I suspected this could be the problem as I didnot use pybombs in the first 
place, I will try this one, 
Thanks.

                   Use pybombs ( http://pybombs.info/ ) to install the latest 
gnuradio,     gr-osmosdr and everything that it needs. The packages in most 
Linux     distributions are not the latest and greatest normally, there are     
exceptions like pentoo.

cannot talk to more than one hackrf one withUbuntu 14.04 See if you can upgrade 
gr-osmosdr:    apt-get install gr-osmosdr When you start grc, it should print 
out the serial numbers of all the HackRF devices it finds - and indicate if 
it's a match or it's skipping it based on the serial number you provided. Note, 
I'm assuming you upgraded libhackrf when you upgraded the firmware and the

ubuntu 14.04, with three HackRF one devices connected to the system. All three

individually. HackRF_info can identify all three devices (see below), however 
when I run osmocom_fft with -a hackrf=0/1/2 options, the same HackRF device is 
always selected for streaming instead of the specified ones by -a               
    hackrf=options (I                     can see the RX led lit from the same

anyone give a clue?                   Accroding to the gr-osmosdr wiki page, 
one can use the serial number instead of the device index:

better. Alex _______________________________________________ HackRF-dev mailing
