I recently downgraded my HP 15-r209ni Notebook from Windows 8 to Windows 7. Only Windows 8 drivers are listed under the support page, but they all seemed to install and work just fine. The only problem is that my USB ports don't work after Windows loads up. There aren't any drivers under the support page and Windows Update can't find them, nor can several driver update programs - It's just listed as an unknown Universal Serial Bus (USB) Controller under the Device Manager.
Any idea where I might be able to get those drivers?

Hi there @Mosimanegape,
Thank you for visiting the HP Support Forums and Welcome. It is a great site for information and questions. I have looked into your issue about needing HP Notebook - 15-r209ni Windows 7 USB drivers.
As this system came with Windows 8, downgrading could be challenging. Some of the drivers are not available for Windows 7 systems and you would be missing some of the special features. Here is a link for you to understand your downgrade rights.
You had said "There aren't any drivers under the support page and Windows Update can't find them, nor can several driver update programs".
Which update programs have you used?
How many devices are you trying to connect?
What are you trying to connect via USB?
Did you happen to try using the HP Support Assistant?
Here is a link to the HP Support Assistant if you have not tried it yet. Just download and run the application and it will help with the software and drivers on your system that need updating. It should pull in the most compatible driver for you on Windows 7.
Below are other troubleshooting steps that may help also. If the USB device does not display in Device Manager, then there might be a power requirement issue. Disconnect the device and perform the following steps until the device is detected:
- Restart the Notebook
Connect the device and wait 5 seconds.
If the device does not show up, try connecting to a different USB port.
If the USB device displays in Device Manager after connecting the cable to a different port, then uninstall and reinstall the USB device software driver.
If the device is not recognized in any port, disconnect it and go to the next step.
- Open Device Manager.
Double-click Universal Serial Bus Controllers,
Double-click a USB Root Hub,
Click the Power tab,
Click Power Properties (if it is shown).
Devices that are attached to the hub are shown, as well as the power that they require. If the total displayed power is over 500 mA, remove the devices and use a powered hub.
Continue looking at the power properties of each USB hub. If the total Power Required exceeds the Total power available for the hub, then remove a device on that hub to lower the Power Required number.
Connect the device and wait 5 seconds. If the device is not recognized, disconnect it and go to the next step.
Please Note; remove high-speed USB cables that are over 3 m (9.8 ft) in length and use high-speed cables that are shorter than 3 m.
You could also try to use the Microsoft Fix it tool. Here is the link for the Microsoft Fix it Solution Center.
