我在安装指纹驱动时，中途需要禁用下python3-validity这个服务，于是运行systemctl stop python3-validity，提示：Job for python3-validity.service canceled,然后我接着运行systemctl status python3-validity,发现该服务还是开启的：Active: active (running)
于是我systemctl disable python3-validity,重新开机后运行systemctl status python3-validity,发现该服务还是开启的：Active: active (running)
这导致我在安装这一步时：
sudo python3 /usr/share/python-validity/playground/factory-reset.py
始终提示：usb.core.USBError: [Errno 16] Resource busy
