Yes, my computer detects it and it also shows up in calibre.
What's on the screen is my book library, listed by title. It's stuck on the letter A ... at least it's alright, it's nothing too embarrassing haha, Adventures of Huck Finn, Alice in Wonderland, etc
I guess it's been frozen for a good hour now.... maybe a little more.
Edit: it froze after I browsed the library, I wanted to open one of my new books, but I never got the chance. I hadn't tried to open anything yet. But yes I had just added 2 pdf books. I got a loading screen before browsing the book list and it seemed alright.
