- 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.
VIA USB 3.0 eXtensible Host controller card don't work after update til Fall Creators update. Have tried to find new drivers for it, but no succes.
The VIA VL800 is a single chip USB 3.0 Host controller, which enables a PCI Express equipped platform to interface with USB Super-Speed (5 Gbps), High-Speed (480 Mbps), Full-Speed (12 Mbps), and Low-Speed (1.5 Mbps) devices. The root hub consists of four downstream facing ports enabling the simultaneous operation of multiple peripheral devices.
The VIA VL800 complies with the Universal Serial Bus 3.0 Specification and Intel’s eXtensible Host Controller Interface (xHCI), and is fully backward compatible with USB 2.0 and 1.1 specifications, ensuring seamless connectivity of legacy USB devices. The VIA VL800 has a PCI Express 2.0 x1 interface that is backwards compatible with PCI Express 1.0 and is perfectly suited for both PC Host and Add-In Card applications.

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 The original USB standard version has been superceded by hi-speed versions.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.
