Can't connect serial port - Error: ch341-uart disconnected from ttyUSB0

I had a similar issue with a CH341. It was being picked up as a braille terminal. Do you get a message similar to
usb 1-1.2: usbfs: interface 0 claimed by skeleton while 'brltty' sets config #1
somewhere in the dmesg log? If so, renaming or moving the udev rules may help.

sudo mv /usr/lib/udev/rules.d/90-brltty-device.rules /usr/lib/udev/rules.d/90-brltty-device.rules.disabled
sudo mv /usr/lib/udev/rules.d/90-brltty-uinput.rules /usr/lib/udev/rules.d/90-brltty-uinput.rules.disabled
sudo udevadm control --reload-rules
