We have a couple of B205mini boards left over from a previous job, trying to re-purpose. Both acting the same:

1) Plug into USB and get amber power light.

2) uhd_find_devices reports “No Devices Found”.

3) “sudo lsusb” does not report anything looking like the B205mini.

4) /usr/lib/uhd/utils/b2xx_fx3_utils reports “cannot open device”

Is there some initial firmware on the device that is possibly corrupted? Do I need to program the device via JTAG? Is there a special programming cable for this purpose?

If plugged in to a USB 2.0 port, you may need a "Y" cable to extract power from *2* USB ports.
