    USB: another unusual_devs entry for another bad Argosy storage device · e2673b28
    Nguyen Anh Quynh authored
    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):
    ....

    [  138.921923] sd 7:0:0:0: [sdb] Add. Sense: No additional sense information
    ....
    
    After the fix, dmesg returns below information:
