[solved, add user to right group] Lasercutter and Lightburn

I'm trying to get my devuan notebook to connect to may Lasercutter.
Software that came with the cutter is Lightburn and I can transfer files by using a thumb drive (copy the *.rd file onto it and the plug the drive into the cutter). But there is an interface to connect the cutter directly to USB (similar to a printer)
I have already installed pmount, so users are able to mount usb devices. The connection to the cutter is shown in the logs:

Sep 14 19:02:16 devuan kernel: [  526.280262] usb 3-1: new full-speed USB device number 3 using xhci_hcd
Sep 14 19:02:16 devuan kernel: [  526.481475] usb 3-1: New USB device found, idVendor=0403, idProduct=6001, bcdDevice= 6.00

Sep 14 19:02:17 devuan kernel: [  526.499684] usb 3-1: Detected FT232RL
Sep 14 19:02:17 devuan kernel: [  526.504635] usb 3-1: FTDI USB Serial Device converter now attached to ttyUSB0

So next step is installing "usbmodeswitch" to get usbserial?

Re: [solved, add user to right group] Lasercutter and Lightburn

No, according to the log there is a serial link set up (over USB) on /dev/ttyUSB0, so the next is to point the software to that.

First, of course, you need to make sure that the software (user) has permission to read and write /dev/ttyUSB0.
The "professional" way for that would be to make sure the user is in the special user group for operating that device, while the "hobbyist" approach is to simply chmod a+rw /dev/ttyUSB0 and let any user (on that computer) do anything to it.

OK, first apologies for not reading my logs properly (I usually do that and understand it, might wise to not do those things with a migraine head...).
If happen to come to germay (once you are allowed anyways), barbecue is on me.

And thanks, you where totally right. Group "dialout" it is, which confused me a bit first, till I remembered what the tty serial was firstly used for... *sound of the modem in my head*
