Windows device driver information for Micro-Star USB Enhanced Host Controller

The Micro-Star USB Enhanced Host Controller is created and manufactured by Micro-Star International, Adaptec Incorporated. A hi-speed USB host controller is already built into recent computers, while older computers can be updated with the hardware. A controller is not expensive and can be bought anywhere computers are sold. The hi-speed USB host controller is a card that can be easily installed into any accessible slot in the motherboard. The back-facing plate of the controller offers two or more hi-speed USB ports. To take advantage of USB 2.0 speeds, both the computer and the device connected into the USB port must comply with the 2.0 standard. A hi-speed USB host controller is not capable of making a USB 1.1 device operate at 2.0 speeds. Hi-speed controllers are backwards compatible, though, they fall back to the slower 1.1 standard for devices that need it.

Outdated Drivers?

Unless you update your drivers regularly you may face hardware performance issues.

To check your drivers you should manually verify every device on your system for driver updates

The Micro-Star USB Enhanced Host Controller is a register level interface which permits a host controller for USB or FireWire to interact with the Operating System of a personal computer. On the expansion card or motherboard controller, this engages a lot of custom logic, with digital logic machines in FPGAs plus analog circuitry controlling the high speed varying signals. On the software part, it needs a device driver which is called a Host Controller Driver, or HCD. One of the several advantages of USB ports is that they can function in a daisy chain. One hi-speed USB host controller can control many USB ports. If the computer does not contain enough USB ports for the requirements, a USB hub can be added for a few dollars. The hub connects into a USB port while presenting a “bay” of extra ports. Some devices, however, such as digital cameras or iPods may need a direct port or a powered hub. Powered hubs contain their own A/C adapters. It is highly recommended you run a free registry scan for and Micro-Star USB Enhanced Host Controller errors before installing any driver updates.
