我正在学习教程(http://pyusb.sourceforge.net/docs/1.0/tutorial.html)
I am on windows xp sp3, my python version is 2.7 and I downloaded and installed the pyusb-1.0.0-a1.zip
和libusb-win32-bin-1.2.4.0.zip
import usb
工作良好
但是
import usb.core
根本不起作用
上面写着
Traceback (most recent call last):
File "D:pyusb.py", line 1, in <module>
from usb import core
File "D:pyusb.py", line 1, in <module>
from usb import core
ImportError: cannot import name core
有什么解决方案吗?
谢谢
p.s. "from usb import core" this make
Traceback (most recent call last):

完整的源代码在这里
from usb import core
#find device
dev = usb.core.find(idVendor=0x1516, idProduct=0x8628)

dev.set_configuration()
#get an end point instance
ep = usb.util.find_descriptor(

custom_match =

assert ep is not None
