  • Finally, I looked at this program called VIA XHCI Host Controller that came with the drivers for my MOBO. I did a Google search (which I had.
  • Via is a chipset, not a full card manufacturer. What kind of adapter is this? What is the full make and model? Did you go to the manufacturer's website and look for drivers? It sounds like you're just checking for updates in Windows Device Manager. If Windows can't automatically find a driver, then you'll get the message you're seeing.

  • Compliant to Universal Serial Bus 3.0 Specification Revision 1.0
  • Compliant to Universal Serial Bus 2.0 Specification
  • Compliant to eXtensible Host Controller Interface (xHCI) Specification Revision 0.96
  • Support Legacy USB Function
  • In-house USB PHY employs advanced CMOS process to reduce power consumption
  • Compliant with PCI Express Base Specification 2.0
  • Support Battery Charging Specification
  • Firmware upgrade options include integrated firmware in system BIOS

Software:

  • Initial Driver Support for Windows 7, Vista, and XP
  • USB Attached SCSI Protocol (UASP)
  • Support various Linux kernels
Host

Target Applications:

  • Desktop / Notebook motherboard on-board controller

  • Replaces UASP AP with revision 1.0.0.12.
  • Adds workaround in setup program for following two items:
    • Disables performance enhancement for solving CPU utilization too high issue.
    • Works around UASP client driver cat files for separate OS issue.

Universal Serial Bus (USB) is an input/output port standard for computers and digital equipment, which allows easy transfer of data via a direct connection or cable. The original USB standard version has been superceded by hi-speed versions. A hi-speed USB host controller refers to the hardware inside the computer that provides hi-speed USB functionality to the ports.

USB first hit the market in November 1995, but the new standard had compatibility problems. These bugs were addressed and the subsequent USB version is now referred to as “original” USB 1.1. The data transfer rate (DTR) for USB 1.1 was impressive at 12 megabits per second (mbps), and it was intended to replace slower parallel and serial ports for peripheral devices. The first devices to be widely adopted for USB ports were keyboards and mice. Printers, scanners, external tape drives and other devices followed.

As demands for faster data transfer increased, a newer version of USB answered the call. USB 2.0 boasts maximum data rates of 480 mbps, 40x faster than original USB. Computers that supported the old standard required a new hi-speed USB host controller to take advantage of the faster speeds. Devices made for the new 2.0 standard, such as memory sticks and digital cameras, would default to the old, slower transfer speeds if plugged into a computer with a USB 1.1 controller installed.
