RB751 and USB modem

Hi all,

I´m newbie in mikrotik. I need to use mikrotik routerboard RB751 with USB modem Huawei K4305 - this modem is not supported but someone from mikrotik told me that it will be ok. So I found on youtube some tutorial how to set it. But in menu PPP - Client - Ports I dont have USB, I have there only unknown. It is because the modem is not supported or I´m making something wrong?

Thank you for help.

I’m noob too, but this might help

Hello,
i’ve tried this USB modem on RB751 with RouterOS 6.1 and it didn’t worked for me.

Will this modem be supported in future ROS versions?

Many thanks.
