Hello,
Greetings,
I have dell xps L501x i7, issue i am facing is usb 3.0 is not at all detecting pendrives, i have tried several of them but the other side port are completely working fine. But when i reboot it work for a moment then it get automatically disconnected.
I am not able to figure out what is happening.
 
Try this...

1. Go to "Control Panel" and then "Device Manager".
2. Expand the "Universal Serial Bus controllers" section.
3. Double-click on the "USB Root Hub device".
4. Now click the "Power Management" tab.
5. Uncheck the "Allow the computer to turn off this device to save power" option.
6. Click the "OK" button.

NOTE: If there is more than one "USB Root Hub device" listed, Then you will have to repeat this steps for each one of them.

7. Restart the computer and all the ports should work now.

Should that not work, then you may want to try this... https://support.microsoft.com/en-us/help/17614/automatically-diagnose-and-fix-windows-usb-problems
