Version of Windows?
Are the US3.0 ports completely dead or will a USB2 device work?
Do the 4 front USB3.0 ports work? And what about the one rear USB3.1 port (first on the left)?
What drivers did you uninstall? And did Windows automatically reinstall them?
Is anything marked in Device Manager as "unknown" or with an X or ! ?
You could try reinstalling the chipset driver
You could also try clearing BIOS:

Hi, Ron Sorry for the Delay I have attached a screenshot of the device manager and the Answers
The version of Windows? Windows 10
Are the US3.0 ports completely dead or will a USB2 device work? just Confirmed that only the 2 left USB 3.0 and 2.0 don't work they have Power but no communication with devices
the 4 front USB3.0 ports work? And what about the one rear USB3.1 port (first on the left)? All front 4 USB 3.0 Ports Work but the rear left USB 3.0 and 2.0 Don't work
What drivers did you uninstall? And did Windows automatically reinstall them? Uninstalled USB 3.0 and yes Windows automatically reinstall them
Is anything marked in Device Manager as "unknown" or with an X or ! ? NO
You could try reinstalling the chipset driver YES
@sierra1010 We cannot view you image until it is approved. When you stated that in the rear of the PC the two left USB 3.0 ports don't work do you mean the USB 3.1 port and the USB 3.1 Type-C port don't work and the three USB 3.0 ports do work? I just want to make sure you realize there are USB 3.1 ports.
Perhaps it will be clearer to me when I can see your pictures. There has been an issue with the USB ports on the XPS 8910 that has been discussed in this forum. In some cases the USB 2.0 ports have failed and Dell has replaced the motherboards if they were under warranty. I have seen this problem on my XPS 8910, but my ports did not fail completely just stopped working intermittently. To ensure that the ports do not fail, I use a powered USB hub on the USB 2.0 port and connect my keyboard and mouse to the hub.
Thank you for the help the photos should be on the forums, I also tested powered USB HUB on the one of the USB that does not communicate, and it does not help
Perhaps I was not clear, I did not want to imply that a powered hub would make failed port work again, only that a powered hub would protect a port from failing. There was some speculation in this forum that the ports, especially the USB 2.0 ports, failed because they were overstressed from supplying power to USB devices. Normally the USB ports should be able to handle this, but in the case of the XPS 8910 it was a problem.
Here are some of the thread related to this issue (some of the older threads are no longer available):
Microsoft has various security and feature update bugs, which broke audio, USB devices/core inputs including cameras, keyboards, and mice. ASMEDIA has security issue so microsoft updates DELIBERATELY DISABLE These ports. This update fixes security vulnerabilities in the ASMedia xHCI (USB3) firmware.
What you have to do is remove the ASMEDIA USB3 drivers INTEL Chipset Drivers and REINSTALL the Chipset then OEM drivers.

ASMedia drivers only affect the USB 3.1 ports. If Microsoft updates disables USB ports you would expect that it would disable all the ports not just some of them, OP said only the rear left USB 3.0 and 2.0 port don't work and that all front USB 3.0 ports work.
