 The device link is not complete until you

The device link is not complete until you have software reading the data. Here is a minimal C++ example using WinUSB API to read pen coordinates:

#include <windows.h>
#include <winusb.h>
#include <setupapi.h>

// Use the same GUID from the INF
// 337FD5C2-7F7D-4F8E-B7F7-8F8B8E8D8F8A
DEFINE_GUID(GUID_DEVINTERFACE_MyTablet, 0x337fd5c2, 0x7f7d, 0x4f8e, 0xb7, 0xf7, 0x8f, 0x8b, 0x8e, 0x8d, 0x8f, 0x8a);


int main() 
// 1. Find the device using SetupDi API
// 2. Create a WinUSB handle via CreateFile
// 3. Read from the interrupt pipe (pen data)


HANDLE hDevice = CreateFile(devicePath, ...);
WINUSB_INTERFACE_HANDLE hWinUsb;
WinUsb_Initialize(hDevice, &hWinUsb);
UCHAR penPacket[8];
DWORD bytesTransferred;
while (true) 
    WinUsb_ReadPipe(hWinUsb, 0x81, penPacket, 8, &bytesTransferred, NULL);
    // Parse X, Y, pressure from packet
    // Send to GUI or game engine

Most commercial tablets (Wacom, Huion, XP-Pen) use proprietary, monolithic drivers. However, if you are building a custom open-source tablet or repurposing an old device, the standard driver package will not work. This is where WinUSB becomes your best friend.

Symptom: Yellow bang in Device Manager.

Solution:

If you have ever plugged a graphics tablet (like a Huion, XP-Pen, or a custom DIY pad) into a Windows PC and dug into the Device Manager, you might have stumbled upon terms like "WinUSB" or "Device Link" . These aren't random errors—they are critical components of how your tablet communicates with your creative software.

This article breaks down the chain: Graphics Tablet → USB Device → WinUSB Driver Package → Windows Link.
