Ok, it's working again. I had to rebuild libusb after a kernel upgrade. The 
usrp example script files run fine now. It seems to perform better than 
previously. This prompted me to run the benchmark_usb.py script, which 
unfortunately fails with the following message:

husky: {113} ./benchmark_usb.py
Testing 2MB/sec... TX d'board A: Basic Tx
usb_control_msg failed: error sending control message: Input/output error
TX d'board B: <none>
open_nth_cmd_interface: open_cmd_interface failed
usrp: failed to load firmware /usr/pkg/share/usrp/rev2/usrp_firmware.ihx.
Traceback (most recent call last):
  File "./benchmark_usb.py", line 106, in ?
    main ()
  File "./benchmark_usb.py", line 96, in main
    ok = run_test (rate, verbose)
  File "./benchmark_usb.py", line 66, in run_test
    usrp_rx = usrp.source_s (0, rx_decim, 1, 0x32103210, 
usrp.FPGA_MODE_LOOPBACK)
  File "/usr/pkg/lib/python2p3/site-packages/gnuradio/usrp.py", line 98, in 
source_s
    return ((usrp0_source_s_stub, usrp1.source_s)[look_for_usrp(which)])
(which,*args, **kwargs)
  File "/usr/pkg/lib/python2p3/site-packages/gnuradio/usrp1.py", line 1250, in 
source_s
    return _usrp1.source_s(*args)
RuntimeError: std::runtime_error

Is there anything that I need to do before running this script?
BTW: /usr/local/share/usrp has a softlink to  /usr/pkg/share/usrp, but I don't 
beleive that this is the issue as other usrp scripts work fine.

I've a Rev. 2 USRP with 1 x Basic RX + TX
