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.
