It's probably sd0e or sd0f.  But I don't think that that's your real 
problem.  I'm going to take a wild guess about what it is.

Nathan has made a change to -current that cleared up a lot of USB 
problems I was having, including some 'endpoint stalled' messages.  For 
fun, try deleting these lines from usb_subr.c:

        /* Clear any stall and make sure DATA0 toggle will be used next. */
        if (UE_GET_ADDR(ep->edesc->bEndpointAddress) != USB_CONTROL_ENDPOINT) {
                err = usbd_clear_endpoint_stall(p);
                /* Some devices reject this command, so ignore a STALL. */
                if (err && err != USBD_STALLED) {
                        printf("usbd_setup_pipe: failed to start endpoint, %s\n"
, usbd_errstr(err));
                        return (err);
                }
        }


Caution -- I'm guessing; I have no idea if that will help you or not.  
But I have 3 different devices that now work and didn't before.
