I have a Hackrf in mint condition - for various reasons with busy schedule I 
could not use it.

I would like to sell it now - if any body interested - please let me know.

I'm using 2 HackRF's and the udev rules are installed.

The problem arises when you have 2 HackRF's plugged in, and one is being
use and the other one isn't.

If hackrf_info encounters the device being used first, it exits with an
error and it doesn't query the other device.

If hackrf_info encounters the device not being used first, it prints out
the info for the device, moves on to the second device and then
generates the normal busy error.

The serial numbers are different and they are not zero - although
there's a large zero prefix.

The "Device Arguments" field in gnuradio is the last 8 characters of the
serial number displayed by hackrf_info, e.g.,

  hackrf=c894567e

where

  c894567e

was extracted from the serial number

  Serial number: 0000000000000000406464c8c894567

If you can't get them both to work at the same time, then you need to
post the output of

  hackrf_info

while both HackRF's are not being used.
