That's expected and a known problem. The card contains
an OHCI controller, but the ohci(4) driver doesn't support
detaching. I think that's also the reason why you have
to compile ohci statically in your kernel, there's no
module for it.
Solution: Don't unplug the card.
The problem is supposed to be fixed with usb4bsd, but I
haven't tried it myself.
