E-Reader not showing on Digital Editions

[NicolineL]

I recently received a Pocketbook E-reader, which I tried to load borrowed books from my library onto. 

After realizing I needed to authorize my E-reader through Digital Editions to read the books (since they are ACSM files), I tried plugging the E-reader into my computer, where it was supposed to pop up in the left side of the ADE app. It didn't, and now I can't download any DRM-protected books.

Can anyone help me with why it isn't showing?
