HP Compaq dc7700 Desktop PC Series - Unknown PCI Serial Port in Windows Device Manager


After installing a custom image of Windows XP with SP2 an unknown device pointing to a PCI serial port is showing in Device Manager.

The unknown device has one of the following PCI device IDs: pci\ven_8086%dev_2997%subsys_2801103c&rev_02\3&b1bfb68&0&1b or pci\ven_8086%dev_2997%subsys_2801103c&rev_02.
