TS - Missing Drivers
There are no drivers that are specific to the BTM440. Like other Bluetooth earpieces, it is supported by the generic HFP drivers for your computer's Bluetooth adapter, which provide hands-free audio.
Unfortunately, these drivers can not be installed through Windows Update, and having Windows completely up-to-date will not ensure that the required drivers are present. Locating the correct drivers will depend on the type of adapter you are using:• If you are using an external USB Bluetooth adapter, the drivers should be available at the website of the company that manufactured the adapter.
• If your computer has built-in Bluetooth, the drivers should be available on the support page for the model that matches your computer.
