Subject: Re: [Discuss-gnuradio] Error in my first USRP test
I found that I am using libusb-win32 version 0.1.12.0-1, I change it to
version 0.1.10.1-3. I plugged TX and RX in my USRP device. but I got this
error.
$ python test_counting.py
found 5 busses
found 5 busses
usrp_open_interface:usb_claim_interface: failed interface 2
could not claim interface 2, interface invalid
usrp_basic_rx: can't open rx interface

This is normal for Windows libusb0 0.1.10.1-3 the first time you try to
access the USRP. If you try it again (without removing power to the USRP)
it should work. See http://www.gnuradio.org/trac/wiki/WindowsTips for more
tips on using GNU Radio with Windows.
