xTools F1 Communication Issue

[mbejerano (Marc Bejerano)]

I’m having issues connecting to my XTool F1.

• I am running Ubuntu 24.04 and have the CH341 driver installed and running.
• The user is a member of group tty
• The user is a member of group disk
• Package brltty has been uninstalled
• The CH341 says that it has renamed the usb0 to cdc_ether (not sure if that’s helpful)

The Lightburn software cannot find the tool.

Is there some setting or other that I have missed somewhere?

@mbejerano

• The user is a member of group tty
• The user is a member of group disk

Have you confirmed that you’re in the dialout group?

Run groups command and return output please.

@mbejerano

• The CH341 says that it has renamed the usb0 to cdc_ether (not sure if that’s helpful)

Can you locate the device file in the filesystem and show the directory contents? Please capture and post the output.

Do you see any ports listed at all in LightBurn in pulldown? Can you take a screenshot?

Most of these end up being in the /dev directory… if it made it, might try

ls -l /dev/cdc*

I can identify my fiber on the usb hub with lsusb, but I can’t ever find a /dev entry for it. I powered it off, which is the disconnect in the entry below. Then powered it back on. I get one line in dmesg and there is no entry that I can find or that I know of in the /dev directory.

jack@Kilo:~$ sudo dmesg | tail

Maybe different enough, it doesn’t matter…

Good luck
