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 Gluszek ᠌

The adapter finds devices but does not add them to the list of audio devices. I go to Bluetooth Device Control Connect to the Bluetooth (SRS-XB21) stereo headphones. I click Connect. After a pause, an error is thrown: Error connecting to headset. Please retry this operation. Tried with JBL T450BT headphones and Sony SRS-XB21 speaker. I installed the driver from the disk (version 6513700) and the driver from the site (version 6516000). The result remains the same. All actions were performed on an ASUS N550JV laptop.
