USB设备识别 [英] usb device identification

问题描述

我在ubuntu 9.04上使用python 说我有两个USB设备连接到一台PC.我如何识别python代码中的设备.....例如

如果USB端口ID == A 将数据写入设备1 如果USB端口ID == B 将数据写入设备2

任何想法....

解决方案

您是否尝试过 pyUsb ? 使用以下方式安装:

 pip install pyusb
 

以下是您可以做什么的摘要:

 import usb
busses = usb.busses()
for bus in busses:
    devices = bus.devices
    for dev in devices:
        print("Device:", dev.filename)
        print("  idVendor: %d (0x%04x)" % (dev.idVendor, dev.idVendor))
        print("  idProduct: %d (0x%04x)" % (dev.idProduct, dev.idProduct))
 

这里 pyUsb的好指南.

有关更多文档，请使用带有dir()和help()的Python交互模式.

    devices = bus.devices
    for dev in devices:
        print("Device:", dev.filename)
        print("  idVendor: %d (0x%04x)" % (dev.idVendor, dev.idVendor))
        print("  idProduct: %d (0x%04x)" % (dev.idProduct, dev.idProduct))

Here a good tutorial of pyUsb.

For more documentation, use Python interactive mode with dir() and help().
