推荐答案

您不这样做.您正在尝试将USB端口与串行或并行端口相同.你不能那样做.

USB是BUS，而不是端口.您可以与连接到USB的设备进行通讯，而无需与端口本身进行通讯.

该如何操作取决于您要与之交谈的设备及其通常通过某些设备驱动程序公开的接口.

You don''t do this. You''re trying to treat the USB port the same as a serial or parallel port. You can''t do that.

USB is a BUS, not a port. You talk to the devices that are attached to USB, no to the port itself.

How you do that depends on the device you want to talk to and the interfaces it exposes, normally through some device driver.

这不像串行通信那么简单.

This is not as trivial as serial communications.
