Hello everyone,

My PC runs a gate software named DoorKing. I have a USB to Serial cable that talks to the box. It has worked for well over a year now. Sometime in the last week or so they stopped talking.

What I have done: checked usb port with other plug and play devices and YES the port is working fine. I have also tried other ports. Same problem.

the drives are: serenum.sys and SVK9PL64.sys

It won't allow me to roll back to previous drivers and updates are working. In device manager it shows me that there is a problem everytime I plug in this particular usb device.

Any help would be great. This is for ministorage facility and none of my gate cards are updating for my renters so it is becoming a nightmare!!!

    Hello, I'm Louie, and I'm happy to help you today. Hope you're doing well and safe there. I'm sorry that you're having trouble with your USB ports.

    I would suggest you to try the methods provided below:

    Method 1 - Check Power Management Settings

    1. Right-click on the Start menu button and select Device Manager.
    2. Expand Universal Serial Bus controllers
    3. Look for the first USB Root Hub. In some computers, it could be just one. Right-click on it and select Properties.
    4. Go to Power Management tab. Here, unmark the box beside Allow the computer to turn off this device to save power. Click on OK.
    5. Repeat Step 3 and Step 4 for other USB Root Hub devices under Universal Serial Bus controllers.

    Method 2 - Check Power Supply

    1. Unplug your laptop’s power supply, along with the charger plug.
    2. Now, restart the laptop.
    3. Reconnect the USB device to the USB port of your laptop.
    4. Plug charger and power supply back on your laptop.

    Method 3 - Uninstall Drivers

    After performing the restart, the Windows will recognize USB Root Hubs as new device and will install its drivers automatically.

    6. Restart your computer.

    Method 6 - Disable USB Selective Suspend Setting
