Ok, thanks.
If the device information is missing completely on the udisks2 bus, the sysfs
representation of the stick might lack some properties that udisks2 needs for
proper indentification.
Please provide the output of:

udevadm info -a /sys/$SYSFS_PATH

where $SYSFS_PATH is the path to the usb device below /sys.
For example in comment#19 you showed your devices sysfs path as: 

dimesio@linux-prda:~> udevadm info /dev/sdd
P:
/devices/pci0000:00/0000:00:16.2/usb5/5-3/5-3:1.0/host10/target10:0:0/10:0:0:0/block/sdd

So the command would be:

udevadm info -a
/sys/devices/pci0000:00/0000:00:16.2/usb5/5-3/5-3:1.0/host10/target10:0:0/10:0:0:0/block/sdd
