The But you can use the module to distinguish the color can be connected to the final switch. 6-core, and 12-core panel may be fiber-optic panel FO, only the use of fiber with a few cores of the core. The general panel is also divided into only a single mouth and so on. Is positive solution! The The
This shows that your computer's USB interface power shortage, this situation usually appears in the early computer, because at that time the computer USB interface are USB1.1 (now called USB2.0fullspeed), the voltage requirements are relatively low, generally 4.5 -5V, but actually can achieve very little 5V (especially in the notebook). USB devices are basically USB2.0 interface (now called USB2.0highspeed), the voltage requirements are relatively high, usually between 5-6.5V. Because a lot of USB devices are directly through the USB interface to take power to use, so if the voltage is not enough, that the equipment may be fatal blow, if you use the mobile hard disk may also damage the hard drive motor, resulting in equipment scrapped The USB hub and the role of ordinary household use more like plug, is to use an interface to copy more USB interface for use. But the defect is obvious, because the computer voltage control more accurate, a USB interface power supply is rated, not because you use the USB hub to increase the voltage, if you use this hub at the same time the use of large power consumption Of the USB device will appear when the lack of power supply situation, while causing equipment failure. There are two ways to solve: First, do not connect two USB devices on the hub at the same time (note that this is not used, but the connection, even if you do not use at the same time, but as long as the connection is the same power consumption) to ensure power supply adequate. Second, for a USB hub can be an external power supply, which is the most fundamental way. Even if the computer USB interface itself is not enough power supply.
