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

I: Bus=0005 Vendor=0609 Product=0368 Version=0111 N: Name="SONY NSG-MR5-U" P: Phys=00:1a:7d:da:71:0a S: Sysfs=/devices/pci0000:00/0000:00:0b.0/usb2/2-5/2-5:1.0/ bluetooth/hci0/hci0:70/0005:0609:0368.0007/input/input12 U: Uniq=00:01:90:d2:1b:7b H: Handlers=sysrq kbd mouse1 event7 B: PROP=5 B: EV=10001f B: KEY=3007f 0 0 483ffff17aff32d bf54444600002420 10001 1130f938b17c007 ffff7bfad9415fff febeffdfffefffff fffffffffffffffe B: REL=40 B: ABS=2738f0100000003 B: MSC=10

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
