USB Connection issue

Ok, I am trying out my first BBB, and every video show when you type in your ssh terminal /dev/tty.usbB 115200 it runs the linux, for me that doesn’t happen it say no such file or directory called "/dev/tty.usbA 115200". I have not updated the disk image yet, is that a solution anything will help.

ok one more thing i am on a mac and have downloaded all of the drivers, and that i have been able to connect via the network, for some reason anything to do with the screen command doesnt work

Hi Matt, I suggest you get yourself something like this :
USB 2 TO RS232 Converter

That will allow you access to the bootlog and you can do a lot more.
