Re: [Discuss-gnuradio] Problem with USB on OSX?

[Jonathan Jacky]

I'm using OS X.  I've never seen this "failed to start end point 
streaming" message.   I've not used the flex 400 boards, only the Basic 
RX/TX and LFRX/TX.   Are you sure your Mac has USB 2.0 ports?   Until 
fairly recently (late 2003 or early 2004), Macs came with USB 1.1 ports.

There is more information about this 1.1 vs 2.0 business, and how to use 
the Mac System Profiler to check that OS X recognizes the USRP, at
