Connect Bluetooth gamepad to Android box that doesn't have Bluetooth

[Eldin]

I have Android TV Box and I want to play games on it via Steam Link app.
For that I need gamepad.

I have Bluetooth gamepad but Android box doesn't have Bluetooth built in.

I have Bluetooth USB Adapter.
When I plug that adapter to my PC, I can enable Bluetooth in PC settings and connect gamepad or any other Bluetooth device to my PC.

But when I plug in that Bluetooth adapter to Android TV Box, nothing happens.
There's no any Bluetooth settings in Android TV Box.

Does anyone know any other way to make Bluetooth USB Adapter work with Android TV Box so I can connect gamepad to it?

TV Box is rooted so I can mess around with system files if necessary.

I assumed this one would have Bluetooth too.
I was surprised when I saw that it has no Bluetooth at all.

And I paid $35 for this box.
There's no much difference in price between box you linked and box I bought, but difference in specs is big.
The one you linked has 1GB DDR RAM, 16GB storage, Mali-450MP6 GPU, runs on Android 4.4 and has 32-bit CPU.
And the one I bought has 4GB DDR3 RAM, 32GB storage, Mali-T720 GPU runs on Android 9.0 and has 64-bit CPU.

But I'm obviously asking at the wrong place.

Nope, right place because you already got the correct answer. All hardware needs drivers to interface with the OS. Windows has a ton of them built-in, through various means. Android doesn't. You either get the drivers (*), or you bought an expensive paperweight, learned why it was discounted and why you buy android boxes, chrome books and other specialized stuff with the specs you need, rather than assuming upgrading is possible or as easy as windows.

* The manufacturer or places like github and similar open source developers which may offer generic bluetooth drivers that will get your adapter to function. Good luck on your search.

I tried searching a little bit and couldn't find anything useful.
Android comes with some Bluetooth driver. I've seen videos with people that have some Chinese phones without Bluetooth. They connected Bluetooth USB adapter via USB OTG and it worked.
I don't know why it doesn't work on my Android box.
I'll install Android on my PC tomorrow, connect USB Bluetooth Adapter to it and try it out just to see will it work.

If I don't figure out anything then I'll probably just purchase gamepad that comes with wireless dongle. That'll work.
