On mobile editions of Windows, such as Windows 10 Mobile, only drivers that are part of the operating system are loaded. Microsoft encourages you to use in-box drivers whenever possible. For information about INF sections, see Overview of INF Files.

For examples, look through the INF files included with sample drivers and find devices similar to your device.

If your device specifies class and subclass codes to 02, and you want to load another driver instead of Usbser.sys, you have to write an INF that specifies the hardware ID of the device and the driver to install.

In this case, you might have to load your own driver or write an INF that references another in-box driver. If a suitable driver is not found, the device might not have a driver loaded.

The Plug and Play manager tries to find a driver.

If your device specifies class code 02 but a subclass code value other than 02, Usbser.sys does not load automatically.

With this approach, you are not required to distribute INF files for your device because the system uses Usbser.inf. For more information, see USB communications device class.

If you want to load Usbser.sys automatically, set the class code to 02 and subclass code to 02 in the Device Descriptor.

The driver is loaded based on a compatible ID match similar to other USB device class drivers included in Windows. You do not need to write your own INF to reference the driver. If your device belongs to the communications and CDC control device class, Usbser.sys is loaded automatically. Starting in Windows 10, Usbser.inf was added to the %Systemroot%\INF directory, which loads Usbser.sys as the functional device object (FDO) in the device stack. For the list of USB device class driver included in Windows, see USB device class drivers included in Windows. If they are not installed automatically, contact the device manufacturer.

I just did this a few minutes ago so I don't know whether Windows 10 will undo the modifications one day. Hit OK a bunch of times and you're all set. You have to type in 'NT Service\TrustedInstaller' (this won't show up in search results, so just type/copy+paste it w/o the ''s). Edit the permissions again and remove the 'Everyone' permission you created. In Device Manager, it shows up under the Bluetooth sub-tree as 'Microsoft Bluetooth Enumerator', 'Microsoft Bluetooth LE Enumerator', and 'My new generic Bluetooth adapter'.Īfterwards, I recommend putting all the bth.inf permissions back to the way they were.

Hit 'Edit' and add 'Everyone' - Full Control. Then pull up the properties on it again, go back to the 'Security' tab. a few times to get out of the properties dialog. Here's a workaround.īrowse to the file, right click, click Properties. The first time I ran it, it failed because it couldn't write to C:\Windows\inf\bth.inf. Assuming this app is safe (I crossed my fingers), it does create a restore point before it starts installing, so if it screws anything up, you should be able to roll back. I just ran 1.0.1.98 Beta 64-bit on Windows 10 Professional 10240 (presumably RTM). there's a freeware app called Bluetooth Driver Installer.
