Bug description:
  --Impact--
  Newer dell bluetooth adapters don't work after flipping on/off the hardware switch or after S3

  --Addressing--
  The development branch for karmic hasn't been opened yet, but this patch will be forward-ported when it is.  The patch is to a file in debian/ so it doesn't need to go upstream.

  --Test Case--
  1) Find a machine with one of the following devices on the USB bus:
  	Vendor ID / Product ID / Model
  	0x413c / 0x8154 / Dell BT 410
  	0x413c / 0x8158 / Dell BT 370
  	0x413c / 0x8162 / Dell BT 365
  2) Attempt to suspend to RAM.  When resuming, observe that there is no bluetooth icon in the tray.
  3) Upgrade to the proposed package
  4) If the bluetooth icon isn't in the tray to start (depending on if the bluetooth service got restarted during the package upgrade) run
  $ sudo hid2hci --tohci
  to get it in the right state.
  5) Attempt to suspend to RAM.  When resuming, observe that there is now a bluetooth icon still in the tray.

  --Regression Potential--
  None.  This rule is only used on Dell BT adapters, and the existing rule does not work w/ the udev in Jaunty.
