Windows decided to randomly install an updated driver today for my device (logitech F540) and replace it with a "UAC3556B" driver. Of course...it doesn't work. now windows is turning the default audio device volume to 100%. trying to turn it down results in it just slowly go back up again. muting the device results in it being unmuted. simply disabling the UAC3556B device in the device manager still results in this happening. i have to physically unplug the device from the system to regain volume control.
how do I get rid of this driver and go back to the proper one? logitech website does not list any downloads/drivers for this device so I can't just reinstall another driver. they have instead relying on windows to supply drivers.

uninstall the driver and download a new driver.
I would suspect it was simply a driver issue.
Also you could consider installing Logitec Gaming Software. It will help you maintain your Logitec hardware

Can't you go into the device manager or System Restore and do a Driver Rollback? Windows is supposed to make changes every time you install something big like this , and yes it's a big deal.
I did some changes to see where system restore is in Windows 10 and its a bit of a you know what to find it.

This may actually be a hardware problem rather than a driver problem. Have you tried it on another operating system? That would show one way or the other.
If the firmware is damaged or unreadable, the UAC3556 chip reverts to a generic USB audio device configuration.
