USB 3.0 Type-A (J6)
The USB 3.0 Type-A port supports both USB 3.0 and USB 2.0 speeds on connector J6.
J6 also provides a 5 VDC level on the VBUS pin that can source up to 900 mA by passing through the current limiting load switch EU3. USB loads that exceed the 900 mA limit can have unpredictable behavior. Device load on the Type-A connector is to be considered in total platform power needs when selecting power supply solutions.
