C# - How to Read data coming in via a USB Port

Question

Hello. I have a MS Visual C# (2013) WPF program that I'm trying to read data being received on a USB port. I have code that will recognize the USB Device (A ADB-S Usb Dongle) as
VID: 0BDA
PID: 2838
Friendly Name: RTL2838UHIDIR
Device Class: UsbDevice
Device Location: Port_#0002.Hub_#0002
Device Path: PCIROOT(0)#PCI(0B01)#USBROOT(0)#USB(2)
Device Physical Object Name: \Device\USBPDO-3

My question is, How do I read data that is streaming in from this device?

The existing library has no code to allow reading of the incoming data.
Can someone please provide C# source code that will read data being received?

Thank you.
Brad H.

Have a look at Working with USB devices in .NET[^]

This cannot be answered because we do not know what the device is. Is it implementing an RS232 device (probably not) or are you talking about accessing a USB interface directly. If so you will need to find and provide heaps more information and there is no generic solution. It may implement the HID interface (from its name) and that could make life a little easier.
