How can I find the VID and PID of a device on the other end of a USB-to-Serial adapter?
You can find the VID and PID of a device connected through a USB-to-Serial adapter in Windows by following these steps:
Connect the USB-to-Serial adapter to your computer and plug in the device you want to identify.
Open the Device Manager by pressing the Windows key + X and selecting "Device Manager" from the menu.
Look for the entry under "Ports (COM & LPT)" that corresponds to your USB-to-Serial adapter. Expand the entry by clicking on the arrow to the left of it.
Right-click on the entry for your device and select "Properties" from the menu.
Click on the "Details" tab.
In the "Property" drop-down menu, select "Hardware Ids."
The VID and PID are listed in the "Value" field, separated by an underscore. The VID is the four-digit number before the underscore, and the PID is the four-digit number after the underscore.
Alternatively, you can use third-party tools such as USBDeview to easily identify the VID and PID of devices connected to your computer.
