The Alcatel-Lucent OmniSwitch 6860/E (both models E/non-E) support the configuration/connection through USB console. This allows to just use an USB-to-Micro-USB cable and no longer requires specialised USB-to-serial adapters.
If you want to leverage that interface from your Apple Macbook (Pro) running MacOS X (in my case v10.9.2), you'll need to install a UART-driver (Universal Asynchronous Receiver Transmitter). This driver will create a new virtual COM-port / interface that you can use in Minicom/Screen as you used to with your serial-connection, the exact description is: CP210x USB to UART Bridge Virtual COM Port (VCP) driver
You can download the necessary driver, for various operating systems including Apple MacOS X, from the following website:
Example of a connection to the OS6860/E:
During installation the driver will create a new interface:

There is still a „traditional“ RS232 console connection available, that will need an adapter MicroUSB-to-RJ45 + the USB-to-serial adapter on Macbook/Laptop side.
The connection speed is factory default of 9600 BAUD.
