Any device can be a USB HID class device as long as a designer meets the USB HID class logical specifications. This is not to say that there is no need to ship drivers for these devices, nor that an operating system will immediately recognize the device. This only means that the device can declare itself under the human interface device class.
BadUSB is a computer security attack using USB devices that are programmed with malicious software. [2] For example, USB flash drives can contain a programmable Intel 8051 microcontroller, which can be reprogrammed, turning a USB flash drive into a malicious device. [3] This attack works by programming the fake USB flash drive to emulate a ...
Microsoft Mouse and Keyboard Center supports USB and Bluetooth devices; it does not support (automatically detect and configure) PS/2 and some older USB devices, [1] as detailed in the following sections. Most are still supported in the latest corresponding versions of Intelli Type Pro and Intelli Point, although they can no longer be ...
PS/2 did not typically support plug-and-play, which means that connecting a PS/2 keyboard or mouse with the computer powered on does not always work and may pose a hazard to the computer's motherboard. Likewise, the PS/2 standard did not support the HID protocol. The USB human interface device class describes a USB HID.

However, the USB boot keyboard class (designed to allow the BIOS to easily provide a keyboard in the absence of OS USB HID support) only allows 6-key rollover. Some keyboard peripherals support only the latter class, and some OSes may fail to switch to using the full HID keyboard class with a device after boot. [14]
A computer keyboard is a built-in or peripheral input device modeled after the typewriter keyboard [1] [2] which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches.
It has been succeeded by Microsoft Mouse and Keyboard Center, which combines IntelliType with IntelliPoint. IntelliType supports all known Microsoft keyboards (including those that are shipped as parts of desktop sets, as well as entertainment keyboards – i.e. those that are intended for Media center ).
