Hi,
Thank you for posting this question on Microsoft Community Forums.
Under what driver category will I find the drivers for a 'Universal Serial Bus (USB) Controller'? Dell Optiplex GX270. Download the latest drivers for your Dell OptiPlex 9020 to keep your Computer. Intel(R) 8 Series/C220 Series USB Enhanced Host Controller #1 - 8C26.
I see that the USB devices aren’t recognized with the error code 28.

Let us work together and resolve this issue.
However, we need more information on this issue. Please answer the following questions.
1.Did you make any changes to the computer prior to this issue?
2.What troubleshooting steps have you tried?
This code means the drivers for the USB devices were not installed completely.
Here’s what you can try:
Method 1: You may try to run the Fixit.
Hardware devices are not working or are not detected in Windows
Method 2: Run the hardware troubleshooter and check what happens.

Method 3:
As all the hardware devices have drivers associated similarly USB devices also have it. Sometimes proper drivers do not get detected after the initial installation so reinstallation of the drivers helps resolve the issues.
You may check after uninstalling and reinstalling the USB drivers if you are able to connect. You may disconnect all USB devices and then perform the following steps:
1. Click Start, and then click Control Panel.
2. Click System and Maintenance, click System, and then click Device Manager.
Note: If Control Panel is in Classic View, double-click System, and then click Device Manager.
If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.
3. In Device Manager, double click to expand 'Universal Serial Bus controllers', right click on the Host Controller, click 'Uninstall' and click 'OK'.
Check if at all there is an exclamation mark along the driver, it suggests issues with the driver installed.
4. Repeat the step 2 to uninstall all items under 'Universal Serial Bus controllers'.
Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.
If you still face the same issue then you may check for the updated USB device drivers using windows update. Refer to the below link for assistance–
If the issue sill persists I would request you to check for chipset driver updates which you can get at the manufacturer website. The chipset drivers normally incorporate USB controller drivers as well.
Please get back to us with the results.
If you have any further questions about Windows, write to us anytime.
Dell not offering Windows 10 drivers for Optiplex 990.
Bus Controller
I am furious that these systems, which are under 5 years old, are not being supported for a major Microsoft release.
It's not just that I can't find network drivers on Dell's website, but that I can't find NIC drivers anywhere that work with the onboard LAN port. My only option appears to be to scrap machines or use an expansion card in the chassis; something I'm reluctant to do.
