Intel Desktop Board DH61AGL Technical Product Specification • Panel Power Sequencing: allows the system integrator to adjust panel sequencing parameters, if necessary. • LVDS Spread Spectrum Control: allows the system integrator to adjust spread spectrum for the LVDS interface. NOTE Support for flat panel display configuration complies with the following: 1. Internal flat panel display settings will not be overwritten by loading BIOS setup defaults. 2. Internal flat panel display settings will be preserved across BIOS updates. 1.5.3 USB The PCH contains up to two Enhanced Host Controller Interface (EHCI) host controllers that support USB high-speed signaling. High-speed USB 2.0 allows data transfers up to 480 Mb/s. All ports are high-speed, full-speed, and low-speed capable. The Intel H61 Express Chipset provides the USB controller. The port arrangement is as follows: • Four ports are implemented with stacked back panel connectors • Five front panel ports implemented through three internal headers (two dual and one single header) • One port implemented in the PCI Express Half-Mini Card slot NOTE 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. For information about The location of the USB connectors on the back panel The location of the front panel USB headers Refer to Figure 11, page 42 Figure 12, page 43 24

USB
The PCH contains up to two Enhanced Host Controller Interface (EHCI) host controllers
that support USB high-speed signaling. High-speed USB 2.0 allows data transfers up to
480 Mb/s. All ports are high-speed, full-speed, and low-speed capable.
The Intel H61 Express Chipset provides the USB controller.
The port arrangement is
as follows:
•
Four ports are implemented with stacked back panel connectors
•
Five front panel ports implemented through three internal headers (two dual and
one single header)
•
One port implemented in the PCI Express Half–Mini Card slot
NOTE
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.
