USB-C communication

Hi all, just wonder, if I want to read data out of a certain device while connecting through usb-c cable how do I do so? Is it the same as using serial port for normal usb connection? but from my device manager, I didnt see any usb-c port when I connect it to my laptop. please help

usb-c ports just show up as USB ports. usb-c is a physical connector, not a signalling protocol: the signalling protocol is USB. There is no logic difference or application difference between using a USB-C port or a USB-A port.

okay but how can I code to connect to the device and read data out from it? The older verison of the device uses micro usb so I can easily identify the port number which in this case is COM6. To connect to the device, I use eps_serial=serial('COM6','BaudRate',57600,'Terminator','LF');

But now the newer version of the device uses usb-c and the port are not shown in my laptop so I like to seek help on how to identify and code them.

By the way thank you for you explanation.

If the device is not showing up in Device Manager then you have one of several possibilities:

• the usb-c port is broken.Try a different device and see if the other device shows up
• the usb-c cable is broken
• the device expects to receive power from the usb-c port but you are not providing enough power for it (especially if you are using a hub). This does depend upon the USB port type as usb-c is rated for higher power than usb-a or usb-b (micro-USB)
• the device is broken. This does not depend upon the USB port type
• the device type was not recognized and no driver was found for it. In such a case normally the Device Manager would list the device, just possibly with numeric codes that you did not recognize. This situation does not depend upon the fact that you used usb-c, as this level depends on the manufacturer and device type codes that were signalled as data, with the port type not being relevant

Alright thank you
