If you plug a RTL8188CUS USB wireless adapter in port #1 it will behave as an AP. If you use port #2 it is configured as a station. The users will not even have access to the device in somce cases unless it runs as an AP. No LCD! No network!</div><div><br></div><div>If I use USB to serial adapters then I assign port names based on Bus/Device. The user will then use a temp probe on one, maybe a terminal on another, and some sites even have a UPS that I am interfacing via USB serial.</div><div><br></div><div>Another thing I noticed is that if I unplug the USB modem and plug back in it will be assigned 001/005. On the older hardware this is not the case.
