dmesg log (from boot)
I have a specific USB harddisk that keeps getting resets and never appears as a
device on the system. It used to work just fine, but as I did not use it for
anything important when it stopped working, I did not do the proper paperwork
back then. Unfortunately this means I cannot tell you when it last worked; I
guess it has been over a year and perhaps even 2 years.
I have used USB pens after the harddisk stopped, so I have a feeling it is
specific to the device. It is a "Packard Bell Store & Save" (~750 GB) and the
model number is "HD D2 U2". It has an external power and has a little "USB
2.0" next to its USB plug.
I have tried in once in a Windows a while back, but without any luck. Though
I could not tell if this was because the disk was broken or because Windows had
no clue to handling the underlying file system[1].
I am attaching my dmesg log (fresh boot and with the USB being turned on when
the boot has been completed). I will follow up with a lsusb -v output. The
machine uses a 64bit kernel with 32bit user land.
This is a forward of the Debian bug #639462[2]. I have used the Debian kernel
for my testing and (to my knowledge) it contains the "EHCI: fix direction
handling for interrupt data toggles" commit (see [2] comment #22)

[1] It is encrypted with cryptsetup luksOpen/luksClose and has (as I recall) an
xfs layer beneath that.
