Why does Bluetooth turn off on iMac when USB drives are connected?

Question

Bluetooth

Good afternoon!
Disturbs and irritates one moment in iMac - bluetooth turns off. It was noticed that this happens when the USB ports are loaded (connecting many different devices). So is there an addiction to this or is it paranoia?
I tried all the methods of treatment that are described on the Internet, but they did not solve the problem. We save ourselves by rebooting the computer or reconnecting (it happens that the bluetooth is available for reconnection, and sometimes there is no adapter at all). Basically, I need your advice.
ps the only thing I did not do was not update the system, but did everything else (reboots in different modes, deleting plist and resetting the module)

Answer 1

Take it to the service, it's not normal. You can try to get around the problem by using an externally powered USB hub.
