I connect my DI via USB and select Mount(SD card is in there), but nothing shows up on my desktop. Talked to Verizon who turned me to HTC. The only advice the woman offered was to select USB debugging under Settings>Applications>Development. But this changed nothing. Bluetooth between Mac and DI is not working for me either. Hopefully things will change but as of now they are not looking good. How am I supposed to get my music on this thing!? Anyone with any insight?
