I see the same problematic behavior with the "lcd2usb" connections type for the hd44780 driver.
Here is the output: $ LCDd -f -r 5 -s 0 [ begin output ] Built on Mon, 01 Apr 2024 17:50:23 +1100, protocol version 0.3, API version 0.5 Using Configuration File: /etc/LCDd.conf Set report level to 5, output to stderr ...

[ end output ] I am guessing that optional connection types have not been selected for compilation into the library. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1789133 Title: LCDd does not support ConnectionType ftdi with driver hd44780 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lcdproc/+bug/1789133/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
