I installed Armbian 23.11 Bookworm Kernel 6.1, Size: 482Mb, Release date: Nov 30, 2023. After installation, a CH340 based board was connected to my original Tinkerboard and recognized. Subsequently, I used armbian-config to provide the default desktop (Cinnamon flavor). Thereafter, the CH340 board is incompletely recognized. Specifically, no device is presented as /dev/ttyUSB?. The device appears in the list
Very weird, if the kernel module is loaded, there should be the device under /dev too.
From dmesg I see something suspicious:
[ 1249.869135] usbcore: registered new interface driver ch341
