What is USB 2.0?Finalized in 2001, Universial Serial Bus (USB) 2.0 is a complete overhaul of the Universal Serial Bus input/output bus protocol which allows much higher speeds than the older USB 1.1 standard did. The goal of the new serial bus is to broaden the range of external peripherals that can be used on a computer. A hard drive can easily hit the USB 1.1 bottleneck whereas it now becomes more 'usable' under USB 2.0 conditions.To those people who found us via search engines, USB 2.0 should neither be called 'USB2' nor 'USB 2'. 2. How do I know if my PC has USB 2.0?You can identify whether your PC has Hi-Speed USB or not relatively easy. Open Device Manager and expand the Universal Serial Bus section. There should be an "Enhanced" USB host controller present. Windows 98 systems may use a different name, because Hi-Speed USB drivers in these operating systems are not provided directly from Microsoft (Windows ME, 2000 and XP get their drivers through Windows Update). These drivers are provided by the manufacturer, and may carry the maker's name (i.e. ADS, Belkin, IOGear, Siig, etc.). There should also be two "standard" version USB host controllers present as well. They are embedded in the USB chip which routes the differing USB speeds accordingly without user intervention. There are currently 7 manufacturers of the Hi-Speed USB host silicon themselves: ALi (Acer Labs) Intel NEC SiS VIA nVidia (shows as "Standard" controller) Philips Any other brand name that appears in Device Manager would likely be an add-in Hi-Speed USB PCI card. The makers above do not make add-in cards, but they do make the chips that are used in them.3. What happened to USB 1.1?USB 1.1 allowed a maximum transfer rate of 12Mbits/second. It is now obsolete, but both of its speeds (1.5Mbps & 12Mbps) are being adopted into USB 2.0, and they are now called Original USB officially. Though some manufacturers label their products Full-Speed USB. Note that this seems a bit deceptive as it's easy to mistake Full-Speed for Hi-Speed. You won't be fooled from now on as you now aware that Full Speed USB is only 12Mbits/second where Hi-Speed USB mode is capable of a much faster 480Mbits/second.Traditionally, USB mice and keyboards only need 1.5Mbps to function; exceptions are gaming input devices that require 12Mbps, and they include the Logitech G5, G7, G15 and Razer Copperhead. These higher-end gaming products send way more location feeds thru USB; hence, more bandwidth is required. Generally, the performance levels (1.5Mbps & 12Mbps) are grouped under 'Original USB' by the USB Promoter Group.The logo shown on the right is authorized by the same organization to the vendors for use on their products should</blockquote>
