I have a new Tello, Gamesir T1S controller, Samsung S7 phone, and Samsung Gear VR headset (HMD) for FPV. I would like to have direct USB connections between all devices (no Bluetooth). Problem is I need to connect the phone to two devices -- Gamesir T1S and GearVR HMD. Do these devices follow USB protocol conventions so that a USB "splitter" can be used? Can I come out of the phone into a Y splitter that goes to the controller and the headset, and it will work? Thanks!
