What I normally do to start is open File Explorer and look at the network section. If you know the name of the device, type the following in the search box. Hopefully, it will allow you to enter a password which will put that info in the credentials section of Win 10.
My NAS is on the actual network so the USB connection may require you going to the Linksys router first, maybe the admin page to set up the connection. So you might try \\DeviceName for the router (or its IP address) and see where that goes.
