Could not connect RDV4 after 14a sniff

[jackman815]

Describe the bug A clear and concise description of what the bug is.

To Reproduce Steps to reproduce the behavior:

1. Start 14a sniff
2. Unplug the USB cable
3. put on reader
4. Press PM3 Button to stop.
5. Plug the USB cable and hw connect
6. [!!] ERROR: cannot communicate with the Proxmark3

Expected behavior Can not re-connect to PC after 14a sniff. I can connect again after restarting the RDV4 but lost all sniff data.

The pm3 isn't super simple to use. Complicated things like sniff in a scenario you describe is easy to make wrong. It doesn't mean the source code has a bug.

In this case I am pretty sure its a user related issue and I suggest you ask questions on discord or in the forum, which is the correct place to do it.
