Title:
  UDisks.Device.DriveDetach() permanently powers down card *reader*

Status in “udisks” package in Ubuntu:
  Confirmed

Bug description:
  The UDisks.Device.DriveDetach() DBus method will permanently power-
  down a card *reader*... if you remove the card and insert it again (or
  insert a different card), nothing happens.  The only way to get things
  working again is to unplug the card *reader* and then plug the card
  *reader* back in again.

  DriveDetach() is what gets called (apparently) when you right click on
  the Launcher icon for a card and "Safely remove"... same effect, and
  you have to unplug/replug the card *reader* to get things working
  again.

  This is fundamentally a problem in UDisks, but I feel "Eject" vs
  "Safely remove" is horrible, horrible UX... this is just forcing the
  user deal with the fact that UDisks and/or the kernel isn't smart
  enough to really understand the hardware details.  Considering how
  broken things are, I strongly feel than Unity should only present the
  "Eject" option.  "Safe remove", in my experience thus far, will never
  do something useful and intuitive for the user.  Plus it's just bad
  branding... Ubuntu lets you perform an "Unsafe remove"?  Why should I
  have to manually pick a "Safe remove"?  Why would I ever want anything
  else?

  For what it's worth, this kind of stuff makes it very difficult to
  present Ubuntu as a viable platform for pro video users.  Card readers
  are standard equipment in pro video (and photo) workflows, and
  currently things are embarrassingly broken.
