bladeRF x40 appears dead

I'm on Ubuntu 18.04 and have several bladeRF devices. They always at least show up in dmesg. Now I get absolutely nothing.

Power LED is on at least. But that's all. Ideas?

And this is a sudden problem with all of your bladeRFs? This sounds very strange. Can you try another machine, or perhaps use the GNU Radio Live image? Do the devices show up in lsusb? Can bladeRF-cli -p detect them?

Take a look at the schematic and probe all the voltage rails when it's plugged in. Please report any anomalous readings.
