USB port / LTE initialization

Hello.
Is there any way to search/reinitialize LTE donge on USB port?

The only way I found so far is to soft reboot my mikrotik, while dongle ( LTE hilink) is plugged in and active.
Simple power reset on USB port does not work, after that donge is starting, but LTE interface is absent and mikrotik does not see it nor discover.
Plugging and unplugging physically from USB gives zero effect, it is not discovered.
However, while processing whole reboot from zero, LTE intereface is correctly recognized and created. Aso, USB is present in resources, but port is empty.

The final question is, how to search / force create dynamic LTE connection, and second one is how to reinitialize USB?
