Insertion of a Board

On insertion of a board, the ENUM# signal is detected and neutralized by the HSC device driver. This event is passed to the PciSwap driver, which detects the slot into which the board is inserted. The parent PCI bus driver is notified for each insertion. The PCI bus driver or PciSwap (or both) invokes the PCI enumerator. New device nodes are created or static nodes are activated. The device-specific driver establishes the connection to the PCI bus. The PCI bus driver invokes a lock method for each activated device node in the PciSwap driver. The slot is declared BUSY.
