Although its possible, I don't really know if the USB device could get
confused under that circumstance. The reason (or at least the main reason)
for the "Safely Remove Hardware" is, as you stated, to make sure any
outstanding write caches have been saved before removing the device. As far
as I know the biggest problem with skipping "Safely Remove Hardware" is that
you could have data loss, which is never good. ;)

Subject: -=PCTechTalk=- Hibernation and USB drives
I was doing some reading in Hibernation help files the other day. Once a
computer is placed into Hibernation any attached USB devices, such as thumb
drives and hard drives should be left attached until the system is awakened
and "Safely Remove Hardware" has been accomplished. I ass u me the same
applies for Sleep (and maybe standby) and in Vista Hybrid Hibernation.
It did not explain why, but as I was just re-reading a post by Gman about
USB drives and their cache, it dawned on me the cache is the reason. The
system state is saved as it is. The cache may or may not be empty at the
time If it isn't and you remove the device while in hibernation, the system
will be very confused when you awaken it. Confused systems do strange
things that almost always confuse the operator. So, before you hibernate or
take a nap, safely remove your USB devices. This includes built in card
readers, cameras, mp3 players etc.
