Getting back to this...
I have several mount points under /mnt, which is where I was trying to mount.
As I was having trouble, I made a fresh mount point at /newmnt

Originally I saw no allow prompt on the phone.
I thought the I/O error meant it didn't work, so issued umount but left it plugged in.
A few minutes later reopened the phone and the allow prompt was there.
Hit allow, then tried again and it worked.

I'm thinking it's the procedure, not the mount point, which made the difference.
