>> Having remote access to the scanner isn't enough. When testing, you
have to ear and see how the scanner is behaving. And you often turn it off
and on to reset it to a clean state.
> If the scanner can be switched off remotely to reset it, or to avoid
stressing it when backend doesn't behave correctly, I'll have a try working

The live-stream is located at:
The green power strip is attached to the scanner and a room lamp, both
controlled by 'sudo /home/dev/usbpower [on|off|status]' via a
USB Net Power 8800 relay. The camera and computer are attached to an
always-on power strip.
The relay, scanner, and a ThinkPenguin TPE-N150USB WiFi adapter are
connected via a 5-port PCIe USB card; no devices are attached directly to
the host USB. The TPE-N150USB has issues with warm-resets  ; the host
ports are always-on and hopefully the PCIe card is more robust to do
development work. Reboots should be safe and streaming will resume

The ThinkPenguin TPE-N150USB adapter uses libre firmware, located at ,
with a replacement kernel module from Ubuntu. The adapter is hopefully
stable; this is something of a stress-test.
