Hi, It seems that I'm the only one who buy an HP Elite Presenter Mouse ( http://www8.hp.com/us/en/products/oas/product-detail.html?oid=17872528&jumpid=reg_r1002_usen_c-001_title_r0001 ) This device uses BLE and can be transformed between a mouse and a presenter / gesture mouse. Currently, this "mouse" can only be used for presentation, page up / down is working fine. But neither traditional mouse or gesture mouse is working. I'm on an ubuntu bionic and get some logs from bluez: https://gist.github.com/guilhem/443cf5b588e6c1eb5d38ff7ed1ff5547 Does anyone know if there is a quick fix or quirk to put? I'm available for any other information to debug it. Thanks.
