what is the number of USB Host connections I can use with armstoneA9r2? In Hardware Documentation V 0.4 page 5 I see 4 x USB Host. On page 6 I see 3 x USB Host.
The armStoneA9r2 has 4 USB Host ports. Two are on the Dual USB A connector, one is on a pin header behind the USB connector and one on the miniPCIe connector.
