I am having the same problem as the OP, even down to the reinstalling of drivers every time i connect
Dongle: Asus BT-400
Location: Front USB port next to my other BT (generic Rocket Fish) used for my DS3
Made by Nintendo: Yes
Connection: Windows BT device config, however if i do not open dolphin within seconds after connection it will immediately lose connection, Dolphin MUST be open when i connect, or shortly there after
