[Bug 1972030] [NEW] BRLTTY grabs my FTDI USB serial port adapter & Arduinos!

[David Spoelstra]

Public bug reported:

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.
