What is device name?

[WebKenth]

        $reader = \USBScaleReader\Reader::fromDevice(deviceName: '/dev/scale');

Could use a few pointers to find out what /dev/scale is supposed to be

Can't open scale device isn't exactly telling what's wrong

You're right. There are a lot of gaps, so nowadays I prefer to roll with this app. It really makes the headaches go away, plug and play.
