The Universal Serial Bus (USB) is the standard for wired extension. USB 'device classes' specify which features and which data formats the device supports.
Standard device classes include keyboard, mice, audio, video and storage devices. Read the Chrome Enterprise policy for USB devices.
A serial device is a device that provides serial communication interfaces, also known as serial ports. Through serial ports, information transfers in or out sequentially one bit at a time. While interfaces such as Ethernet, FireWire and USB also send data as a serial stream, the term serial port usually means hardware compliance such as RS-232, RS-485 or RS-422.
Examples of serial devices are microcontrollers, printers, modems and speciality mice. Read the Chrome Enterprise policy for serial devices.
Human Interface Device (HID) refers to the HID protocol; a standard communication with connected devices. Examples of HID devices are keyboards, mice, headsets and game controllers.
Sites can use HID to access buttons, turn LEDs on and off, or mute and unmute microphones. Read the Chrome Enterprise policy for HID devices.
