OK, so I’ve had two 2GB clips for some time, and they work well.
I got a new 4GB silver Clip and I plug it in.
The clip connects for like 5 seconds says “Connected” and then it disconnects. It repeats the cycle endlessly. I can’t update firmware, because it won’t stay connected.
I’m pretty sure the USB cord is fine, since I connect the other clips to the same USB cord. I’ve tried forcing MSC mode, no help. I’ve installed WMP 11 and nothing.
