Today's implementation does an exact device path match to check whether the device path of a console is in ConIn/ConOut/ErrOut. But that doesn't work for the USB keyboard. Because when a platform have multiple USB port, ConIn needs to carry all device paths corresponding to each port. Even worse, today's BDS core logic removes the device path from ConIn/ConOut/ErrOut when the connection to that device path fails. So if user switches the USB keyboard from one port to another across boot, the USB keyboard doesn't work in the second boot. ConPlatform driver solved this problem by adding the IsHotPlugDevice() function. So that for USB keyboard, ConPlatform doesn't care whether its device path is in ConIn or not. But the rule is too loose, and now causes platform BDS cannot control whether to enable USB keyboard as an active console. The patch changes ConPlatform to support USB short-form device path when checking whether the device path of a console is in ConIn/ConOut/ErrOut. The logic to always accept USB/PCCARD device as active console is removed.
