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.
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.
