While installing the new firmware I ran into serious problem.
I always use MSC mode and my PC doesn’t have the needed WMP version for using MTP mode. I upgraded the firmware several times in the past always remembering to change the USB setup to MSC mode (It changes to Auto when you upgrade the firmware)
Yesterday after installing the new firmware I used the clip for a while and connected it to charge over night forgetting to change the USB setup to MSC. In the morning I found that the battery is completely drained. The clip didn’t charge even though it was connected to the USB port and showed on the clip screen that it was connected.
This is a real deadlock, I was not able to change the setting of the USB to MSC since the battery was dead and I was not able to charge since I was in Auto mode.
Finally I have noticed that it does charge for a very short while and only then it stops charging. So I connected and disconnected the clip for a several times giving it enough juice to be able to switch the USB mode to MSC and then everything went fine.
I think that the clip should always charge when connected to a USB port regardless of the USB mode it is setup to, and regardless of the SW on the PC.
