Odd, I don't see any delay starting Koreader, in fact, with the "Start in last opened file" option I am reading in less than a second, from making the selection in Start Menu. I do think that the things I use respond snappier since using the Kobo Start Menu. I also have my library in a .hidden folder on the external uSD card.
I can't comment on the effects with USB enabled, but don't you see both uSD cards on your PC? While it could be an issue when trying to monitor the device's functioning, just for use of the storage functions you don't need the device's OS accessing the cards, while using the USB connection.
Luck;
Ken
