Looking at the source it is using libusb and searching for devices with VID ==  0x0483 and PID == 0x3748 or 0x374b. Usbconfig dump_device_desc will show you the details of your device.

If they do match I’m not sure where you would go from there without debugging the code but I think the permissions of your serial devices is a red herring.
