The Intel P67 Express Chipset provides the USB controller for the 2.0 ports. The two
USB 3.0 ports are provided by the NEC* UPD720200 controller. The port arrangement
is as follows:
• Two USB 3.0 ports are implemented with stacked back panel connectors (blue)
• Six USB 2.0 ports are implemented with stacked back panel connectors (black)
• Eight USB 2.0 front panel ports implemented through four internal headers
All 16 USB ports are high-speed, full-speed, and low-speed capable. The USB 3.0 ports
are super-speed capable.
NOTES
Computer systems that have an unshielded cable attached to a USB port may not
meet FCC Class B requirements, even if no device is attached to the cable. Use a
shielded cable that meets the requirements for full-speed devices.
