电脑系统为WIN7 64位
python：为python3.6 32位
需要插件PyUSB-1.0.0.tar,pywinusb-0.4.2。
按照的步骤我偷懒了，自己百度一下。
我们先看设备管理的
测试代码如下
#!/usr/bin/python
# -*- coding:utf-8 -*-
import usb.util import sys #USBVID_1C4F&PID_0051 dev = usb.core.find(idVendor= 0x1C4F, idProduct= 0x0051) if dev is None: raise ValueError('Device not found') print(dev) # set the active configuration. With no arguments, the first # configuration will be the active one cfg = dev.get_active_configuration()
测试结果

如果先出现系统无法识别的话
可以参考
https://stackoverflow.com/questions/33972145/pyusb-on-windows-8-1-no-backend-available-how-to-install-libusb
| I downloaded latest libusb windows binaries from here: http://sourceforge.net/projects/libusb/files/libusb-1.0/libusb-1.0.20/libusb-1.0.20.7z/download then I copied libusb1.dll according to this: when you are on 64-bit Windows, MS64dlllibusb-1.0.dll must be copied into C:WindowsSystem32 and (for running 32-bit applications that use libusb) MS32dlllibusb-1.0.dll must be copied into C:WindowsSysWOW64. and then I copied libusb1.lib from binaries to lib dir in python directory and now pyusb works for me. hope it helps. |
