推荐答案

你可能不得不使用libusbdotnet或winusbnet，但没有任何协议文档，这可能是一项长期艰巨的任务，很少/没有奖励



您也可以使用USB - 串行桥并将设备视为串行设备，但不知道您使用的是哪种型号，这是推测



为什么不直接使用SDK？

you would probably have to use either libusbdotnet or winusbnet, but without any documentation of the protocol it could be a long hard task for little/no reward

you might also be able to use a usb - serial bridge and treat the device as a serial device, but without knowing what model you are using, this is speculation

Why not just use the SDK ?
