Review on Wireless Bluetooth USB Adapter For Gaming Consoles And PC: MAYFLASH Magic-S Ultimate, Compatible With PS4, Switch, Xbox Series X & S, PS5, MacOS, Windows, Raspberry Pi And More by Paul Milonas

Works like a charm, easy to use, fully automatic.Few things: - LED color means the system it's plugged in (not the native system of the controller). This model detects it automatically, so you actually never need to switch modes manually - Paired (or plugged) controller won't be able to wake your Switch, as USB is not powered in sleep mode. So you will have to wake it using power button on Switch itself or home on joy-con or pro controller, let the whole deal reconnect and only then your other controller will be operational - This device adds some neat functionality: you can control rumble intensity (7 levels), you can swap A with B and X with Y ( Switfh vs Xbox layout), you can tune dead zone (5% by default). Use combinations of buttons from the manual - Device's USB is not the same as another USB on Switch. You won't be able, for example, connect audio dongle through this device. This is important because some dongles won't fit simultaneously with this device and you will have to plug it in USB 3 (blue port on inside of the dock) and you won't see device's led, also you won't be able to press sync button on the device easily - However, you can power things through this device (when Switch is awake), for example, charge your phone. Just no data other than connecred controller's inputs
