Computer USB interface, how to deal with bad, USB device is hidden when more
Is the motherboard is on the USB port or peripheral port, if it is more trouble on the motherboard, or to the professional maintenance of it, if it is peripherals you look at the connection and the motherboard data cable socket is loose, check the line, If not, buy a good quality USB peripherals to replace it.
Such as the host interface, then no way to deal with only a good point of the line used to connect usb equipment is not only can add a usb card in the machine, after all, for the board too expensive
As far as possible into the host behind the USB interface (desktop computer), notebook, then no way, front-end USB interface is the motherboard's USB interface extension cord to take over, so generally very unstable, vulnerable to external factors. For example, magnetic fields, mobile phones and other items of the impact of relatively large. So it is recommended that you try to insert the back. Here to tell you a little knowledge: what is the signal? There are two kinds of signals, one: analog signal, two: digital signal. Front-end to accept the analog signal, and the host behind the USB interface is directly connected with the motherboard, to accept the digital signal, digital signals are generally not susceptible to external factors, even the phone is also nothing, so I suggest you go to the back of the truth Is this, understand it?
