The Universal Serial Bus Controller (USB controller) plays a crucial role in computer systems, primarily affecting and managing devices related to USB interfaces. The following are the main device types and their related functions affected by Universal Serial Bus controllers:
- External storage devices
Mechanical hard drive: Although USB controllers do not significantly affect the recognition of mechanical hard drives under normal circumstances, improper operation of USB devices or USB controller malfunctions may result in the computer being unable to recognize or access the mechanical hard drive.
USB flash drive: The USB controller directly manages the connection and data transfer of the USB flash drive, ensuring stable and efficient data transfer. - Input device
Keyboard and mouse: These common input devices are connected to the computer through a USB interface, and the USB controller is responsible for handling their communication with the computer, ensuring that input instructions can be accurately conveyed. - Output devices
Printer: Many modern printers support USB interfaces, and the USB controller is responsible for handling data transfer between the computer and the printer, ensuring that printing tasks can be completed smoothly. - Multimedia devices
Cameras and audio devices: These devices are often connected to computers through USB interfaces, and USB controllers are responsible for data exchange between them and computers, supporting functions such as video recording and audio input/output. - Other USB devices
Mobile devices (such as smartphones, tablets, etc.): When these devices are connected to a computer through a USB interface, the USB controller is responsible for handling functions such as data transfer and charging between them.
Sensors, card readers, etc.: These devices are often connected to computers through USB interfaces for various data acquisition and reading tasks.
summary
The Universal Serial Bus controller mainly affects and manages various devices related to USB interfaces, including external storage devices, input devices, output devices, multimedia devices, and other USB devices. It ensures that these devices can connect and transfer data with computers stably and efficiently, improving the usability and functionality of computers. Meanwhile, with the continuous development of technology, the new generation of universal serial bus controllers has significantly improved in performance, power consumption, and compatibility, supporting more types of USB device connections and more advanced data transfer functions.
