No, the "stopped" is ok.
Do you see this:
Code:

What does "lsusb -v" on your Linux box say? (Just the interesting stuff, please.)
Or what does dmesg say when you plug it in?
Edit: Sorry you got me a bit confused. When you were talking about what you saw in old logs I thought you meant what you were seeing then.
That Mass Storage you were seeing was probably something related to charging mode where it switches to UMS "Linux-Stor" without any mounted volumes.
VID/PID and descriptors are what we need.
