I bought this cheap powered multiport usb 3.0 hub for my setup :

With power supply from the adapter i finally can successfully make my setup works (Surface Pro 3, Roland Integra 7, Yamaha PSR SX900, vArranger USB Key).
When i use my Asus gaming laptop, i do not need to use the power adapter, but when using Surface Pro 3, i have to use the power adapter that came with the hub.
Thank you for your info bluebeat!
