For reasons external to this issue, I needed to re-installed 9.04 on my system....don't ask. Starting with a fresh 9.04 and applying only the karmic packages as outlined by Amr in an earlier post, my system now recognizes both of my Sansa players (one rockbox and one with original firmware). My earlier issues must have been related to changes I made during various failed attempts to fix the problem. Thanks!
