Hey everyone, I’m trying to use the Arducam Serial Number Tool on two B0332/OV9281 cameras and I keep getting an error: “Unknown Device! Please contact [email protected]”. I downloaded the tool from the guide at Redirecting.... Both cameras throw the same error every single time I run it. Has anyone run into this before?
Thanks for the details. Just to confirm a couple things: do both cameras show up normally in your OS before you run the tool? And are you running it with one camera connected at a time or both connected at once? Also, what OS are you on?
Both cameras show up fine in the OS. I’m on Windows, and I’ve tried it with one connected at a time and also with both connected. Every attempt returns the exact same message: “Unknown Device! Please contact [email protected]”. I repeated it many times and there’s no other error or code shown, just that popup.
Got it. That error usually means the version of the Serial Number Tool you have doesn’t recognize the B0332/OV9281 hardware, so it falls back to the Unknown Device message instead of reading the device. I have an updated version of the tool that handles these cameras. I’ve sent you the download through private message — please check your messages and try it with just one camera connected first.
I tried the updated tool you sent and it worked great, thank you! It recognized both cameras without the Unknown Device error.
Glad that sorted it. To sum up for anyone else hitting this: the older Serial Number Tool from the guide didn’t identify the B0332/OV9281 devices and returned “Unknown Device! Please contact [email protected]”. The updated tool (sent via private message) recognizes them correctly. So if you see the same error with B0332/OV9281, the fix is to use the updated Serial Number Tool from support rather than the one currently in the guide.
