3G/LTE Modem (Huawei ME909u -521) on boot - USB driver not loading

@nora:

I updated the BIOS of the apu3b4 from legacy 4.0.7.1 to legacy apu3 v4.0.12

What can be done to reslove this issue?

I recommend trying v4.0.16 bios. After the very first tests I've made, it looks promising. The bios seems to be already available on PC Engines' page, I got it directly from their support a few days ago. But I believe it's exactly the same version…

So the problem here is simply that the modem is not given enough time to initialise at boot?

You could try increasing the value of kern.cam.boot_delay or autoboot_delay in loader.conf(.local).
