How do I know if my PC has USB 2.0? Add Your Notes
You can identify whether your PC has Hi-Speed 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 6 manufacturers of the Hi-Speed USB host silicon themselves:
ALi (Acer Labs)
Intel
NEC
SiS
VIA
nVidia (shows as “Standard” controller – see illustration above)
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.
