We need an ActiveX object (COM) to read out a USB port and represent the data from the USB device (Scale) on a webpage.
It is possible to do a createobject in javascript in Internet explorer.
The Scale can give readings in KG or LB. See the different readings of the USB Trace
idVendor: 0922 Dymo-Costar Corp.

This is the 4th byte (44) we need to have and represents the weight
^ This is 3th byte (03) : the value that indicates the value of byte 4 is in KG
