If I plug in the diNovo Mini stick lsusb says

ID 046d:c71f Logitech, Inc. diNovo Mini Wireless Keyboard
ID 046d:c71e Logitech, Inc. 
ID 046d:0b07 Logitech, Inc. 

If I keep the red button pressed when plugging in, I get

ID 046d:c709 Logitech, Inc. BT Mini-Receiver (HCI mode)
ID 046d:0b07 Logitech, Inc. 

Now, if this used in a docking station, then the laptop is undocked/docked makes the stick revert from the second to the first. And, the first is useless to me. Is there a way to induce the stick to change to a BT stick while plugged in? I observe the 046d:0b07 device being present in both cases so perhaps that could be talked to.

The utility is called hid2hci and it's in the bluez package you need to install anyways for Bluetooth. (On Arch, it's in bluez-hid2hci)

For other sticks the change is completely automatic. But this stick is not recognized by the relevant udev rule. So I did sudo cp /lib/udev/rules.d/97-hid2hci.rules /etc/udev/rules.d/ and then changed the logitech line:

KERNEL=="hiddev*", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c70[345abce]|c71[34bcf]", \
  RUN+="hid2hci --method=logitech-hid --devpath=%p"

Note the f at the end of the first line, that's what was missing.
