I have a Lenovo laptop running Windows 10. There are 3 total USB ports (1 on the left and 2 on the right). For some reason the 2 ports on the right suddenly stopped working. They won't recognize any device plugged in. I checked in Device Manager and it does not show any errors with the USB configuration. I even opened up the laptop case to look inside to see if maybe something got disconnected, but everything looks fine with the hardware itself. The USB port on the left still works fine.
for stuff like this i usually boot up a live-usb to diagnose whether the physical hardware is mashed up or if the windows software configuration got mashed up.
I confirmed it's a hardware issue. I plugged in a USB flash drive that has a red light that comes on when plugged in. In the left port the light comes on, but in the right ports it doesn't. So something must have got fried. I bought a USB hub on Amazon for 10 bucks so I'll use that and plug it into the working port.
I have about 5 Lenovo Laptops. Sometimes a mischievous hacker will disable your usb port. Go to Device Manager and disable then re-install all of your usb port drivers. Then you might find the pertinent one to blame.

Yeah, I tried that but it still did not work. It seems that there is not even power being supplied to the ports.

Did you actually do what Stanley suggested?
With this type of issues, you have to determine if it is a hw issue or Windows issue. What you stated to having done thus far, didn't quite clarify where the culprit is. To make sure, create a bootable USB drive. You can download a "Live" iso of a Linux distro even an using ISO burner type utility, create your bootable USB drive, then boot to it. Make sure the bootable drive is the only thing plugged and it is plugged in on the right (not working) side.
If I were you, I would run included hardware diagnostics that should be accessible during bootup.
If such diagnostic utility was installed and also checked USB ports. IF so, have a USB drive with data plugged in one of the bad ports and run the test.
Also I'd go into BIOS settings and make sure all related settings are enabled.
I have seen cases with various different make/model laptops where Windows do not detect/charge/show any and all devices plugged into a certain USB port, causing you to think the port is bad. Re-imaged the laptop and the presumably bad port started working.
Instead of imaging, try uninstalling it in Device Manager first, check the box for uninstalling the device drivers as well but make sure to have the latest drivers already downloaded first!
After uninstall/removal, reboot your laptop and install the latest (USB3) drivers.
I'd also install the latest chipset drivers as well.
If the ports look dirty with dirt/dust particles, you can use compressed air can to blow it clean.
Additionally, try cleaning the connection surfaces inside the ports using a Q-tip dipped in little rubbing alcohol.

Well like I said, I have a USB flash drive. When I plug it into the "good" USB port the red light on the flash drive comes on. When I plug it into the "bad" ports the light does not come on, so obviously there is no power being sent to those 2 ports and I'm not going to be able to boot from it.

good diagnosis. i assume they are bruk up.
the only other thing is maybe they are thunderbolt ports and the bios shuts them off to conserve battery (so they seem dead before the os boots).
something like that was for my blu-tooth radio. i thought it was broken until i went into the bios and can turn it on and off.
