The H1 2/0 firmware update introduced a new feature. When you plug the H1 into USB port you get an alternating display of 2 choices: Audio (H1 as USB microphone) or Read SD card). When connected to a USB 2 port both work fine. When connected to a USB 3 port only the audio option completes. On the Read SD Card option the drivers load but it does not complete.
Somewhere I did not make my point clear - sorry about that. I was interested in trying the H1 as a USB mike not transferring data. I too always use a card reader.
