My IQ shows up as an IQ. Do you by any chance have your IQ rooted? When I tried to root mine (I didn't get very far) and had USB debug connected, Calibre acted kinda weird with it--pretty much what you're saying. It showed as a Pandigital Novel, it didn't show any books at all either on the device or on the SD card, it didn't show the books in the library as being on the device, it pretty much didn't work at all. As soon as I gave up on rooting and disconnected the USB debug, it went back to normal. It is now seen as an IQ, the library shows which books are where, I can send books to my little heart's delight.

I know Kovid added the IQ on the last upgrade, and he even switched the internal sd card and the external one so we can use the external card to store books instead of being limited to the smaller internal card.
