What should I do if the Win7 computer USB interface cannot be used?

Recently, a user has encountered a strange problem, that is, the mouse can not be used, originally thought that the mouse is broken, but after switching to a new one, the connection to the computer is still useless, and the hardware driver on the computer cannot be successfully installed. There is no response to plugging in other USB jacks. How can we solve this problem?

Online inquiry, this problem is said to be a suspended animation of the USB interface, due to frequent hot swap. When the old mouse is broken, is it equivalent to hot swap? Follow the prompts, I started to repair:

1, first open the device manager, find the corresponding device:

2, according to the network method, find the corresponding USB port, it is said that each device corresponds to A string of characters:

3, but how can I remember that name? Still use my soil method, one experiment, unload one by one, which one is unloaded, the red light of the mouse bottom plate is off, that is the corresponding USB interface.

4, if the character is poor, big deal will unload all the USB, it will definitely include the problem. After uninstalling, restart the computer, the computer will automatically re-install all USB drivers, then plug in the mouse, the computer recognizes the installation, get it!

Just a sigh of relief, the screen pops up a warning window: "update· exe encountered a problem, close the program", this is obviously an automatic update of the problem, open the automatic update, view the settings, no problem what. I crossed the warning window and jumped out after a few minutes.

5, for this, we open the task manager, looking for the relevant process:

6, but, there is no "update· exe" process, almost to think that this method is not reliable At this time, the error warning appears again, and the corresponding process appears in the process list, decisive right click to open the corresponding folder:

7, the original is the application of the PC version of the program, this program is I used wp7 mobile phone, it has been useless for a long time, delete, warning window no longer appears, troubleshooting.

After the above repair operation, we summed up the point that no matter what program error, we should not simply guess from the name, it is best to open the task manager without closing the error prompt. Then find the corresponding program to repair, the only way to get the right medicine.
