2. If the large-capacity mobile hard disk is not recognized, it is recommended to use the "one-to-two" connection method. Usually the USB data cable of the mobile hard disk has two connectors, both of which are connected to the USB interface of the host.

third solution:

1. At present, computers are basically compatible with various USB devices, but it cannot be ruled out that some USB peripherals are incompatible.

What to do if there is no response when the USB is plugged into the win7 system computer

The solution is as follows:

1. Driver issues:

1. Use the download driver life tool to solve the problem. The peripheral driver function of driver life (the official definition of driver life, all devices connected through USB are defined as peripherals) actually accurately recognized that the U disk driver was not installed, and then The editor tried to click "Repair Driver". After about ten seconds, the USB drive letter appeared successfully, which solved the problem of the USB drive not responding when inserted into the computer.

To sum it up in one sentence, what should I do if the USB flash drive does not respond when plugged into the computer? In fact, it is very simple and can be solved. Using the peripheral driver function of Driver Life 6, you can fix the driver problem that does not respond when a normal U disk is inserted with one click.

3. Click Repair Driver to solve the problem of the U disk not responding when inserted into the computer

4. Repairing (repairing time is usually a few seconds to more than ten seconds)

5. The driver is finally normal.

2. If it is not a driver problem and there is still no response after inserting the USB flash drive into the computer after ensuring that it is normal, then we can try other solutions.

1. Try changing the USB interface. If it is plugged into a USB extension cable or the front USB panel of the chassis (which may cause insufficient drivers), plug it directly into the USB port of the motherboard. In addition, some weird notebooks, Some USB ports can be used when plugged into a mouse and keyboard, but they cannot be used when plugged into a USB flash drive;

2. Check whether the motherboard USB 3.0 driver is installed. Win7 and XP do not come with USB3.0 driver by default. If the driver is not installed, this interface cannot be used;

3. Try changing to a normal USB flash drive to see if the motherboard has compatibility issues with this USB flash drive...
