I am trying to plug in a device into my Macbook and connect to it to read it's serial port. I know the device connects on baudrate 115200.

Currently, I run the command

ioreg -p IOUSB -l -b | grep -E "@|PortNum|USB Serial Number"

I can see the embedded device plugged in

+-o Root Hub Simulation Simulation@14000000
| +-o iBridge@14200000
| |     "PortNum" = 2
| +-o USB2.0 Hub@14100000
|   |   "PortNum" = 1
|   +-o 4-Port USB 2.0 Hub@14120000 
|   | |   "PortNum" = 2
|   | +-o MBED CMSIS-DAP@14122000
|   |       "PortNum" = 2
|   |       "USB Serial Number" = "024002267822ce0a00000000000000000000000085fb33b2"
|   +-o USB Keyboard           @14110000 
|         "PortNum" = 1
|         "USB Serial Number" = "0000000000000001"

note: There's a tag close to

next to every device's name above, but I removed them for formatting issues (as I don't think they're related to the question). In the event they are, that is the tag for my embedded device).

The Question

How would I find out the MBED device's association in /dev/?

I am trying to find the device MBED CMSIS-DAP@14122000 inside the /dev/ directory, so that I can read its serial output. This is where I am lost.

The end goal is that I could use screen or putty or something similar to:

screen /dev/ttyTHIS_MBED_DEVICE 115200
