[Hackrf-dev] And I can't make work 2 hackrf boards in GRC

[Leandro Leoncini]

  Hi, I can't make work 2 hackrf at the same time in GRC. Both devices work
well one at the time but not at the same time. When both are connected I
can see them in hackrf_info:

hackrf_info
Found HackRF board 0:
USB descriptor string: 0000000000000000321864c83940521d

Serial Number: 0x00000000 0x00000000 0x321864c8 0x3940521d

Found HackRF board 1:
USB descriptor string: 000000000000000014d463dc2f8e9ce1

Serial Number: 0x00000000 0x00000000 0x14d463dc 0x2f8e9ce1


  But when I start using one of them in GRC this is what I get:

hackrf_info
Found HackRF board 0:
USB descriptor string: 0000000000000000321864c83940521d
hackrf_open() failed: HACKRF_ERROR_LIBUSB (-1000)

This is my dmesg

  I'm on Linux Mint 17.3 with GRC 3.7.9.1 so any idea of what can be the
problem?

Thanks!
