I have installed OAK-CM4-POE-V2 onto the sd card and inserted the card into rPI 4. I have OAK-D camera connected to the rPI. When I tried to run the mobileNet>rgb_mobilenet.py file, it gives following error.
'''

python: ../../libusb/os/threads_posix.h:46: usbi_mutex_lock: Assertion

How can I solve this issue?
