USB Data Transfer?

I'm running into serious problems trying to transfer files to my phone via USB, in particular, Win10 is not recognizing the phone in USB transfer mode as a drive, it recognizes it as a device, but I get the impression I am going to need some driver or something to get it to play nicely, advice?

Yeah, I've already done all that prior to my posting, and I still cannot get it to show up as a device under My Computer, though the device shows up in Device Manager.
