dmesg [ 1431.007315] usbcore: registered new interface driver usbserial [ 1431.007323] usbcore: registered new interface driver usbserial_generic [ 1431.007330] usbserial: USB Serial support registered for generic [ 1431.008619] usbcore: registered new interface driver ch341 [ 1431.008629] usbserial: USB Serial support registered for ch341-uart
- its very nice that Serial support is registered, but not attached for example: to the BUS 003 Device 001: ID 1A86:.... (and this is important) ls /dev/tty* /dev/tty /dev/ttyS22 /dev/tty0 /dev/tty24 /dev/tty4 /dev/tty55 /dev/ttyprintk /dev/ttyS23 /dev/tty1 /dev/tty25 /dev/tty40 /dev/tty56 /dev/ttyS0 /dev/ttyS24 /dev/tty10 /dev/tty26 /dev/tty41 /dev/tty57 /dev/ttyS1 /dev/ttyS25 /dev/tty11 /dev/tty27 /dev/tty42 /dev/tty58 .....and so on. but nothing with ttyUSB0, ttyUSB1, or ttyACM0, ttyACM1.
