Review on 🔌 ASUS USB-BT400 USB Bluetooth Dongle Receiver - Compatible with Laptops and PCs, Plug and Play for Windows 10/8/7/XP. Supports Printers, Phones, Headsets, Speakers, Keyboards, and Controllers in Black. by Stanislaw Kosciukiew ᠌

I bought it because of the presence of support for Windows XP in the specification. To support Windows XP, the kit comes with drivers that are successfully installed. But the device itself cannot be made to work, with all operations a "license check" error pops up. A fairly long communication with ASUS support did not lead to anything, different ways of dancing with a tambourine were tried, but none of them was particularly meaningful. As a result, the adapter was handed over to the seller, who promises to somehow return the money for it.
