This is because the Host Controller implements the necessary subset of the upper
bluetooth layers and translates the HID bluetooth profile to a USB HID
profile. In HID mode there is no need for bluetooth related software on
the computer because, it doesn't even know anything of the bluetooth host
controller. The computer sees just USB HID devices.

I have no hid bt devices, but i think you need libs2 and utils2 from
CVS. Then you need to switch the host controller from HID to HCI mode.
How this is done depends on the Host Controller, I think your Logitech
is CSR based so you need the hid2hci tool.
After switching the mode you have a full featured bluetooth host
controller. Now you should load the matching hci module: hci_usb. The
mechanism of loading unfortunately varies, but if hci_usb isn't
autoloaded, then you can "modprobe hci_usb". Now there should be a hci0
device ("hciconfig hci0").

So you might need create the device node for this device. Just search
the mailing list for command with the matching major/minor numbers. What
bthid you are using? You might take this as guide for getting it run:
