For a while, I haven't been able to connect my Kindle Paperwhite 2 to my computer. Or any computer. This is frustrating because I have files I want to read on it. I can't transfer these over wifi because they're too large. And I can't transfer with USB because it's not showing up.
I've tried lots of things. Resetting my computer (which runs Windows 10) and Kindle multiple times, including a hard reset. I've changed selective suspend settings. I've uninstalled and reinstalled the USB controllers. I've tried lots of different cords. I've tried connecting my Kindle using those lots of different cords to different computers. Some of those cords were working with my Kindle just a month ago.
No matter what I've done, it still won't show up in the files

Any suggestions?
