updated windows8.1 found that their own serial cable can not be used! Baidu found that many friends have such problems, I tried a variety of online search for usb to serial port error method but did not solve, and finally found that in the driver point properties have error code 52 prompts, and later through the windows official forum The guidance of the great gods has resolved the problem. PS: This problem has been plagued for half a month. It also cost 50 oceans to buy a new line T^T. . .
1. Because it has been fixed now, it is more troublesome to reproduce the fault, so the screenshot is indicated. The driver with the yellow exclamation mark appears, the right-click property will be displayed in the device status box. Because of the error such as digital certificate, the code is 52.
2, start solving the problem: press the windows key +X+A Run cmd as an administrator and enter the command: sfc /scannow, which is used by Windows to detect the system integrity command.
3, (Because your computer has been repaired, the picture is the same on the computer, the content is the same), during the detection process or after the end, it will appear "resource protection found damage" File but some files cannot be repaired. CBS.Log windir\\Logs\\CBS\\CBS.log", OK starts to solve this problem!
4, the above situation occurs, also enter in the cmd running admin rights: DISM.exe /Online /Cleanup-image /Scanhealth, press the Enter key; ) DISM.exe /Online /Cleanup-image /Restorehealth, press Enter. After completing the above fix, reboot!
5. After rebooting, open the device manager and check the driver again. The yellow exclamation mark disappears! Re-plugged the serial cable several times, no exclamation point. PS: If it has not been resolved, don't worry, continue to check step by step, and what error the system gives, solve this error. Mainly steps, step by step, don't worry, I have solved this problem for half a month! I hope to help you!
