By default, Naon implements 3 USB interfaces:
- USB0
- internal connection: this port refers to USB0 interface integrated in DM8148 processor
- speed: high
- mode: OTG
- signals: DP, DM, ID, VBUS, DRVVBUS
- USB1
- internal connection: this port refers to downport #1 of on-board hub; upstream port of hub is, in turn, connected to DM8148 USB1 port
- speed: high
- mode: host
- signals: DP (hub), DM (hub)
- USB2
- internal connection: this port refers to downport #2 of on-board hub; upstream port of hub is, in turn, connected to DM8148 USB1 port
- speed: high
- mode: host
- signals: DP (hub), DM (hub)
On request USB1 port of DM8148 can be routed externally, replacing on-board hub. In this case USB1 and USB2 ports mentioned above are replaced by this port:
- USB1
- internal connection: this port refers to USB1 interface integrated in DM8148 processor
- speed: high
- mode: host or device (mutually exclusive and selected by software)
- signals: DP, DM, VBUS, DRVVBUS.
