Hi,
I have just started to look into sigrok to try to use a Kings LA2106 under
Ubuntu 22.04.
The device gets recognised by the system and I extracted the firmware as
described in the Wiki. But sigrok-cli and pulseview do not seem to find the
device. Below are some details.
Any advice is appreciated,
Javier
