推荐答案

从你的问题我认为你需要一个用户模式应用程序，它应该通过USB读/写命令。（我想你不需要写一个驱动程序）。



如果你在Windows系统上使用WinUSB是一个很好的选择，试试，如何使用WinUSB函数（Windows驱动程序）访问USB设备 [ ^ ]链接应该可以帮助你开始。



基于Linux的系统libusb [ ^ ]是个不错的选择。



请记住，您发送到USB设备的命令必须由该目标设备处理。

From your question I think you will need a user mode application which should read/write commands through USB.(I guess you don't need to write a driver).

If you are on Windows System using WinUSB is a good option to try out, How to Access a USB Device by Using WinUSB Functions (Windows Drivers)[^] link should get you started.

On Linux based system libusb[^] is a good option.

Remember the commands you send to the USB device have to processed by that target device.
