Re: usb problem

You shouldn't need the USB driver 2.0 from mercury because windows installs this with SP2. Suggest you un-install what you installed from mercury & update your version of windows (completley), through "Windows Update". Once windows is all updated & you have finished with a reboot. Plug your pen drive in a opened usb port. Open windows explorer. Scroll down & you should see an icon (left side of explorer), thats named like, Removable Disk. Give windows time to see the device. After a few minutes if your pen device does not show up try another usb port. One you know does work. If after a couple of minutes go by & you still don't see the device listed in explorer I would say the device is defective. Your Mp4 uses a cable to connect to the usb. Try connecting to another PC's usb port. It is possible the cable is dirty or bad.

your problem is kind of complicated. Check if you have a defective usb flash drive or an usb connector by doing so:
  1. Try other usb flash drive. If it solves the problem you have a defective flash drive
  2. Try to plug in to other usb port. Observe each port. If you see that you have a problem with your usb ports, buy a new usb port card

Cannot copy any file like movie in pendrive. everytime when copying any movie in pendrive it will disconnect automatocally,and after sometime automatically reconnect. what do i do???


try to check your usb port, try another pen drive, maybe the pendrive is faulty, if not the pen drive is faulty, check your usb port. maybe your pendrive is 3.0 and your usb port is 2.0 only.

Usb port don´t work, if you connect this says "no se reconoce dispositivo usb" but sometimes this work perfectly

it happened probably due to a virus. Has you scan your computer with anti virus. I suggest you use the Kaspersky virus remover tools. If the problem on your usb ports are still repeated, it is possible that you put things like USB cable, pen drive or the like that is put into the usb port or usb you probably can not be fully functional.ways to overcome this problem is much better to install a USB card to pci slot on your motherboard.

For any computer there will be at least 4 usb ports. 2 at the front and other 2 at the back side of cpu. If any one is not recognizing then insert it in different usb port. If any of the port is not working then install the driver for your usb port. Download the usb driver from the below link.

Thank you......

Front Side USN dows not work in ASUS M2N MX SE

The front side port may be a "low power" USB port, it may be possible to "power" this if there is the capacity to connect a power cable to the front panel USB adapter, or there may be an aux power socket to plug into on the motherboard.

Front side USB port is not working

On some computers the front usb ports are like a usb hub, they don't have enough power to power up a hard drive.
