Ubuntu 22.04 port already in use

[cptkirk (David Kirk)]

Ok. First I couldn’t get LightBurn to connect to the ORTUR. I found the forum post No connection to Lightburn after upgrading to Ubuntu 22.04
and that helped me get it connected except I don’t return anything for grep -riIn “303a:4003” /usr/lib/udev/rules.d/*
I did add a line in 70-usb-uaccess.rules.
however Now it says the device is already in use and I am coming up empty o where it thinks it is in use.
I have the usb ports open and lsusb shows:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 0cf3:e007 Qualcomm Atheros Communications
Bus 001 Device 002: ID 303a:4003 Ortur Laser Master
Bus 001 Device 004: ID 0a5c:5832 Broadcom Corp. 5880
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The printer is directly connected to my Dell Laptop. Any thoughts?

try “ps -fe | grep brltty”

if it returns something which looks like the brltty process is running then you need to remove the brltty process from the system: sudo apt-get purge --auto-remove brltty
should do it.
