What USB devices are connected to your computer? Keyboard? Mouse? Webcam? Printer? Memory-stick? Scanner? iPhone/iPad charging cable? Digital camera?
Do each of those devices work, when connected to a DIFFERENT computer?

The devices plugged into the usb are Keyboard, Mouse, Printer and Scanner and they all work. The problem is when I plug something new in. It does not matter what I plug in, I get the same messages. It just won't accept anything new no matter what port I use.

Your motherboard can only supply a limited amount of power to all your devices.
Experiment: disconnect the printer & the scanner, and then connect that "something new" device, to see if it will work.

I plugged a storage thumb drive into the USB. I can open the files on it but I still get the error message "Unknown USB Device (Device Descriptor Request Failed)". I am trying to plug a Bluetooth dongle but it will not recognize it.

Normally, that implies that Windows has read the "descriptor" information from the device, and used that information to load the correct device-driver.
- click with the right-side mouse-button on the Windows 10 "start" button
- click on "Device Manager"
- expand that "USB" branch of the "tree"
- is your "storage thumb drive" listed as a correctly-installed device?

Is that dongle correctly installed, when you connect it to a different computer?
