Usb transmission speed optimization method public

Now everyone should be a USB flash drive, USB flash drive is generally transmitted using usb, but many users are responding to the slow transmission speed of usb, there is any way to solve this problem, in fact, the method Yes, let's see if you have thought of it. Recently, I used a mobile hard disk to copy several Hollywood movies on my computer. I found that the file transfer time of 400M movies took nearly 20 minutes. However, I used the computer to transfer system files more than 1G and it could not be transferred in 5 minutes. It is obvious that the transmission speed is poor. Too much.

I have recently reinstalled the system to troubleshoot the system, so I suspect that the USB driver is not installed, but the latest driver problem still exists, followed by inserting the removable disk computer to the right foot prompt "This device Can improve performance " this sensitive information, and finally found the cause and solve, share the solution below.

When it is found that movie files are transferred from a removable hard drive to a movie via USB, the first thing that comes to mind is to update the USB driver, because it is suspected that USB 2.0 is not used.

Firstly downloaded a driver wizard software, through the detection of the computer hardware found that there is no USB device driver to update, so I downloaded several USB2.0 universal drivers on the Internet, but either the installation failed, or The problem remains after installation, and the file transfer is still very slow.

Unplug the USB interface, connect the other USB port on the back of the host, plug in the USB device, the desktop right corner USB device will pop up "This device can improve performance" prompt.

At this point, it is obvious that the device is not using USB2.0, but is currently in USB1.0 transfer mode, it is no wonder that the transfer file will be so slow.

Then enter the device manager, check the USB driver device, and found that there is no USB2.0 driver inside, the following are two USB2.0 drivers that can be seen under normal computer conditions:
< How to enter the device manager: Where does the device manager open the device manager?

Device Manager display under USB 2.0 under normal conditions

The above is the normal situation of the computer USB2 under normal conditions. Drivers, but yesterday's friend computer started device management without the two USB drivers marked above.

Then why can't I find the USB2 driver in my friend's computer?

There are two reasons for this:

1.) The computer platform is too old, that is, the computer belongs to Very old platform, master configuration machine

2.) The BIOS has disabled USB2.0 function

The motherboard above 945 has fully supported USB2.0, and the current 945 has been eliminated. Years, unless the computer was very good before 2006, but the computer used now is almost not so old, although the friend computer is somewhat old, the motherboard is Gigabyte G41, and it is far above the 945 motherboard level, so the first This may be ruled out, then the problem is in the BIOS settings.

Then I restart the computer, press DEL to enter BLOS settings, click “Integrated Peripherals”, then find “USB EHCI Controller”, set to “Enadbled”, then press F10 to confirm save and exit can.

This will open the USB2.0 device, of course, this prompt will not appear again.

Because of the different brands, the settings in BLOS may be slightly different. Please refer to your motherboard manual for the specific operation method.

Turning on usb2.0 in bios

By restarting the computer after turning on USB2.0 in the BIOS, and then inserting the mobile hard disk, it is obvious that the USB device is recognized much faster and will not pop up. This device can improve performance & rdquo; prompt, then copy a 400M movie from the mobile hard disk to a friend's computer, found that the transfer is completed in less than 20s, so the usb transmission speed is resolved satisfactorily, how is it, is it very simple? I hope this article can help you solve the slow transfer of files on USB devices.

In this way, the problem of slow USB transmission speed is not solved. Of course, after the speed, how can everyone vary from person to person, the standard is different, but the effect is definitely there. You can also develop your own method. It is helpful to everyone.
