It works a lot better now with many devices, but I've been getting some occasional bluetoothd journalctl errors line-by-line with my mouse, that read:
Code: Select all
profiles/input/hog-lib.c:report_value_cb() bt_uhid_send: Invalid argument (22)
The bluetooth is Atheros AR9462+Atheros AR3012 Bluetooth, using the firmware-atheros proprietary drivers/firmware.
And my mouse is the Elecom DEFT Pro Trackball Mouse (M-DPT1MRXBK) used over Bluetooth. Note that wired and 2.4 GHz work perfectly fine.
