USB - Universal Serial Bus

The Intel® Joule™ module provides two USB2 and one USB3 port through the board-to-board connectors:
  • USB2 port 0: Used primarily in device mode, also for updating the firmware through the DnX protocol, port 0 also provides signaling of host mode through the USB ID pin.
  • USB2 port 1: Used with USB3 port 1 as a backwards compatible USB host port for (keyboard, mouse, HUB) accessories
  • USB3 port 0 and 1
  • Type-C
The main uses for USBs are to connect hubs, keyboards, and mice when the module is acting as the USB host, or allowing the module to act as a device when communicating with a host.
It is necessary to operate in USB device mode to perform firmware updates.

Product and Performance Information

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
