Windows 7 popups installing device driver

Card 2: Unable to detect. Following is gp.exe debug log

>gp -d

SCardConnect("Gemplus USB SmartCard Reader 0", T=*)

Stucks at smart card connect function.

Windows 7 does not popups installing device driver

Also tried using Java Code to connect smart card. Same with Java card. It stucks at connect() function.

My question is why Card 2 is not detected? What can be possible cause? Is related to 32 bit or 64 bit machine or OS?

Answer 1

Got the solution. Actually, Sophos SafeGuard 5.60 is installed on my machine which is blocking reader to read the smart card. I have checked the same card on the machine which does not have Sophos SafeGuard 5.60, it is working fine.
