This driver is only for the models that have a USB-C console port
This port is a built-in serial > USB converter, so you can plug it right into your PC
(will need to install the included USB > serial driver)
Examples:
ICX7150
ICX7550
ICX7650
ICX7850


Models that have a USB-Mini console port are NOT USB, and they do not speak USB
It is still an RS232 serial port, just using a USB mini connector
Do NOT attempt to plug this directly to your PC via USB
Examples:
ICX6650
ICX7250
ICX7450
ICX7750

On these switches, you need brocade's USB Mini > DB9/RJ45 serial cable
