lilliput um-80 no longer working after 1703 update

[AlbanRampon]

Bonjour,

We have read your post. I was away.
The PID 8060 means the device doesn't start, as you've already noticed.
I just looked at the schematics from Lilliput, this device uses a DisplayLink DL-195 chip.
That chip cannot be reprogrammed in the field, so the driver doesn't try to flash anything.
It looks like the log files were purged recently, as I don't see any history. This means I am unable to see what happened before the device started to appear as PID 8060.

The USB PID is presented part of the enumeration phase: when the device boots, it introduces itself to the computer so the computer knows which driver to choose.
Therefore the issue takes place on the device, before the driver is invoked.
This means trying different drivers won't affect the way the device behaves, it needs analysis on a bench.

I suggest contacting the manufacturer, Lilliput, to discuss a replacement.
Where are you based?

Kind regards,
Alban
