It is but HAL can't read type and other attributes of your memory stick. Wat 
is the content 
of /sys/devices/pci0000:00/0000:00:02.2/usb3/3-5/3-5:1.0/host6/target6:0:0/6:0:0:0? 
It is possible that device needs more time to initialize, so adding 
WAIT_FOR_SYSFS somewhere may help; current udev should have something like

{pts/1}% cat /etc/udev/rules.d/05-udev-early.rules
# sysfs is populated after the event is sent
ACTION=="add", SUBSYSTEM=="scsi", WAIT_FOR_SYSFS="ioerr_cnt"

do you have similar?
