Sorry Peter,
I apologize for asking for more help here but I will paste the function below and with my changes.
Please let me known if I am wrong and how to fix it as I new here.
Sorry for Wasting Your Time,
Nick 
static int oxu_reset(struct usb_hcd *hcd)
{
 	struct oxu_hcd *oxu = hcd_to_oxu(hcd);
 	int ret;

 	spin_lock_init(&oxu->mem_lock);
 	INIT_LIST_HEAD(&oxu->urb_list);
	oxu->urb_len = 0;

-	/* FIMXE */
+ 	hcd->self.controller->dma_mask = hcd->regs;

 	if (oxu->is_otg) {
		oxu->caps = hcd->regs + OXU_OTG_CAP_OFFSET;
		oxu->regs = hcd->regs + OXU_OTG_CAP_OFFSET + \
			HC_LENGTH(readl(&oxu->caps->hc_capbase));

 	oxu->sbrn = 0x20;

	ret = oxu_hcd_init(hcd);
	if (ret)
 		return ret;
 
 	return 0;
