importing files takes really long without indication of it doing anything

[DowneyX]

Cura Version

5.7

Operating System

arch linux

Printer

ender 3 v2 neo

Reproduction steps

1: open cura.
2: click on folder icon
3: select stl

Actual results

there is no prompt telling me that it is working on importing my model. it takes a full 3 minutes to load a simple STL file.

Expected results

it should prompt me that it is importing my file.
it should also take less than 5 seconds to import a simple STL file

Add your .zip and screenshots here ⬇️

looking at the logs it seems that the issue stems from the USBPrinting.AutoDetectBaudJob job. it is trying to establish serial connections with all my tty ports (and failing). after this process is done it imports my STL file.

a work around for now is to disable the USB printing plugin

Oh wow, that is a lot of usb ports that it's trying to poll.

If you don't want usb printing, the workaround is indeed to disable the usbprinting plugin

I was also confused, but here's how to disable: Open Cura, click "Marketplace" top right; in new window click gear icon top right; scroll down a lot (about 1/3 of the scroll bar) and disable "USB Printing". It is (I think) a default extension.

This works for me, thanks!
