Re: [Discuss-gnuradio] "pipe is stalled" (OSX)

[Michael Dickens]

Those are all normal for running USB on OSX using LIBUSB 0.1.X.   
Sometimes you get those errors, and sometimes you don't ... depends on  
many parameters, and I've never found a correlation -- though  
admittedly I haven't tried very hard ;)

From the printout of "usrp_print_db.py", it looks like your USRP is  
correct attached and GNU Radio installed correctly.  Yay!
