[Hackrf-dev] cannot talk to more than one hackrf one with Ubuntu 14.04

[Cinaed Simson]

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 cpld.
