Question

如何获取Manufacture Name，Size等USB信息？我正在使用Ubuntu 16。和Python 2.7.12

Answer 1

你有没有试过这样的事情：

busses = usb.busses()
for bus in busses:
   devices = bus.devices
   for dev in devices:
       print (repr(dev))
       print("manufacturer", dev.iManufacturer)
       print("Size", dev.iSize)

注意：我认为只有在一次连接一个USB时它才会起作用

使用此功能，您可以在pyusb中打印所有 USB字符串描述符：制造商字符串描述符，产品字符串描述符，序列号字符串描述符（适用于所有USB设备，包括主机控制器）cf https://www-user.tu-chemnitz.de/~heha/viewchm.php/hs/usb.chm/usb5.htm

import usb

busses = usb.busses()
for bus in busses:
    devices = bus.devices
    for dev in devices:

        manufacturer = usb.util.get_string(dev.dev, dev.dev.iManufacturer)
        print str(manufacturer)
        product = usb.util.get_string(dev.dev, dev.dev.iProduct)
        print str(product)
        serialnumber = usb.util.get_string(dev.dev, dev.dev.iSerialNumber)
        print str(serialnumber)
        print('\n')

你必须以root身份/ sudo来调用它，否则会出现ValueError: The device has no langid错误

您可以使用其名称打印的其他USB属性：

import usb

busses = usb.busses()
for bus in busses:
    devices = bus.devices
    for dev in devices:

        print "  Device class:",dev.dev.bDeviceClass
        print "  Device sub class:",dev.dev.bDeviceSubClass
        print "  Device protocol:",dev.dev.bDeviceProtocol
