Quite a few people have just gone ahead and wired it up for USB power. The theoretical issue is that the Meggy Jr can draw more power than the port is rated for, with the theoretical consequence that it could destroy the USB port on the computer. However, most USB ports are power limited, and we’ve never heard of any actual ill effects from doing this. On the other hand, we can’t guarantee that it’s safe in all situations.
