推荐答案
如果要阻止所有USB设备(大容量存储),请阅读此解决方案.
禁用/启用USB阻止后重新扫描USB设备-通过注册表 [使用C#开发USB存储设备保护工具 [ ^ ]
另一种方法是将应用程序锁定在DeviceArrival,读取连接设备的VID/PID,将其阻止,要求输入密码,如果密码正确,则将其取消阻止.
希望有帮助.

Hi,
if you want to block all usb devices (mass storage), please read this solution.
Re-Scanning USB Devices after disabling/enabling USB-Block-By-Registry[^]
CP-Article:
Developing a USB Storage Device Protection Tool with C#[^]
Another way could be to lock your application at DeviceArrival, read the VID/PID of attached device, block it, ask for password and if it''s correct, unblock it.
Hope that helps.
