example to use the diepctl register for usb otg peripheral in python

To use the diepctl register for USB otg peripheral with Python, you can use the pyusb library. You need to first install this library using pip.

main.py
import usb.core

# find the device
dev = usb.core.find(idVendor=0xdead, idProduct=0xbeef)

# get the endpoint object
configuration = dev.get_active_configuration()
interface = configuration[(0,0)]
endpoint = interface[0]

# write data to endpoint
data = "some data"
endpoint.write(data)

In the above code snippet, you first find the desired USB device using its vendor id and product id. You then get the active configuration and interface, and finally get the endpoint object for the device. You can then use the write method of the endpoint object to send data to the device.

Note that the vendor id and product id should be replaced with the actual values for your device.
