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

but got the same error as Sam:

@ enter_search

usrp_basic_rx: failed to start end point streaming

Next I tried to use the benchmark_usb.py file and I got this error:
Testing 2MB/sec... usrp_open_interface:usb_claim_interface: failed interface 1
usb_claim_interface: couldn't claim interface
usrp_basic_tx: can't open tx interface

   usrp_tx = usrp.sink_s (0, tx_interp)

line 932, in sink_s
   return _usrp1.sink_s(*args)
RuntimeError: can't open usrp1


Interestingly, the firmware is uploaded successfully, i.e., the led
first blinks fast, then slower, and then I get the error.

Any ideas on what might be wrong?

Thomas

Thanks for the reply Jon. I'm quite sure that it has USB 2.0 ports, though.
