How to Check the VID and PID of a USB Device

As a software engineer working with USB communication, you often need to identify the Vendor ID (VID) and Product ID (PID) of a connected device. These unique identifiers are essential for debugging, driver development, or ensuring proper device recognition by your application.

So, how can you find the VID and PID of a USB device? The easiest way is through the Windows Device Manager. Follow these steps:

1. Open the Device Manager by right-clicking on the Start menu or pressing Win + X and selecting "Device Manager" from the list.

2. In the Device Manager window, expand the "Universal Serial Bus controllers" section.

3. Look for entries related to your device. These could be labeled as "USB Print Support," "USB Composite Device," or something similar, depending on the hardware.

4. Right-click on the relevant device and select "Properties" from the context menu.

5. In the Properties window, go to the "Details" tab.

6. From the dropdown menu, select "Hardware IDs" or "Device Instance Path." The VID and PID will be listed in the format "VEN_XXXX&PROD_XXXX," where "XXXX" represents the actual numeric codes.

This method works for most USB devices connected to your computer. If you're using a different operating system like macOS or Linux, the process may vary slightly, but the concept remains the same: identifying the device's unique identifiers for communication or troubleshooting purposes.
