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

[Jan Schiefer]

Hi Thomas,

I am using gnuradio+USRP on a MacBook Pro under 10.4.7, this setup 
should be very similar to yours.I have a version 3b USRP, with a BasicRX 
and a BasicTX board.

Have you checked out http://comsec.com/wiki?UsrpInstall ?

When I plug the USRP in my system, before it loads any firmware (i.e. 
before I run any usrp-related program), I see the following in the 
System profiler (Apple logo/About This Mac, click More Info... , 
Hardware/USB, USB High-Speed Bus/Vendor-specific
Version 0.02, etc etc Product ID 0x0002, Vendor ID 0xfffe.

After running test_usrp_standard_tx, this information changes
From "Vendor-specific" to "USRP Rev 2", the version changes to 1.02 and 
there is a "serial number" string of all zeroes.

Does yours show the same information in the System Profiler? Also, what 
does it say if you go to the usrp directory and run a "svn up"? Mine 
says "At revision 832."

Cheers,
  Jan
