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
