udisksctl dump

When I attach/automount my USB pen drive, I am prompted to enter root's password. Other USB hardware, PTP Camera, MP3 player automount as "user" fine.
I have tried setting Selinux to permissive (nothing related in the logs)

Fedora 18
disks2-2.1.0-1.fc18.x86_64 (rebuilt from F19 to the current version)
gvfs-1.14.2-3.fc18.x86_64
libatasmart-0.19-3.fc18.x86_64

This I guess is the reason my pen drive does not show up in KDE SC device notifier.

Apparently device-mapper-multipath thinks that your USB stick is a multipath device and tries to be "helpful" (probably because there are two devices: the real usb mass storage device and a fake cd-rom device with windows drivers).

Sorry but there is nothing udisks can do about this. You should file a bug against device-mapper-multipath in Fedora telling them to fix their software. For now you can probably remove the symptom by simply uninstalling the device-mapper-multipath RPM. But please do report the problem. Closing.

Thanks for the info and pointing me in the right direction. device-mapper-multipath or a config file was the problem and where possibly corrupt maybe after a system upgrade. Repaired and everything is working fine now.
