USB 1.1 full-speed host:
• Support series：NUC442/472 series, M452/M453 series, NUC505 series
• Compliant with Open Host Controller Interface (OpenHCI) 1.0
• Supports Control/ Bulk In/Out /Interrupt/Isochronous transfer types
• Supports full-speed (12 Mbps) and low-speed (1.5 Mbps) USB devices
• Supports an integrated root hub
• Supports USB master/slave port (OTG function).
• Supports power control and overcurrent detection
• Supports DMA instant data transfer

On-The-Go (OTG):
• Support series：NUC442/472 series, M452/M453 series
• Configurable operating modes:
- Configured as a host
- Configured as a device
- Determined in accordance with ID: the USB_ID signal determines USB as the host (USB_ID is low potential) or the device (USB_ID is high potential); HNP and SRP protocol are not supported.
- OTG device: USB_ID signal determines USB as A device (USB_ID is high potential) or B device (USB_ID is high potential); HNP and SRP protocol are supported.
