Dear fcM127qP, Greetings, this is ASRock TSD. There are some suggestions for verifying: 1. Please refer to the user manual to clear CMOS. (page 28) 2. Please re-install the Bluetooth driver. 3. Please install the device to different USB ports to verify. 4. If possible, please change another Bluetooth device for verifying. Thanks! All the best, ASRock TSD |

i doubt clearing cmos will help, i use intel BT too (its on that small m.2 wifi card) 1) bluetooth has low bandwidth to begin with 2) its using 2.4GHz which can interfere with wifi if u live in crowded area with bunch of wifi hotspot around which will degrade it by alot 3)if u have enabled 2.4GHz wifi, your antena wont keep up, and having bigger antena wont really help you, because intel didnt design in to be used with high gain antennas (intel manuals) i have 2.4GHz disabled, BT mouse is working fine, BT speaker are working fine (in pcm stereo/dts/dolby), but i cant use BT microphone (built in on headset), once i use it as default microphone, my mice gets in slowpoke mode i also did try doing same on my android phone, same result :)

sources apple/intel anyway, if u really must have both mice and headset working properly (cheapest way possible): connect your BT mouse with PC, connect your BT headset with mobile phone, connect your phone to your PC with USB cable. now just open google and search for "how to use phone as a speakers" so u can choose from some apps out there |

Having the same issue here. Fatal1ty AB350 Gaming-ITX/ac + Ryzen 7 1700x on Windows 10. Everything working fine for over a year, then suddenly Windows can't find Bluetooth and USB devices. Logitech USB Unifying receiver not working. Bluetooth doesn't show in Device Manager at all (WTH?)
Very very strange. Flushed CMOS. No luck. Uninstalled and installed Intel bluetooth and USB drivers, no luck. Used Driver Booster to scan for newest drivers for everything and installed. no luck. Used Driver Booster to uninstall AMD USB 3.1 eXtensible Host Controller driver, BINGO! System suddenly activated Bluetooth and USB. Keyboard and mouse now works. Reboot the OS and then Bluetooth shows in Device Manager. Took me 5 hours. shaking my head. |

Your instructions worked like a charm.
Uninstalled the AMD USB 3.1. Now Bluetooth is working! Thank you.

Hi all!
having the same issue, but removing the AMD Extenstible USB 3.1 (Microsoft) does not works (also makes my keyboard stop working). Any other idea? Thanks in advanced. |

This works because uninstalling the USB controller removes power to the Bluetooth adapter. And since windows reinstalls the UBS controller again it start working like you hard reset the Bluetooth. Uninstalling Bluetooth drivers does not remove power to the Bluetooth since it is given by the USB controller. Reset the PC does not work as well since it does not remove power to anything in the PC, just restarts the CPU. A simpler fix was to turn off your computer and unplug it from the power source (since bluetooth has power even in standby). Basically you simulated a way to remove power to the Bluetooth adapter without turning off the PC. |

The official Bluetooth specifications state seven is the maximum number
of Bluetooth devices that can be connected at once. However, three to
four devices is a practical limit, depending on the types of devices and
profiles are used. Some devices require more Bluetooth data, so they
are more demanding than other devices. Data-intensive devices may reduce
the total number of devices that can be active at the same time. If a
Bluetooth device becomes slow to connect or does not perform reliably,
reduce the total number of connected devices.
