Debugging USB events - Lenovo wacom active pen

I am using an active pen (one that has a battery) on my Touchpad and it has stopped working. I am trying to find out whether the problem is in the hardware or software. The touchscreen is working fine, so it is only the pen/stylus version that is not working. What I have so far: 1. The devices are recognized fine, xcorat@mobilextrem:~xinput --list ... ⎜ ↳ Wacom Co.,Ltd. Pen and multitouch sensor Finger touch id=10 [slave pointer (2)] ⎜ ↳ Wacom Co.,Ltd. Pen and multitouch sensor Pen stylus id=11 [slave pointer (2)] ⎜ ↳ Wacom Co.,Ltd. Pen and multitouch sensor Pen eraser id=17 [slave pointer (2)] ... 2. evemu-record shows events on the touch, but not the pen/stylus. The same thing with probing cat /dev/input/event9 vs cat /dev/input/event8 which are the pen and touch. At this point I feel like it might be the pen itself (i changed the battery :/). Is there any other layer that might be software that I am missing? OS: OpenSUSE Leap 42.3 -- Kernel 4.4.87-25 Device: Touchpad Yoga 14
