      Due to component conflicts, the ch340 serial device cannot be used normally on ubuntu22 systems.

        305.764435] usb 1-1.3: new full-speed USB device number 7 using ehci-platform
      [  305.979075] usb 1-1.3: New USB device found, idVendor=1a86, idProduct=7523, bcdDevice= 2.64

      [  305.979693] ch341 1-1.3:1.0: ch341-uart converter detected
      [  305.980778] usb 1-1.3: ch341-uart converter now attached to ttyUSB0
      [  306.554038] input: BRLTTY 6.4 Linux Screen Driver Keyboard as /devices/virtual/input/input8
      [  306.557920] usb 1-1.3: usbfs: interface 0 claimed by ch341 while 'brltty' sets config #1

      user need to do:

      sudo apt remove brltty
      

      plugout uart module and plugin again.
