Hello and welcome to the forum.
This first thing you'll need to do is identify that actual device.
Open device manager and right click the problem device and choose properties.
Select the details tab, use the drop down to change from Device description to Hardware Ids
Right click the contents of the "Value" box and select all, right click it again and copy.
Open notepad or similar and paste it, print it.
Open a search engine and type in the top value and you should be able to determine the manufacturer and model number and from there you should be able to locate a driver.
How you get it to your PC where you need it, is another matter. It'll likely involve using another computer to download it and then burn it to a DVD / CD, or USB thumb drive, so ......
Maybe get a friend, family member, neighbor, associate, complete stranger, sworn enemy.... involved.
