我的问题类似于Will所建议的“在Python中简单地读取/写入USB HID设备？”，但是遵循它我没有得到任何结果。问题：我正在尝试处理Oregon WMRS200 Meteo站，它实现了一个usb连接作为HID设备。我开始调整/简化下面列出的'raw data.py'提供的示例
from time import sleep
from msvcrt import kbhit
import pywinusb.hid as hid
def sample_handler(data):
print("Raw data: {0}".format(data))
def raw_test():
device = (hid.HidDeviceFilter (vendor_id =0x0fde , product_id = 0xca01). \
get_devices())[0]
device.open()
#set custom raw data handler
device.set_raw_data_handler(sample_handler)
print("\nWaiting for data...\nPress any (system keyboard) key to stop...")
while not kbhit() and device.is_plugged():
#just keep the device opened to receive events
sleep(0.5)
device.close()
return
if __name__ == '__main__':
raw_test()
数据的传输没有开始。我在网上发现系统必须初始化一次（在重置或pw失败后）发送缓冲区 0x20 0x00 0x08 0x01 0x00 0x00 0x00 0x00 问题是我不知道如何发送它。做一些事情，比如发送报告（如上面引用的例子），得不到任何结果。
如果在重置之后我开始和停止一旦原始的俄勒冈一切开始工作，即通道以某种方式初始化。在通信通道上安装嗅探器我想我看到字节串转到设备，但是，我怎么能发送它？ 这是原始sw的嗅探器的输出。我想在URB 9-10中可以看到字节模式进入设备。

从URB 11 - - ＆gt;正常传输也从我的示例脚本开始。
我希望我已经足够明确了.....感谢您的帮助。

对于发送RAW数据（没有HID描述符管理的报告），您可以使用“device.send_output_report（）”，将任何列表作为参数传递（或者为了获得更好的性能，您可以传递ctypes.c_ubyte数组。
