Hi,

Basically there are very few changes in the EHCI/OHCI drivers between 
10.3 and 12.0 . Does re-plugging the USB device make it appear again?

If you don't see any messages like "failed to enumerate" ... it means 
the device is not visible at all to the USB host controller. Changing 
values under:

sysctl -a hw.usb.timings

Might affect the situation. In 12.0 there is a new system wide feature 
called early AP startup, which kicks multithreading much earlier. Maybe 
it affects the boot timing somehow.

When FreeBSD 12.0 is booted, you might also want to try to do a reset on 
the HUB, where I guess all devices are connected:

usbconfig -d X.Y reset

where X.Y are the numbers in ugenX.Y .
