drivers for waveshare RS 485 usb serial converter for huangyang vfd

I/my goto linux guy installed the debian 12 live cd last weekend. We could not get the spindle going, apparently because of drivers for the old rs 486 usb to serial converter.I bought one made by waveshare which aparantly should work. However, it wants to install some drivers but cannot find them.Is there a way I can get them working without the help of my linuxcnc guy?

This is the converter: www.waveshare.com/wiki/USB_TO_RS485  

 

In a terminal
lsusb
before and after inserting the waveshare, post results here.

is should not require any additional driver. just dismiss that stupid popup...
check dmesg after plugging it in. /dev/ttyUSB0 or /dev/ttyACM0 should appear - that's the device to use

That raises a lot of questions, mostly not related, but:
Do not install any of those, none.
-brltty is for keyboards with braille for visually challenged people
-cgminer and pcgminer are miners, as in crypto miners for several algos
-no idea what the rest is, but i am sure you do not need those, for now
Your adapter is FTDI for programing STM and stuff, no idea if it works as RS485

Britty and speech-dispatcher was installed by default on Debian 12.2 or similar. One of my associates complained about it until he ended up removing it with apt.
The Linuxcnc ISO should not install it as I (hopefully) supressed their installation
Ref:  github.com/LinuxCNC/linuxcnc-live-build/...sts/desktop.list#L18
In a therminal window, Try typing
sudo apt remove britty speech-dispatcher

i've found the exact same waveshare dongle. and it behaves as expected in debian12, without suggesting any weird software install
