Re: Dell 7720 SE - Unknown device - might be a Bluetooth Driver problem

Hi lion7720,

I couldn’t understand all the images as the messages in the images were in a different language. Please reply with the Device Instance ID of the unknown device in “Device Manager”. To get the “Device Instance ID”:

1. Open the “Unknown Device” (the device with yellow exclamation).
2. Click the “Details” tab.
3. Select Device Instance Path or Device Instance Id (whichever is available for your version of Windows) from the drop down box.
4. Make a note of the Device Instance Path or Device Instance ID and add this in your reply.
