If and only if you are using it with softraid, (usually as an encrypted volume), then you would need to detach the softraid device using bioctl -d. But you are almost certainly not doing that. If you are just copying files, and/or using dd to, for example, overwrite a device with zeros or random data, then you don't need to do anything special to use usb storage devices on OpenBSD.
