Hey gang,
I've been using the USRP without GNURadio from time to time, just using
libusrp to talk to it. Yesterday, I had some cabling problems and
couldn't get my signal close enough to the USRP. To compensate, I
moved the USRP closer to the signal by using two USB cables and
hub. I noticed that my signal processing apps weren't working any
more, but the usrper app was still able to do "usrper set led0 on" type
actions. Does anyone know anything about the USRP or USB that
would cause this behavior? Specifically, I believe the error I
was getting was on the call to create/init the usrp_standard_rx class
(or whatever it's called).
