Question

我的代码是获取有关插入USB端口的设备的所有详细信息。但是，当我运行程序时，我收到以下错误：

ImportError: No module named backend.libusb10

有人可以解释一下吗？我检查了我的site-packages文件夹，我有后端。提前谢谢：）

这是我的代码

import usb.core
import usb.util
import usb

# find our device
dev = usb.core.find(find_all=True)
busses = usb.busses()
# was it found?
if dev is None:
    raise ValueError('Device not found')

for bus in busses:
    devices = bus.devices
    for dev in devices:
        try:
            _name = usb.util.get_string(dev.dev, 19, 1)
        except:
            continue
        dev.set_configuration()
        cfg = dev.get_active_configuration()
        interface_number = cfg[(0,0)].bInterfaceNumber
        alternate_settting = usb.control.get_interface(interface_number)
        print "Device name:",_name
        print "Device:", dev.filename
        print "  idVendor:",hex(dev.idVendor)
        print "  idProduct:",hex(dev.idProduct)
        for config in dev.configurations:
            print "  Configuration:", config.value
            print "    Total length:", config.totalLength 
            print "    selfPowered:", config.selfPowered
            print "    remoteWakeup:", config.remoteWakeup
            print "    maxPower:", config.maxPower
        print

也许是因为你正在开发Windows。尝试切换到ubuntu。在我的机器上试过你的代码，就像一个魅力。

步骤：

从http://sourceforge.net/projects/pyusb/
解压缩zip文件，从终端进入该文件夹并输入 “python setup.py install”
继续你正在做的事情。

为什么我得到这个 - ＆gt; importError：没有名为backend.libusb10的模块
