I've a USB Adapter plugged into my PC but I cannot recall what it is for.

It is not for bluetooth or wireless

And unlikely is for wireless headset

So, is there a way to check what it is for?

[WhatDoYouThink?]

could be for mouse or keyboard

Just take out and see anything not workable.

Print screen your bluetooth device and USB device first under device manager.

Then plug in the unknown USB adapter.
See it will appear at bluetooth device column  or USB column.

Cheapo mouse normally it will show as HID compliant driver under mouse column.

Sometimes, you can go to update windows  select optional driver. Your gadget driver can be found there.

Never update optional audio driver if you are not sure what sound chip you are using.
If the computer no sound dont cry... sometimes not easy to troubleshoot.

The rest the optional drivers for other gadgets still can be easily removed
