I have the same issue: I can't upload more than 1 book a time. I used Adobe Digital Editions only (as one of the books was DRM protected). I uploaded 2 ePubs - 1 DRMed, 1 not protected. After ejecting USB device Kobo went to processing content. It stuck on 9 % for a good couple of minutes. I turned it off, turned it back on - the books didn't appear in the library. Connected USB again, the files were on the device but Kobo didn't show them in library. I removed both files, uploaded just one book - succeeded - processing content took less than a minute, book appeared in the Library.Uuploaded the other book - it worked as well.
Concluding - Kobo Touch has a hard time processing more than 1 book uploaded a time. It's not Calibre related.
