一周前，手写笔以某种方式在设备之间添加了（我已经几个月没有自己的手写笔了），并且每次笔记本电脑启动时都会向我发送垃圾邮件：
$ sudo libinput debug-events | grep event5
-event5 DEVICE_ADDED ELAN9009:00 04F3:2E36 seat0 default group5 cap:t size 300x184mm ntouches 10 calib
-event5 TOUCH_DOWN +69.894s 0 (0) 85.20/92.85 (255.67/170.92mm)
event5 TOUCH_FRAME +69.894s
-event5 TOUCH_UP +69.909s 0 (0)
event5 TOUCH_FRAME +69.909s
-event5 TOUCH_DOWN +96.373s 0 (0) 85.23/92.89 (255.75/171.00mm)

event5 TOUCH_FRAME +115.374s
-event5 TOUCH_DOWN +129.771s 0 (0) 85.23/92.98 (255.75/171.17mm)
event5 TOUCH_FRAME +129.771s
event5 TOUCH_UP +129.786s 0 (0)
event5 TOUCH_FRAME +129.786s
-event5 TOUCH_DOWN +138.171s 0 (0) 85.23/92.76 (255.75/170.75mm)
因此，每次笔记本电脑重新启动时都会添加设备。
快速解决方案是每个笔记本电脑启动调用：
$ xinput disable "ELAN9009:00 04F3:2E36
$ xinput disable "ELAN9009:00 04F3:2E36 Stylus
$ xinput # when are devices disabled
...
∼ ELAN9009:00 04F3:2E36 id=9 [floating slave]
∼ ELAN9009:00 04F3:2E36 Stylus id=10 [floating slave]
...
$ cat /proc/bus/input/devices
I: Bus=0018 Vendor=04f3 Product=2e36 Version=0100
N: Name="ELAN9009:00 04F3:2E36"

B: PROP=2
B: EV=1b
B: KEY=400 0 0 0 0 0
B: ABS=3273800000000003
B: MSC=20
现在我尝试弄清楚发生了什么以及如何永久删除这个不真实的设备。任何想法？
