I suspect the device was wiped as you stated. Is there a remedy to bring it
back to factory standards? There is a mictor connector with FX3 JTAG but
requires mating connector, programmer and binary image.
Thanks,

There is this:
https://www.ettus.com/all-products/jtag-fx3-cable-24/
There's a bootloader image here:
/usr/share/uhd/images/usrp_b200_bl.img
I don't know if that image can be programmed over JTAG, or some other
image is required. There is a utility:
/usr/lib/uhd/utils/b2xx_fx3_utils
That is used *when the device actually appears on USB*. In your case,
"side loading" through JTAG--->FX3 is not something I
have a procedure for, but, like I said, I'm trying to find out.

We tried plugging the unit into several PC’s and laptops, and it seems the

I'm trying to find that out. If it won't enumerate, there's no way to give the
FX3 a factory-fresh boot image over USB.
This has happened so rarely in the 15 years I've supported USRP devices that I
don't have a procedure committed to memory.
Is it possible that this device was "wiped" according to military security
standards for such devices?
