Subject: [Bug 89511] USB-storage mount error
https://bugzilla.kernel.org/show_bug.cgi?id=89511
--- Comment #3 from Jun Itou <itou_jun@...oseek.jp> ---
Because it occurs in Debian7.7 and Fedora20, I think this symptom to be a
problem of kernel.
I confirm that I do the same operation in the following devices and reappear.
I-O DATA HDZ-UE2.0TS
I-O DATA HDZ-UE1.0TS
I-O DATA HDZ-UE1.0TS
I-O DATA HDW-UE
I was as follows in Fedora20.
