[gentoo-user] Logitech K810 Keyboard On Gentoo?

[Kermit]

Hello all,

    I'v bought this keyboard:
http://www.logitech.com/en-roeu/product/bluetooth-illuminated-keyboard-k810?crid=26

    But I can't used it on Gentoo, I had installed the follow packages:
$ eix blue|grep "^\[I"
[I] net-wireless/bluez
[I] net-wireless/bluez-hcidump
[I] net-wireless/gnome-bluetooth
[I] x11-plugins/gkrellm-bluez

    And with gnome-bluetooth, Apple bluetooth keyboard works well for
me. But when I connect to Logitech K810, it(maybe gnome-bluetooth)
always told me "Setting up 'Logitech K810' failed".

    I saw some one have been used it on ubuntu 12.04:
    http://devasive.blogspot.com/2012/11/ubuntu-1204-persistent-bluetooth-pairing.html

    But I can't find the command such as:
     bluez-test-input
     bluez-simple-agent
     hidd
    and so on.


How can I deal with it?

Thanks
B.R
