USB port power shortage, how and deal with?
Solution: . the USB device will be connected to the motherboard on the different USB port; . with one end with a double USB plug extension cord, the two plugs are plugged into the motherboard USB port (one dedicated to take power); . with a PS / 2 (that is, the mouse round mouth) plug USB extension cable (PS / 2 plug for power); . with a power supply USBHUB (a lot of points, but also pay attention to each port only A device and do not add an extension line). ,,,,,,, each USB port to limit the power supply to 500mA, after more than may automatically close the interface.
This is no better solution, you can try to replace the high-power power - high power refers to the rated power, not the maximum power - do not let you flicker. In addition, some motherboard design is flawed, resulting in insufficient power supply usb, as in addition to the motherboard for no good solution to satisfied please adopt
