I am trying to use a logitech keyboard/mouse bluetooth receiver (Logitech, Inc. LX710 Cordless Desktop Laser) to connect to other bluetooth devices to the computer.I am using arch linux. I have read of people doing this, and in ubuntu 10 this was the default behavior. ([h t t p : //ubuntuforums.org/showthread.php?t=1466806&page=1][ubuntu] Logitech MX 5500 Wont Work - Ubuntu Forums[/url]). I have read that i need to use hid2hci to switch modes on the device.

# sudo /lib/udev/hid2hci
error: --devpath= and --method= must be defined

Usage: hid2hci [options]
--mode= mode to switch to [hid|hci] (default hci)
--devpath= sys device path
--method= method to use to switch [csr|logitech-hid|dell]
--help

so i need the sys device path of the Logitch device and i don't know what it is
I have tried
/devices/pci0000:00/0000:00:0a.0/usb2/2-6/2-6:1.0/input/input12

#sudo /lib/udev/hid2hci --devpath=/devices/pci0000:00/0000:00:0a.0/usb2/2-6/2-6:1.0/input/input12 --method=logitech-hid
error: could not find hiddev device node

some useful info i should also mention that i have 2 receivers 1 for my keyboard/mouse the other for Bluetooth
