I have another Argosy USB storage device, which has the same problem
with the Argosy USB storage device already fixed in 2.6.27.7. But this
device has another product ID (840:84), so this patch adds a new entry
into unusual_devs to fix the mount problem.
I enclose here two patches: one against 2.6.27.8, and another against
the latest linus-git tree.
The information about the Argosy device is like below:

Before the patch, dmesg returns a lot of information like below (my
dmesg is overflown):

After the fix, dmesg returns below information:
