I don't use systemd on my arm linux board. I use init.
My system is booting with device tree. But, some node
were destroyed after booting completed. So, when
I use insmod loading the driver, it would match no
device.

Hi there,
If you are using
systemd, you can make your own Target like early.target and
load modules without udev.
But you need to
load modules without device tree, I guess that's not possible.
your system is
booting without device tree?
Thanks,

That's a usb
host driver. As I know, the whole usb subsystem
initialization would take up to 2 seconds while booting. In
another word, that will make the system booting time more
longer. So, I have to build all the usb driver as module and
insert them latter, when the system was usable.
