error with python 3.8

[ankitkgupta09]

I am using https://github.com/pavel-a/usb-relay-hid/blob/master/Test/test2m.py implementation with python 3.8 same code works fine with Python 2.8, which failed with error "ctypes.ArgumentError: argument 1: <class 'OverflowError'>: int too long to convert"
Any workaround or suggestion to fix this issue?

It looks like there is an error on line 68.

("usb_relay_device_close_all_relay_channel", 'e', None)

should actually be changed to

("usb_relay_device_close_all_relay_channel", 'e', 'h')
