Why no focus at any distance on USB 2 boroscope

Grainy and unfocusable even afte messing with the camera settings

Thanks for getting in touch! Can you show me a picture of the device you’re using? We don’t sell a borescope and I want to be sure I’m giving instructions for the correct product.

We haven’t heard back from you, so I’m hoping you were able to resolve the issue. If that isn’t the case, please contact us at support@plugable.com for assistance!
