Regression with 4G modem on 17.7

[gregober]

There is a regression with 17.7 where 4G modem (we use Huawei) is no longer detected at boot.
We have been testing both version 17.1 where things are working 90% of the time and with 17.7 where it does not work at all.

The USB device is simply randomly detected during startup.

We will test that with FreeBSD 11 and see how It works.

Will try to follow-up and let you know how It goes.
