My Nano suddenly started acting up. The computer won't recognize it and keeps giving a mass storage device malfunction message. We've tried different cables and computers with the same results. You can take the chip out and download the flights fine, the computer just won't recognize the Nano. Anyone have any experience with this ? So far Im not getting much back from LX..
thanks

Are you running the latest Nano firmware (version 2.30)?
Have you upgraded it lately?
Have you tried downloading it with NanoConfig?
