Solution to USB interface power shortage

Nowadays, USB interfaces are frequently used. Although this type of device is very simple to use, you must master some usage skills to make good use of it, otherwise, there will be many strange faults, which will affect the use efficiency of USB devices. This is not the case. The most common problem encountered when using a USB device is the power source-the power supply shortage problem. to effectively solve the fault of insufficient power of the USB interface, this article specifically summarizes some countermeasures, hoping to help you!

[Blocked Advertisements] How to identify USB Power Insufficiency

Generally, when a USB device is inserted into a Windows 2000 or later system, it can be automatically recognized by the system and work properly. After many USB devices with insufficient power are inserted into the computer system, the following failures often occur:

1. The computer system can automatically identify the USB device and install the driver of the device normally. However, after the driver is installed, it cannot access the content of the device, this is because the drive letter of the device cannot be found or the device cannot be used.

2. The computer system cannot automatically identify the USB device. The signal indicator in the USB device is not on or is abnormal, and even the USB device emits unusual sound, for example, if the hard drive of the USB interface is not powered enough, the hard drive will often be "choppy.

3. When a USB device is not connected, the system can be started normally. However, after a USB device is connected, the system cannot be started normally and an error message is displayed, for example, the system startup file cannot be found, or the System Startup File is damaged.

4. Even if the computer system can automatically identify the USB device, and the content of the USB device can be accessed, it is obvious that the access speed of the USB device is much slower than usual, even when a USB device is working for a long time, an access error occurs suddenly, or the computer system crashes for no reason.

Therefore, when you find that the above fault exists when using a USB device, you must check its power source to avoid detours during troubleshooting!
