During the boot-process of my SG115 appliance with OPNsense I stubled over a issue with the configuration of the BIOS settings of the appliance. During the initialization of USB, the kernel died and moved over to the debug-mode leaving the installation of OPNsense unfinished.

While searching through the internet, I stumbeled over a post at reddit of one claiming a similar issue while running pfSense on the SG115 appliance. The trick is to disable the “Port 60/64 Emulation” in the USB settings in the BIOS. Once the emulation is disabled, the boot-process works as desired.
The configuration option can be found in the following path within the BIOS:
BIOS -> Advanced -> USB Configuration -> Port 60/64 Emulation = Disabled
