I'm using 2.5.30 kernel for a non-pci ohci usbhost controller. I'm already 
pass the point where the virtual roothub is connected/enumerated.
When I attach a new device to my roothub(hub_irq will now be triggered). 
When hub.c calls the usb_new_device to enumerate the new attached device, 
the kernel would now error(internal oops) upon loading. My problem is in the 
part of the code below,I think it errors here... Please help. Thanks.

/usb/core/hcd.c
static int hcd_submit_urb(...)
{
.
.
.
urb=usb_get_urb(urb);
if(urb->dev == hcd->self.root_hub)
status = rh_urb+enqueue(hcd,urb);
else
status = hcd->driver->urb_enqueue(hcd,urb,mem_flags);<--It errors here
return status;

}
