Hi

May I kindly request some information to help identify and address this issue?

In reference to your statement, "Every time I start the computer, the device cannot connect to Bluetooth devices," could you clarify the following scenarios:

1. The Bluetooth device does not automatically connect upon startup, but manual connection is successful.
2. None of the devices can be manually connected successfully.
3. A particular device fails to connect manually.

Additionally, did you select "Uninstall Device" in the device manager? Is the option "Attempt to remove the driver for this device" checked? Thank you in advance. 

Warm regards.

1- I try manually and it still doesn't connect.
2- Yes, it doesn't connect to any device manually.
3- The result is unsuccessful.
4- I tried uninstalling the device driver in both ways. Right now, it's enough to just uninstall the device from the device manager before shutting down the computer. The next time the computer starts, it connects directly to the headset automatically. But I do this uninstallation process before shutting down the computer.
