[cura 2.1.2 cant find printer]

A cleaner way to reintroduce other printers is to modify the getSerialPortList function in USBPrinterOutputDeviceManager.py.

Around line 263:

-                    if not only_list_usb or "USBSER" in values[0]:

+                    if not only_list_usb or "USBSER" or "VCP" in values[0]:

This simply lets Cura accept both USBSER and VCP as valid port types.

For Anycubic Prusa i3 Printer I used :

+ if not only_list_usb or "USBSER" or "VCP" or "SILABSER" in values[0]:

It worked nice on Win 10 even for USB printing.

Thank you for your help.
