USBHUB is a computer peripheral product that can expand one USB port to 2 or more. (Recommended study: phpstorm)
is only suitable for peripherals that do not have high power supply requirements. No matter how many points are divided, it is only the power supply of a U port, so the more divided The more the power supply of each branch U port is, the smaller it will be. If the peripheral device has a large demand for power supply, it will not be able to meet the requirements of the peripheral device. Naturally, the peripheral device will not be able to be used due to insufficient power supply.
Yes This won't happen on the computer side, it will only affect the connected device.
The USB extender will just expand your USB interface to several more interfaces. The USB interface has unified technical specifications, outputs 5V voltage, and the output current is determined by the USB interface version. , for example, the theoretical output current of version 3.0 is 2A, and the output current of version 2.0 is 500mA.
The actual output current of such an expanded USB interface is less than the theoretical value of the standard USB output current. If a USB interface is connected alone, the current received by the device is large, But the USB extender also When multiple USB devices are connected, the total output current remains the same. Connecting USB devices that require high current will affect their working status, so the extender should connect devices with low current as much as possible.
Transfer computer desktop information to another display device (VGA input) through the USB interface for display on the same screen, or use another monitor as a display extension for this host, and then display different applications on the two screens at the same time software. For example, if you browse a website on one monitor and create an Excel spreadsheet on another monitor, the two tasks can be performed at the same time (full screen) without delaying or affecting each other.The above is the detailed content of Disadvantages of usb extender.
