www.BlackViper.com: Windows 7 Services 411 - Human Interface Device Access

Human Interface Device Access

Default Description:

Enables generic input access to Human Interface Devices (HID), which activates and maintains the use of predefined hot buttons on keyboards, remote controls, and other multimedia devices. If this service is stopped, hot buttons controlled by this service will no longer function. If this service is disabled, any services that explicitly depend on it will fail to start.

Additional Information:

You may not have any peripherals that require this service. If one of yours magically does not function anymore, set it to automatic. Namely, scanners with function buttons (fax, copy) or even an "Internet" keyboard with volume or play controls. Most hardware, however, comes with its own software drivers to use the functionality this service provides.
