如何使用 pyusb 控制 Xbox 360 游戏手柄上的 LED

Question

我希望使用 pyusb 与有线 xbox 360 游戏手柄进行交互。到目前为止，我可以很好地阅读，但我也想写，这样我就可以让 LED 停止闪烁。

看着here，我应该可以做到，但无论我尝试发送什么消息，我都无法控制 LED。以下是我到目前为止的代码，有什么建议吗？

import usb
dev = usb.core.find(idVendor=1118, idProduct=654)
dev.set_configuration()
readEP = dev[0][(0,0)][0] #endpoint to read from
writeEP = dev[0][(0,0)][1] #endpoint to write to

print readEP #should be: <ENDPOINT 0x81: Interrupt IN>
print writeEP #should be: <ENDPOINT 0x1: Interrupt OUT>

##read the startup messages
for i in range(4): #usually only 4 messages
  data = dev.read(readEP.bEndpointAddress,readEP.wMaxPacketSize,100)
  print len(data) #should be 3

##get initial button/axes state
data = dev.read(readEP.bEndpointAddress,readEP.wMaxPacketSize,100)
print len(data) #should be 20

##Try to set the LED to illuminate just one element (message 0x06).
##Each of the following commented-out attempts fails to leave only the first
##element illuminated and subsequent attempts at reading or writing yields
##"usb.core.USBError: [Errno 5] Input/Output Error"
dev.write(writeEP,'010306',100) 
# dev.write(writeEP,'0\x010306',100) 
# dev.write(writeEP,'66310',100) #decimal value of 0x010306

##attempt to read again
while True:
  data = dev.read(readEP.bEndpointAddress,readEP.wMaxPacketSize,100)

解决了；只需要尝试正在编写的字符串的更多变体。以下是最终奏效的方法：

dev.write(writeEP,"\x01\x03\x06",0)
