PyUSB send HID report

I'm desperately trying to send a simple report to a HID-device using PyUSB.

Using "SimpleHIDwrite" I confirmed, that the device works just as expected. I want to send this data:

report ID: 00

data: [00, 04, 04, FF, FF, FF, 00, 00]

sending data using SimpleHIDwrite

I'm quite new to python and USB and I can't figure out how to do this using dev.ctrl_transfer or dev.write.

Also, there are some posts about sending data to HID devices, but I couldn't figure out how to solve my problem.

Could anybody please be so kind to point me in the right direction?

Thank you very much!

Here are some more details:

 # based on https://github.com/walac/pyusb/blob/master/docs/tutorial.rst

import usb.core
import usb.util

# find our device
# dev = usb.core.find(idVendor=0xfffe, idProduct=0x0001)
dev = usb.core.find(idVendor=0x1781, idProduct=0x8c0)


# was it found?
if dev is None:
    raise ValueError('Device not found')

dev.set_configuration()

cfg=dev[0]
intf=cfg[(0,0)]
ep=intf[0]

# dev.write(ep.bEndpointAddress, [0x00, 0x00,0x04,0x04,0xFF,0xFF,0xFF,0x00, 0x00], 1000)
# dev.ctrl_transfer(bmRequestType, bRequest, wValue=0, wIndex=0, data_or_wLength=None, timeout=None)

print("print ep")
print(ep)
print("print cfg")
print(cfg)
print("print intf")
print(intf)

And the result of the script above is this:
