I made the following change in /lib/udev/rules.d/70-hid2hci.rules and now it works.

KERNEL=="hidraw*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[4abc]|c71[34bc]", \

changed to:

KERNEL=="hiddev*|hidraw*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[4abc]|c71[34bc]", \

I don't understand this, because it seems from the `udevadm monitor` output that my adapter (c70[bc]) really was a hidraw device. However, the results speak for themselves and this change has fixed the problem for me, while maintaining a fairly tight KERNEL condition. I suspect that if other people's Logitech USB Bluetooth dongles are still not working with this patch, then they may want to make a similar change to the previous line in 70-hid2hci.rules, but I am not touching that for now, because it does not affect me.

I remember a while ago, there was only one Logitech rule, and it used the | (or) operator for the KERNEL condition, just like my fix does. Does anyone know why they were separated into different rules? Because, obviously, they were under-matching by doing so.

I have attached a proper diff patch for those who are interested.
