Guide me please with any suggestions/articles to look for controlling the auxiliary power in wince 4.2 device using vc++.The api provided by vendor is currently not working[It worked previously].The port is not responding to any api calls, I wish to fix it as web searches / contacting the vendor has become fruitless.Its a Samsung Processor.I opened the device and clicked the reset button.Removed the CMOS battery and tried again.
How a auxiliary power control works? Generally where will be the device driver and how it looks in a registry?.
Other port controls[LED,I/O ports with 12V ] through the same api is working.This port has become unresponsive.I wish to understand the auxiliary power control architecture too.
