[Bug 1990357] Re: ch340 USB/serial - brltty interference

[Matěj Pavel]

** Description changed:

  the CH340 does show up in lsusb:
  'Bus 001 Device 005: ID 1a86:7523 QinHeng Electronics CH340 serial converter'
  
  but does not show up in /dev if brltty is installed on the system.
  
  Device does show up as /dev/ttyUSB0 after removing brltty and rebooting.
  
  tested systems:
  Ubuntu 22.04.1 (live USB) - problem present
  Linux Mint 21 (fresh install, updated) - problem present
  
  ubuntu-bug does not recognise brltty as an ubuntu package and thus
  refuses to collect data.
  
- The ch340 is a very common chip used in cheap 3D printers and
- microcontroller development boards.
+ The CH340 is a very common USB-serial converter chip used in cheap 3D
+ printers and microcontroller development boards.
