With 5.4 on my dx5150, same onboard USB: APIC enabled in BIOS - nothing detected. APIC disabled in BIOS - USB pen drive detected, but not USB/IDE external laptop drive. AFAIK, onboard USB works fine with Linux. I ended up disabling the onboard USB and adding a NEC USB PCI card, which seems to work fine with OpenBSD 5.4 Regards, Howard E.
