Raspberry Camera and GPS not recognized

Question

Raspberry,

I have a raspberry pi 3 model B. Mi goal is to take pictures and get the gps longitude and latitude. I got three cameras to test and a gps. All of them get connected using USB ports.

I am using Python to get this data. The problem is that the devices get not recognized

And I get the following error for the camera:

raise SerialException("could not open port %s: %s" % (self._port, msg))se

SerialException: could not open port /dev/ttyACMO: [Errno 2] No such file or directory: '/dev/ttyACMO'

The gps throws a similar error.

I know the cameras and GPS are Raspberry compatibles but i think something changed

I have done a lot of research and it looks i have to do changes to the UART:

But still i do not know if this is the correct path.

My Mac and Raspberry miss the /dev/ttyACMO.

Thanks in advance.

Hi Jesus, Type lsusb to see if the GPS unit gets detected when you plug it in. Then type ls /dev and see if anything gets added when the device is plugged in (compare it with the output of ls /dev when the device was not plugged in). It could be /dev/ACM0 but it may be something else. Also, your output text says ACM O but it never is ACMO. It could be ACM 0 (you have character 'O' mixed with digit zero). If that is in the Python code or on the command line, it needs to be corrected to match what appears when the device is plugged in.
