Are you writing this from scratch rather than using GNU Radio? Using
libHackRF to communicate with the hardware?

I know that someone was implementing a gnu radio flow graph with both
TX and RX (using two HackRF One units) and came across problems with
USB contexts. I wonder if this is related to the same problem.

I can successfully reproduce this problem with the following script:
#!/bin/bash
i=0
j=0
while [ $i -eq 0 ]
do
hackrf_info > /dev/null
i=$?
j=$[$j+1]
done
echo "Failed on attempt $j"

Are you using the 2014.08 release or the latest code from GitHub?
Have you tried switching between TX and RX without closing the device?
Thanks,
Dominic
