THREE USB Connectors: JUSB1, JUSB2 & JUSB3 (K7T266 Pro2-U, K7T266
Pro2-RU)
If your mainboard comes with three USB pin headers along with the
NEC USB 2.0 controller, two of the headers comply with high-speed USB 2.0
specification and one is compliant to USB 1.1 specification.
USB 2.0 technology increases data transfer rate up to a maximum
throughput of 480Mbps, which is 40 times faster than USB 1.1, and is ideal for
connecting high-speed USB interface peripherals such as USB HDD, digital
cameras, MP3 players, printers, modems and the like. It is not recommended
to connect low-speed USB legacy keyboard and mouse to the USB 2.0 ports.
You should connect the USB legacy devices to the USB rear ports.
The mainboard can offer four USB 1.1 ports and four USB 2.0 ports.
