2.6.27-stable review patch. If anyone has any objections, please let us know. ------------------ From: Nguyen Anh Quynh commit e2673b28911a43257265523e3672861be6e44093 upstream. 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: #lsusb -v -d 840:84 Bus 005 Device 005: ID 0840:0084 Argosy Research, Inc.
