    Abstract: The proposed techniques enable dynamic hardware and software (HW/SW) configurations to enable an expansion card to be adapted for use in various original equipment manufacturer (OEM) devices. The techniques use a software-based solution to detect device modes, states, etc. of a device in which the expansion card is implemented by leveraging the device's system resources. In doing so, the need for dedicated hardware pins and general purpose input-output (GPIO) pins, which are otherwise required to detect the current operating mode of the device using hardware-based solutions, are eliminated.
