@Pat: One important thing: Don't use hciconfig up <dev> anymore. Even if
its still there and works to some degree that will only initialize the
controller partly as its using an old kernel API. Use bluetoothctl only
to power on/off bluetooth:

$ bluetoothctl
[bluetooth]# power on
Changing power on succeeded

As in this case you don't see an LE device this comes from the fact that
we power on bluetooth via hciconfig.

Title:
  Can't connect Logitech Living Room Keyboard [LE]

Status in Canonical System Image:
  New
Status in bluez package in Ubuntu:
  Confirmed
Status in ubuntu-system-settings package in Ubuntu:
  Confirmed

Bug description:
  Cannot connect a Logitech Illuminated Living Room keyboard to a device
  running bluez5.  There are two versions of the keyboard, a unifying
  receiver version, and a Bluetooth version.  The latter has a BT symbol
  on the 'del' key.  To put the BT version in pairing mode, power on the
  keyboard, then briefly hold the FN and 'del' key together and release.
  A green LED at the top right of the keyboard should start flashing
  quickly.

  Once in pairing mode, the device will become visible on desktop using
  the BT settings UI, however it's *never* shown in the UI on a device
  running the latest Touch ( OTA9.1+ ).  Note, this includes devices
  running a silo version of bluez 5.37, including both arale and
  krillin.  On both devices, the keyboard *is* viewable using
  bluetoothctl.

  It should be noted that LE keyboard support on touch should be a
  considered a missing feature.

  Here's the reported attributes of the device from my macair running
  15.10 + bluez 5.37:

  From bluetoothctl on both my laptop and my desktop, I'm able to pair,
  trust and connect the device, and info reflects these changes, however
  the device never actually connects, it's LED remains blinking fast,
  and the keyboard cannot be used.

  Note, before pairing, I issued the command 'agent KeyboardOnly' and
  'default-agent'.
