Bastien, Jiri,
Commit 532223c8ac57 ("HID: logitech-hidpp: Enable HID++ for all the Logitech
Bluetooth devices") caused my Logitech Bluetooth mouse to become unusable.
Appended is the change I need to make it work again (note that adding the
device ID to unhandled_hidpp_devices[] doesn't help, so there must be some
significant enough difference in how the two cases are handled in the stack).
Here's what I get in the log without the patch below:

The only difference seems to be that in the former case the logitech-hidpp
driver tries to bind to the device, but I guess that is expected. However,
when the device ID is added to unhandled_hidpp_devices[], the messages look
exactly like in the "good" case, but the mouse still doesn't work.
Thanks,
Rafael
