Lightburn doesn’t recognize the fiber laser plugged into USB. This is an existing installation that I’ve used with our Ruida CO2 laser. I’m just adding the fiber laser device. The operating system sees the device - lsusb output : Bus 001 Device 002: ID 9588:9899 BJJCZ USBLMCV4. And lightburn lists a USB device port #7, however, lightburn only reports “waiting for connection” I added the device manually because a search for the device didn’t work. Thank you Joe ---

What Linux distro and version? It’s just treated as a libusb device and _should_ just work. Might be worth trying to run LB as root and re-running the device discovery. If that works then you likely need to tweak udev rules or something. But on Ubuntu and Fedora, the distros we support, it has generally just worked without anything special. Please also goto Help \> Generate Support Data Then paste that output here. ---

I’m using Zorin - an ubuntu derived distro. I ran Lightburn as root, and it did find the laser. Here is the requested support data: [Support Data Redacted] ---

Check the permissions on the usb device and see if they match up with your user or groups that your user is in. Might need to add a group to your user or change some udev rules. Zorin probably has some slightly diff setup for USB and it’s not sticking it in the right group for you to be able to access. ---

thank you. Udev is of course, convoluted. I’ll let you know how I get it fixed. Thank you for your guidance. ---

Ok, I should have a solution for you: Run `sudo gedit /etc/udev/rules.d/usb.rules` (you can also use nano, vi, whatever) Enter the following contents ```auto SUBSYSTEM=="usb", MODE="0666" ``` Save the file and close. Then run: `udevadm control --reload-rules` Now plug your galvo USB connection back into the machine. Run LightBurn without sudo and you should be able to automatically find and connect to the device. ---

Sadly, that didn’t work. There are a large amount of rules written in ‘70-snap.snapd.rules’ - that is written over each time the system is patched. I also tried adding ‘36-snap.snapd.rules’ with the SUBSYSTEM rule, but still no luck. I opened a ticket with Zorin and await their response. Thank you for your help, I don’t think it’s a huge problem, just a frustrating delay. Joe ---

Ok, thanks for the update. Stuff like this is, unfortunately, one of the reasons why we say we support Ubuntu and Fedora specifically, but none of their variants or derived distros. Mint, for example, has been terrible to work with. So much changed under the hood. We tested the solution I gave on Ubuntu 20 and 22 ---

Belay my last! I changed the USB port it was plugged into and it found the laser! Yay! Thank you for your speedy reply and solution! Joe ---

Excellent! Weird that you had to change ports but glad it works! ---

actually, I think I could have unplugged and plugged back into the same port and it would have found it as well. I just needed to refresh the udev rule engine with a device connection. ---

Could have possibly forgot to bounce the udev subsystem after the change or for some reason it didn’t restart the subsystem but unplug/replug did. ---

Either way, I’m happy. Thanks again! ---
