我算是新手，但对 Linux 相当熟悉，但这个让我头疼。我的 ThinkPad 有一个集成的 UPEK 指纹读取器。看起来，这就像反复断开连接和重新连接一样。虽然我希望它能正常工作，但只要让它停止正在做的事情就好了。

Bus 001 Device 116: ID 147e:2016 Upek Biometric Touchchip/Touchstrip Fingerprint Sensor
每次我检查 lsusb 时，它要么不显示，要么有不同的设备号
dmesg 更令我心烦意乱。

dmesg 几乎就是这个东西
我真的非常希望得到任何帮助，让它工作或禁用它，这样它就不会在 dmesg 上乱七八糟
