Description:SD Client driver provides the Smart card reader driver for the Smart card applications to communicate to the given Smart card through Virtual COM Port. The host controller driver abstracts the SD host controller hardware from the rest of the software components. SD bus driver provides standard APIs that allows the SD client driver to access the SD controller hardware. Bus driver performs the bus transactions to determine the type and class of an SD device. Once the type and class of the hardware is determined, the bus driver loads appropriate SD client driver for the device attached in the SD slot.

OS: Windows Vista/Windows XP

Platform: Custom designed hardware with built-in capabilities

Description:The Consumer IR driver project (CIR) is to implement IR functionality on Windows Media Centre based of Vista and Windows XP operating systems. This project is among the very first implementation of consumer IR ehome applications of Windows Vista. The driver enables the IR Transreceiver that is part of the computer motherboard rather than a separate USB attachment. The following are the salient features of the driver• Control of Windows Media centre and ehome applications• Ability to put the system in standby and resume• Ability to work as an IR blaster ( i.e. learning support was integrated into the

driver which makes the PC as power media extender with the ability to control other devices like STB..etc)

• Fully WLK certified and digital signature
