I went ahead and allocated a new device entry for the touchpad and everything is working OK now. On Thu, Jan 26, 2017 at 12:15 PM, tsopdump tsopdump <tsopdump@gmail.com> wrote:
Hi,
I have a Bluetooth Sony MSG-MR5U remote that has a full keyboard and a touchpad. The keyboard works fine in Linux but the touchpad isn't recognized.
I've edited the hid-sony module to enable the touchpad but I've run into a problem where the keyboard stops working when I enable the touchpad. More specifically, if I call input_mt_init_slots with the INPUT_MT_POINTER flag, the touchpad works but the keyboard stops working. If I don't pass this flag, the keyboard works but the touchpad doesn't.
Only one device entry is created and after passing INPUT_MT_POINTER to input_mt_init_slots, /proc/bus/input/devices shows

Do I have to allocate a new device entry using input_allocate_device so the touchpad is using a separate device from the keyboard or is there a way to activate both the touchpad and the keyboard using a single device?
BTW, I'm working with the 4.10.0-rc3+ kernel.
Thanks, Todd
