Does USB 3 require a new case front panel and cable??

wkl_lau · 07-08-2009, 03:48 PM

Hi guys, i am thinking about building a new system using Core i7 + Asus P6X58(when available) because it has USB3. Now I just remember the case has front USB2, does it mean i will only have USB2.0 in front. Or is it independent from teh cable and front panel??

Thanks

Here a link on USB 3....
Universal Serial Bus - Wikipedia, the free encyclopedia

And here's a quote...Features

*USB 3.0 receptacles are compatible with USB 2.0 device plugs for the respective physical form factors. However, only USB 3.0 Standard-B receptacles can accept USB 3.0 Standard-B device plugs.

*The protocol uses Dual-simplex, over four additional wires, differential signaling separate from USB 2.0 signaling (thus six wires total) to achieve the full Superspeed 5.0 Gbit/s

*The bus power spec has been increased so that a unit load is 150mA (+50% over USB 2.0). An unconfigured device can still draw only 1 unit load, but a configured device can draw up to 6 unit loads (900mA, an 80% increase over USB 2.0). Minimum device operating voltage is dropped from 4.4V to 4V
