It seems your card(surely) has a single UHCI controller, but (maybe) 2
USB ports(I say based on you log output).

I feel it`s stranger to not see any message during the UHCI
initialization, but reboot is normal, if the option ROM don`t do
anything it will fallback to BIOS. I mean by "don`t do anything" if it
doesn`t load the boot sector and/or start executing something when it
finishes the Host Controller initialization.

Your log makes me think you don`t have a MSC device attached to any of
the ports. So I have attached a patch to see if the Root Hub
initialization has successfully finished, could you apply the attached
patch to libpayload and show the output?
