Being a layman, I have no idea about what protocol precisely HTC One uses internally, and tbh I don't care since it works exactly like a normal USB device with both of my PCs.
Good for you. However, it's not as easy if you're not running Windows 7 or Windows 8 because it doesn't support UMS, it supports MTP, so in this case it neither walks or barks like a dog.
Next time, if somebody posts "Since this phone doesn't function in USB MAss Storage mode", you'll know it "doesn't function in USB Mass Storage mode" and you'll have no need to incorrectly correct them.
