Ping1D not working after being powered off

Hi everyone,
I started working on a BlueROV2, which had a Ping1D mounted on. After some bit of success to connect to it, but not at all consistent, I tried to open it up and found that their was quite some humidity in it. There was not a lot of corrosion so I cleaned it and could flash the firmware successfully.
But now, I can see the scanning on ping-viewer, but only if I keep the power on, just after flashing the sensor. If I disconnect it and reconnect the USB cable, impossible to connect again, and I have to re-flash it.
Could the memory be corrupted when powered off ? I really don’t understand what is happening with this sensor…
