How to Resolve COM Port Issues for Raspberry Pi Pico on Windows 11

Question

While trying to connect a Raspberry Pi Pico to a Windows 11 laptop, the board is not being recognized and does not show up at all. The COM port option in Device Manager is also not visible. Attempts have been made to fix this issue, including showing hidden devices and installing legacy ports, but nothing seems to work. Can anyone provide assistance?

Hello

Thank you for posting in Q&A forum.

Here are a few steps you can try:

1. Ensure you are using a data-capable USB cable, not just a charging cable. Some cables only provide power and do not support data transfer.
2. Hold down the BOOTSEL button on the Pico while plugging it into your laptop. This should make the Pico appear as a mass storage device named "RPI-RP2" in File Explorer.
3. Use the Zadig tool to install the correct drivers. Select "RP2 Boot" from the dropdown and install the WinUSB driver.
4. Ensure your Windows 11 is up to date. Sometimes, updates include necessary drivers or fixes for USB issues.
5. Plug the Pico into different USB ports on your laptop. Sometimes, certain ports may have issues or different configurations.
6. In Device Manager, find your USB Root Hub devices, right-click, select Properties, go to the Power Management tab, and uncheck "Allow the computer to turn off this device to save power."
7. Remove any other USB devices that might be causing conflicts, such as Bluetooth adapters.
