I’ve continued to test rockbox for a week or so now. 

rockbox stable release (version 3.12)  seems to be flaky when it comes to interfacing with a PC.   I noticed it first on Windows 7 the driver had difficulty loading.  I did a google search and found that someone else also reported this issues.  I also experienced it with Windows Vista.  The driver didn’t load at all and I didn’t have time to research if there is a work around or not.  Tonight I tried to interface it with the same PC I installed the rockbox with.  It’s currently running Linux Lite 2.8 64 bit.  It’s based on Ubuntu 14.04.  The device didn’t want to mount.  Froze up several times, and after reconnecting and holding down the power button etc. several times I managed to get it to mount.  I wonder if the development version does any better?
