How Do I Find the VID/PID (Vendor ID/Product ID) for my USB-connected reader?
Answer:
Open the Windows Device Manager
Expand the Human Interface Devices node.
Double-click the device of interest -- the USB Human Interface Device Properties window appears.
Click the Details tab
In the Property drop-down box, select Hardware Ids
The USB HID VID and PID are displayed. My Cheeky USB Missile Launcher displays:
USB\VID_0ACD&PID_3810&REV_0001
The hexadecimal Vendor ID is highlighted in red, the Product ID in green, and the product revision number in blue.
