Title:
  BRLTTY grabs my FTDI USB serial port adapter & Arduinos!

Status in brltty package in Ubuntu:
  New

Bug description:
  Clean Ubuntu 22.04 LTS install.
  brltty grabs several of my FTDI USB serial port adapters and all six of my Arduinos. It appears this happens because there is a new udev rule that wasn't in Ubuntu 21.10:

  $ lsusb
  Bus 002 Device 013: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC

  $ grep -i ftdi /lib/udev/rules.d/*
  85-brltty.rules:# HandyTech [FTDI chip]
  85-brltty.rules:ENV{PRODUCT}=="403/6001/*", ATTRS{manufacturer}=="FTDI", ENV{BRLTTY_BRAILLE_DRIVER}="hd,hm,ht", GOTO="brltty_usb_run"

  Appears to be the same bug as the following (i.e. brltty is grabbing a LOT of USB serial chips):
  Bug #1970408
  Bug #1958224

  It appears there are two fixes:
  1. Comment out the offending udev rule.
  2. Uninstall brltty. That's what I did.
