Hi, when I connect the bluetooth BT300 of my Plantronics Headset I can see the following warning: [172855.985539] usb 2-1.3: Warning! Unlikely big volume range (=720), cval->res is probably wrong. [172855.985544] usb 2-1.3: [5] FU [PCM Playback Volume] ch = 1, val = -10240/1280/16 As far as I understand it, the problem may be solved by applying a quirk which is already applied for Logitech webcams. Can somebody help me in finding out the correct value for cval->res. I have no clue which calculations are necessary for that. Thanks in advance.
