USB devive not recognised

Všechny reakce

  • Hi,

    What have you done before the problem happen? Did you update your system, driver or install some software?

    Here is something you can check:

    1. Unplug the keyboard and plug it in to other computers, seeing if it can be recognized.

    2.Changed another port to plugin, seeing if it can be recognized.

    3.Open Device Manager, checking if the external keyboard exists there. If it exists there, then try to update the driver(keyboard, Universal Serial Bus controller). If it shows as an unknow usb device, you have to manually install or update the driver of it.

    4.Open Device Manager, expand USB Serial Bus Controllers, right click on the usb root hub, then click on properties,click on power management tab and uncheck the "allow the computer to turn off this device to save power"

    5. Run USB troubleshooter
