That's a distinct possibility (and a costly one).

Maybe you had a ground loop problem?

I admit I was doing weirdness on the poor boards. I was trying out running
USB over CAT 5 and had a USB transmitter and receiver setup with about 150
feet of CAT 5 between. The receiver, the unit near to the remote Hack was
powered from a 5 V linear regulator (LM117 with pot and caps etc). Had the
thing working pretty well with a bandwidth of 4 Mhz when disaster
occurred.
I found that the CAT 5 receiver was also blown so I did something way
wrong.
Some fun.

Just out of curiosity (and a desire not to step into something) do you
know how you killed the HackRFs? I've seen people who killed the input or
output RF amps because they weren't thinking about RF stages, and I've
seen a couple of reports of people killing them by using poorly regulated
battery based power supplies.

I managed to kill both my Hacks. Neither one will enumerate on the USB.
Tried several machines. No Luck.
Is there a service for repair of these machines?
