Troubleshooting
USB scale not detected by HID-ScaleWedge
If HID-ScaleWedge doesn’t list your USB scale, check whether the scale uses the USB-HID protocol or shows up as a virtual RS232 COM port instead.
Scenario: Your USB-connected scale does not appear in the HID-ScaleWedge device list.
Before collecting data from your scale, ensure that it is a parcel scale that implements the HID Scale USB interface protocol (also called USB-HID). Many scales that directly connect to a USB port do not use the HID Scale USB protocol, instead using a Virtual RS232 COM port protocol which does not communicate with HID-ScaleWedge and requires driver software to be installed. This will cause the scale to appear as a COM port in the “Ports (COM & LPT)” section of the Windows Device Manager (see Identify your device’s COM port with Device Manager for more details).
If this is the case, then our BC-Wedge or WinWedge software would be more suitable for collecting data from this scale. Contact sales@taltech.com for more information and, if you have already purchased HID-ScaleWedge, provide your order information to receive assistance switching.
