[Hackrf-dev] Where is a problem

It looks like the gr-osmosdr block is expecting you to have a USRP attached
and failing to find it.

If you double click on the gr-osmosdr block, there is a field called
"Device Arguments". Try setting that field to "hackrf=0"

I have just started recently with GNU Radio and HackRF.
I tried the first lesson at
http://greatscottgadgets.com/sdr/1/
But it does not work for me.
See the output below.
Can anyone help?
Thank you
