Since I resolved the problem, I wanted to leave the answer for others.
I tried reinstalling everything to no benefit. The DS kept coming up as CDMCM-210 and kept disallowing direct DSD playback. I started searching google for any instance of CDMCM-210 and found a thread in the DS Jr product area that seemed to reflect the exact same situation. The last thing mentioned in it was the owner should check volume leveling and crossfeed should equal zero. Since I know that I have one channel set about 2 db higher than the other due to come volume inconsistency in the rest of my system, I set both to the same volume and rebooted everything. That did it. The device came up as “PS Audio DirectStream DAC” and DSD played directly. It seemed to hold onto that setting after I changed it back to be 2 db higher in my right channel.
