This doesn't depend on the architecture, rather the type of disk controller. "dmesg | grep ^.d0" will give some clues here. It is also possible that, if the USB controller isn't supported in OpenBSD, that the device won't show up here (yes, even though you booted from it!). As this is OpenBSD 5.6 rather than a -current snapshot, this would probably be the case if it's a USB3 port. In that event, try a different port, try disabling USB3/XHCI in BIOS, or try a -current snapshot instead of 5.6.
