mainboard, adding an usb nano hub?

[heocb]

pine64, can you make an estimate of what it would cost to add an usb nano hub on the
mainboard? Or design the mainboard such, that people themselves could
add an usb nano hub? I want to be able to connect an
usb wifi card to the mainboard. Other people might find ways to
utilize an usb hub.

No plan to add an USB hub due to mainboard PCB limitation. For expansion, please consider using the i2c locates on pogo pins.
