The devices only appear to work in the raw mode. hid2hci --method=logitech-hid only stops the device from working because the hardware doesn't actually support it (supplementary: likely a too early BT implementation, it has it's own bluetooth usb device which is to talk with the mouse and keyboard but it seems you can't use it with other devices, and the mouse and keyboard don't work with other BT dongles, at least as far as I have tried).

Are you talking about the following rules:
# Logitech devices
KERNEL=="hiddev*", ATTRS{idVendor}=="046d",
ATTRS{idProduct}=="c70[345abce]|c71[34bc]", \
RUN+="hid2hci --method=logitech-hid --devpath=%p"
I don't know who came up with these rules but it definitely hasn't
changed in a long long time:
