I have encountered the same trouble with 08ec:0015 M-Systems Flash Disk Pioneers Kingston DataTraveler ELITE udisk --monitor output lots of "changed: /org/freedesktop/UDisks/devices/sdb" before "added: /org/freedesktop/UDisks/devices/sdb1". I tried to change sdb1 partition type from 6 (fat16) to b (fat32) because I'm not sure of the filesystem but that doesn't change anything about udisks-daemon CPU usage and delay before be able to mount the partition.
