Frequently Asked Questions
Does this hub add HDMI or card readers?
No — this is a USB-only hub. For multi-function expansion with HDMI, SD, and Ethernet, see the Surface Pro 3 4-in-1 Adapter or Surface Pro Ethernet Adapter.
Will it power bus-powered external drives?
Yes, typically. Heavy-draw 2.5" spinning drives may benefit from a separate powered hub if the Surface Pro 3's single USB port can't supply enough current.
Do I need drivers?
No. Windows recognizes the hub automatically.
Does it work on a Surface Pro 4 or newer?
No — the connector shape is specific to the Surface Pro 3. For newer Surface Pros, see the Surface Pro 4 USB Hub.
