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. Best regards Oliver -- Oliver Fromme, secnetix GmbH & Co. KG, Marktplatz 29, 85567 Grafing b. M.
