I got it fixed this morning. First, storage has 9GB free so that's not a problem. Second, yes, I use USB connection just fine, all working there.
So, what I found is that I had 455 files in 17 subfolders. Also, I had mistakenly extracted all 455 files and 17 subfolders to a sub-subfolder! So there were 455 songs in the folder I was importing and the same 455 songs in a subfolder with the same names but different dates. Once I removed that sub-subfolder, and also deleted the collection from the tablet to start afresh, the import worked. As a software engineer, I can't quite figure out why the import would care about this; it seems it would just overwrite the existing duplicate file. But anyway, something about having the sub-subfolder with the same files caused a problem.
