I've installed KSM, and it went smoothly; I also installed KOReader, is it meant to just be a file manager?

I've installed the autoshelf mod, but I've yet to make it work.

I think that both of these new features are stifled by my sdcard now not working after installing KSM. It works when put into an sdcard reader, but when put into the kobo it says 'you have an sdcard' (or whatever it says, I can't remember), and then doesn't import books. Also, in KOReader /mnt/sd looks like:
/Volumes/EFI
└── koboExtStorage
.......├── dict
.......├── images-cache
.......└── kepub
and is called 'EFI' when the kobo is in usb mode, and this will come up regardless if there is an sdcard in the kobo or not.
