Unable to read from a USB HID Scale.

YeetSir commented 3 years ago

I'm attempting to read a scale via USB with Device.net. I'm able to connect to the scale but I'm unable to read from it. When my code gets to this line: await usbDevice.InitializeAsync().ConfigureAwait(false); i get "Could not open connection for reading" coming from WindowsHidHandler.cs Line 107. Can you all please help? :)

The Windows sample seems to be picking up the device here:

(Usb - a5dcbf10-6530-11d2-901f-00c04fb951ed) Device Path: \?\usb#vid_1c19&pid_0002#6&2af6c4ed&0&3#{a5dcbf10-6530-11d2-901f-00c04fb951ed} Vendor: 7193 Product Id: 2

Try connecting with the path "\?\usb#vid_1c19&pid_0002#6&2af6c4ed&0&3#{a5dcbf10-6530-11d2-901f-00c04fb951ed}"

Like this:

        public async Task TestConnectToSTMDFUMode_GUID_DEVINTERFACE_USB_DEVICE()
        {
            const string deviceID = @"\?\usb#vid_1c19&pid_0002#6&2af6c4ed&0&3#{a5dcbf10-6530-11d2-901f-00c04fb951ed}";
            var windowsUsbDevice = new UsbDevice(deviceID, new WindowsUsbInterfaceManager(deviceID));
            await windowsUsbDevice.InitializeAsync();
        }

Darn, unfortunately, I'm getting this error: "Device handle no good. Error code: 123"

Here is the output log:

Do you have any other suggestions that I may be able to try? Thank you, good sir!

MelbourneDeveloper commented 3 years ago

Starting to clutch at straws here. It might be the permissions when trying to connect.

But, I also think this might be a serial port device. Try running the windows sample and see which com ports show up. When you remove the device, does the com port also disappear?

Lastly, does the manufacturer have a sample app in some language?

YeetSir commented 3 years ago

Good Morning! The device that we are attempting to communicate with uses a USB cable. It's Rice Lake Postal Scale Model BP 1214-75S. We can connect, and use this device when we make a .Net Framework project with another USB driver. However, this .net core project using device.net, we cannot communicate with this USB scale. It's it a problem that we are using .net core to talk to a USB device? Here is the manufacturer's product page for this device: https://www.ricelake.com/en-US/products/product-details/benchpro-series-shipping-postal-digital-scale#/information

I've reached out the Rice Lake for some sample .net core code and I'm waiting for their response.

Thank you for all your help here! I can't wait to get this rocking and rolling! :)

Ask them if it uses :

Serial port Usb Hid

Follow my instructions on checking the com port
