As Logitech doesn't have a list of Bluetooth devices that support HID++ over Bluetooth, probe every device. The HID++ driver will fall back to plain HID if the device does not support HID++, or to a another device-specific driver if it is part of the unhandled_hidpp_devices array, used in the match function. Note that this change might cause upower to export 2 batteries for certain Bluetooth LE devices which export their battery information through the Bluetooth BATT profile.
