Seems the question isn't mundane enough for Ubuntu forum - no one followed; so if I can get some clues from here I will cross post back the solution to Ubuntu Forums. The bluetooth mouse's information: Code: $ udevadm info -a -p `udevadm info -q path /dev/input/mouse3` looking at device '/devices/virtual/misc/uhid/0005:17EF:6060.0005/input/input26/mouse3': KERNEL=="mouse3" SUBSYSTEM=="input" DRIVER=="" looking at parent device '/devices/virtual/misc/uhid/0005:17EF:6060.0005/input/input26': KERNELS=="input26" SUBSYSTEMS=="input" DRIVERS=="" ATTRS{name}=="Lenovo Mice N700" ATTRS{phys}=="B8:8A:60:56:E4:3C" ATTRS{properties}=="0" ATTRS{uniq}=="D5:94:54:38:3D:5D" looking at parent device '/devices/virtual/misc/uhid/0005:17EF:6060.0005': KERNELS=="0005:17EF:6060.0005" SUBSYSTEMS=="hid" DRIVERS=="hid-generic" ATTRS{country}=="00" looking at parent device '/devices/virtual/misc/uhid': KERNELS=="uhid" SUBSYSTEMS=="misc" DRIVERS=="" The udev rules I tried: Code: $ cat /etc/udev/rules.d/lenovo.rules KERNEL=="hidraw*", SUBSYSTEM=="hidraw", ATTRS{uniq}=="D5:94:54:38:3D:5D", SYMLINK+="N700" KERNEL=="hidraw*", SUBSYSTEM=="hidraw", ATTRS{address}=="d5:94:54:38:3d:5d", SYMLINK+="N700" SUBSYSTEM=="input", SUBSYSTEMS=="input", SUBSYSTEMS=="hid", ATTRS{name}=="Lenovo Mice N700", SYMLINK+="N700" None of the three rules are tirggered, since evidently they are not mentioned in syslog (when udev log-priority is set to 'debug') and no /dev/N700 show up. I repeated the test with a USB mouse, and everything worked - the rule is mentioned in syslog, reported as returning successfully, and new /dev symlink showed up. The rule that worked for USB mouse is: SUBSYSTEM=="input", SUBSYSTEMS=="usb", ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c063", SYMLINK+="usbmouse" I wish I can adapt the USB mouse's rule directly for the bluetooth, but of course I can't because bluetooth device doesn't ahve idVendor/idProduct, at least not in the output of `udevadmin info` Using Ubuntu 16.10, Thanks! P.S. My real intention is to disable touchpad when bluetooth mouse is connected. I'm attempting a small task - creating a symlink - before trying that deed. _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
