While turned off, when I connect my Sansa e280R to any USB dock (Griffin, Timex, inMotion), the unit turns on, shows the Sansa logo, the blue wheel lights up and stays on (I have the wheel light configured in Rockbox to shut off) and then freezes on the Rockbox screen. The backlight timer still works while this is happening. If I then disconnect it from the USB dock, the wheel light finally shuts off, Rockbox resumes, and then I can reconnect to the USB dock without any problems. This is really annoying to deal with when I want to use it in my car with the dock.
I am running version r16523-080305 of Rockbox. The last version of Rockbox that I had installed back on February 26th did not manifest this problem.
Is this a known bug?
