The following question is about an HCD:
Why is it that when I try to allocate an IO region (io port) during the
reset function it fails (pretty ugly), while it succeeds when I do
exactly the same thing at the start function? I've looked at
usb_hcd_pci_probe() and the allocation of the first region (UHCI case,
i.e. no HCD_MEMORY flag), happens before the call of driver->reset
function, so I don't see why I can't allocate at that time.
Here's what I want to do:
struct isp1160_hcd *isp1160 = hcd_to_isp1160 (hcd);
struct pci_dev *pdev = NULL;
if(hcd->self.controller &&(hcd->self.controller->bus == &pci_bus_type))
pdev = to_pci_dev(hcd->self.controller);
if (pci_request_region (pdev, 2, (char *) hcd_name))
return -ENOMEM;
Any ideas???
