USB 2.0 Support
The Desktop Board provides 14 USB 2.0 ports (eight ports routed to back panel
connectors and six ports routed to three onboard headers). USB 2.0 ports are
backward compatible with USB 1.1 devices. USB 1.1 devices will function normally at
USB 1.1 speeds.
USB 2.0 support requires both an operating system and drivers that fully support
USB 2.0 transfer rates. Disabling Hi-Speed USB in the BIOS reverts all USB 2.0 ports
to USB 1.1 operation. This may be required to accommodate operating systems that
do not support USB 2.0.
Serial ATA Support
Intel Desktop Board DP55WG supports six onboard 3.0 Gb/s Serial ATA (SATA)
channels via the PCH.
The Desktop Board includes a SATA drive activity indicator (a blue LED) shown in
Figure 3.
