About to polish an xplatform Desktop app to work on Linux too. Here a serial device is targeted that is built on a VCP driver module. macOS and Windows work mostly out of the box, where on Windows sometimes a Silicon Labs VCP driver must be installed by Innosetup.
Linux/Ubuntu is said to have a built-in VCP driver, and I checked it is so. Anyway, when I try to access the serial, I see dozens of serial ports but none that seems to be the real one. This test app is working with the device on Win and macOS, but it will not find a single usable port on Ubuntu.
Where do all this ports come from? Shouldn’t there only be connected ones like on the other platforms?
And any idea how to access the VCP device? There is also a Silicon Labs driver (as source code), but it will not compile with current Ubuntu Make.
EDIT: Found also this old case. Could be related.
