Hi

 I am using Fedora 6, on HP Pavilion 5000 laptop, with USB 2.0, a new
USRP
board (tested at Jan 2007) and GNUradio 3.0 installed without any
problem.

The board is seen as USB 2.0 device (when I used usbview).

Now, Whenever I try to run any example in the gunradio-examples
directory i
get the following error message


##############################################################################
[root@localhost usrp]# ./test_counting.py

usrp: failed to load fpga bitstream
/usr/share/usrp/rev4/std_2rxhb_2tx.rbf.

Traceback (most recent call last):

usrp_rx = usrp.source_s (0, rx_decim, 1, 0x32103210,
usrp.FPGA_MODE_COUNTING
)

return _usrp1.source_s(*args)

I suggest that you follow the BuildGuide on the wiki, and pay
particular attention to the part about setting up the udev rule.
Running as root is not generally recommended.

  http://gnuradio.org/trac/wiki/BuildGuide
  http://gnuradio.org/trac/wiki/FC5Install
  http://gnuradio.org/trac/wiki/UdevConfig


Also, why 3.0?  3.0.3 is the current stable release
