Almost one month back I had posted this thread but did not get any response
:(. Could you please let me know in case you need some more information on
this before giving your thought.
Since this is an old thread I thought of rewriting the problem once again.
I am installing my mirror driver using devcon.exe, it is getting installed
without any error message but I am not able to find out my device using
EnumDisplayDevices().
*Few observations:*
1.) After reboot driver is getting listed.
2.) So far I have faced this issue with Win7-32/64 bits. It is not happening
with XP-32/64.
Please let me know in case EnumDisplayDevices() is having any known issue
with Win7. Is there any other way to check if driver is present?
