Help me with t99w175 and hap ac2

Hello everyone!

I bought myself a mikrotik hap ac2, and a t99w175 modem (modified for usb, 5G is not particularly needed, LTE is enough). When I connect it to the mikrotik, it is not even recognized as a usb device (the logs are empty, when I connect the disk, it shows that the drive is connected, and when I connect the modem nothing apears in logs).

At the same time, both the modem and the adapter are working (it works with my keenetic, on a linux PC it is recognized as a qmi_wwan modem).

Device: mikrotik hap ac2(router os 7.20) + t99w175

Please help me, how can I make this modem work on mikrotik?
