion up and running with the USRP board. I have two
cards installed. One is the DBSRX, the second is the RFX1800, and I
3rd dauther board the TVRX that is not installed. I can get the thing
respond, but I get an error on most of the python scripts. USRP Open
Interface:Usb_claim_interface: failed interface 2.
Next it tells me usrp_basic_rx: cant open rx interface.
Does anyone have any ideas? My suspicission is that the device wants
slots to be filled.
