USB modem huawei E8372h-320

Hello, I ma writing ti you to ask about the compatibility with slate plus and the huawei E8372h-320.
In ROOter by Of Modems and Men aired it was compatible but, when I connect the modem by usb adapter to usb port of my gl inet (slate plus), nothing happens on cellular connection. Could you please help me?

Can you set this one in hilink mode?

When you connect the modem the Slate plus, in the UI did yo see any device?

Hi, there is no chance for allowing the modem to read the modem. It works only with phone tethering or as a repeater connected after my primary router
