Surely I am not the only person who got an Optus ACB03B modem?
Searching the internet it seems Sagemcom is the producer of the modem but this particular modem is not on their display and they don't recognise it.
The modem works nicely but I want a user manual, surely that is a logical thing to ask for?
I am specially interested in the USB socket on that modem and so far nobody has told me what it is used for and how to use it.
Shauna asked in your post 2 weeks ago for more information on that modem as it was not known to her. I can't say I know that one either. The usb port is typically used to charge the device or often can be used to create a wired internet connection.
Edit: If the modem in question is not the wireless 4G type then the usb ports are often used for network storage, network printing or other peripheral devices.
