I found that I had all device_file options for sda, sdb and sdc in ~/.config/udiskie/config.yml set to "ignore: true". sdd was ok, and that was where removeable drives ended up until I removed hard drives sdb and sdc. Removeable drives then went to sdb, which was ignored.
udiskie's "--verbose" mode helped solve this. You can close this bug now. Thanks, .....Ron -- Ron Murray <r...@rjmx.net> PGP Fingerprint: 4D99 70E3 2317 334B 141E 7B63 12F7 E865 B5E2 E761
