Subject: [v2 2/5] HID: logitech-hidpp: Enable HID++ for all the Logitech Bluetooth devices
Date: Tue, 30 Aug 2022 13:36:12 +0200 [thread overview]
Message-ID: <20220830113615.4414-2-hadess@hadess.net> (raw)
In-Reply-To: <20220830113615.4414-1-hadess@hadess.net>
Probe for HID++ support over Bluetooth for all the Logitech Bluetooth
devices. 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. This particular bug is tracked at:
https://gitlab.freedesktop.org/upower/upower/-/issues/166
Tested with a Logitech Signature M650 mouse, over Bluetooth
