moncler - moncler sito ufficiale USB device not re

Mobile hard disk, U disk or mobile phone to download mp3, some times on the trip of a plug, a plug can be some times is


There are several possible reasons:

1, mainly due to unstable power supply or on the computer motherboard USB2.0 support is bad. For example: Intel (R) 82801 DB, Intel (R) 82801 EB, SIS 7001 chipset,ugg boots Insights into the quiet quiet quiet for, etc..

2, connected to the computer and printer or a USB data cable damaged if too long, there will be USB data cable length recommended no more than 2 meters.

3, now the computer will generally have 4 to 8 USB interface, but some computer installed Windows XP, USB interface, there will be instability, typically as USB mouse, USB keyboard inexplicable failure .

4, Front USB lines are wrong.

5, USB interface, insufficient voltage.

6, plug to be careful when reading and writing must not pull out, or you could burn the chip

the corresponding solution will have a variety, the kind of good to consider your situation, remedy.

1, in the Device Manager to disable the Universal Serial Bus Controller USB2.0 device.

2, disabled in the CMOS USB2.0 Controller.

3, if identified as failures caused by USB data cable, you can replace the standard cable.

disable Universal Serial Bus Controller USB2.0 devices, methods of operation are as follows:

1, the desktop , Figure 1 USB cable port on the computer should be able to correctly identify the printer port.

CMOS to disable USB2.0 Controller, operating as follows:

1, turn,moncler - moncler sito ufficiale, press the F10 key or the DEL key to enter the CMOS, as shown in Figure 2
Figure 2: CMOS


2, use the arrow keys on the keyboard pointing to state, made the changes select Figure 3 When the motherboard's USB cable and USB interfaces on the chassis front corresponding to the positive and negative phase reverse when such failures occur, and this is very dangerous, because positive and negative reverse is likely to make the USB device burned. So as far as possible the USB interface, rear chassis, but also fewer extension cords. Fracture may also be a problem, another USB port have a look.

USB interface to insufficient voltage. When the mobile hard disk connected to the USB port on the front is likely to occur when the system does not recognize the device failure. The reason is relatively large power requirements of mobile hard disk voltage is relatively strict, pre-interfaces may not provide sufficient voltage, of course, poor quality of power supply may also cause this problem. The solution is not mobile hard disk USB interface connected to the front, the replacement of poor-quality low-power external power supply or try to use the hard disk box, if able to do so.

motherboard and system compatibility issues. Oh the most famous of such failures is NF2 motherboard and USB compatibility issues. If you are in the NF2 motherboard encounter this problem, you can install the latest drivers and patches nForce2 special USB2.0, the latest operating system patches and patch the motherboard, or does not work, then try to refresh the motherboard BIOS generally resolved.

system or BIOS problem. When you disable the BIOS or operating system a USB device does not occur when the USB recognition in the system. The workaround is to open the device with the USB related options. F2 or DEL at boot is the key to enter the BIOS, to enable usb device select enable.

plug to be careful when reading and writing must not pull out, or you could burn the chip. XP, the taskbar icon for more USB devices, open the icon will appear in the list U disk device,replica mens watches Gave the girls have not marri, select the device to disable, then you can unplug the device, which would be more secure.
