python - 尝试使用 USB 将 Nintendo Switch 与 Raspberry 3b+ 进行通信

Question

大家好，一个月前，我的侄女不小心弄坏了我的 Nintendo Switch Controller ( https://www.powera.com/products/pokemon-wired-controller-for-nintendo-switch-pikachu-silhouette/ )，我决定尝试使用树莓派 3b+ 与我的 Nintendo Switch 进行通信...我之前从未用 Python 编程过独自使用了覆盆子，所以我是一个完全的新手。三周后，我得到了这段代码:

import USB
import time

#Test to see if a Nintendo Switch is connected or no
switch = usb.core.find(idVendor=1406)
if switch is None:
    print('Switch Not Detected')
    exit(0)
else:
    print('Switch Conected')
reconect = False

#Don't know why is this for but it helps to connect with the switch
if switch.is_kernel_driver_active(0):
    reconect = True
    switch.detach_kernel_driver(0)

switch.set_configuration()

cfg=switch.get_active_configuration()

interface_number = cfg[(0,0)].bInterfaceNumber
alternate_settting = usb.control.get_interface(switch, interface_number)
intf = usb.util.find_descriptor(cfg, bInterfaceNumber = interface_number,
                                bAlternateSetting = alternate_settting)

ep = usb.util.find_descriptor(intf,custom_match = \
                                  lambda e: \
                              usb.util.endpoint_direction(e.bEndpoindAddress) == \
                              usb.util.ENDPOINT_OUT)

ep.write(b'\x00\x00\x00\x0f\x80\x80\x80\x80\x00')   #Controller not pressed
time.sleep(0.1)
ep.write(b'\x04\x00\x0f\x80\x80\x80\x80\x00')       #Controller "A" button pressed
time.sleep(0.1)
ep.write(b'\x00\x00\x00\x0f\x80\x80\x80\x80\x00')   #Controller not pressed

usb.util.dispose_resources(dev)
if reconectar:
    switch.attach_kernel_driver(0)

print('Communication Finished') 

启动代码后，我收到此错误代码

>>> %FastDebug testedousb.py
Switch Conected
Traceback (most recent call last):
  File "/home/pi/testedousb.py", line 41, in <module>
    alternate_settting = usb.control.get_interface(switch, interface_number)

    data_or_wLength = 1)[0]

    self.__get_timeout(timeout))

    timeout))

    raise USBError(_strerror(ret), ret, _libusb_errno[ret])

谁能解决这个错误？
