This article lists the Universal Serial Bus (USB) host controllers supported in Windows 98 and Windows Millennium Edition (Me).

Windows 98 and Windows Me support two USB host controller standards:

• Open Host Controller Interface (OHCI)
• Universal Host Controller Interface (UHCI)

Windows 98 and Windows Me include drivers that support each of these hardware standards.

Windows 98 and Windows Me include drivers for the following OHCI USB host controllers:

• Symbios
• RealTech (based on OPTi hardware)
• CMD Technology (except the REV_04 version)
• Silicon Integrated Systems
• OPTi
• Ali
• National Semiconductor
• NEC

Note that other OHCI host controllers that comply to the OHCI specification are supported by Windows 98 as a standard OHCI USB host controller.

UHCI

Windows 98 and Windows Me include drivers for the following UHCI USB host controllers:

• Intel
• VIA Technologies

Note that other UHCI host controllers that comply to the UHCI specification are supported by Windows 98 as a standard UHCI USB host controller.

Additional Information

Most of these manufacturers provide the USB controller as part of the motherboard. Currently, Symbios and RealTech provide USB controllers as Peripheral Component Interconnect (PCI) add-on cards.

Note that not all versions of all controllers are supported by the drivers included with Windows 98 and Windows Me.
