Quick Solution: open device manager, disable smartcard device(you'll have to catch it before it disappears) and install the smartcard software.(download link is at bottom of this article)
I recently had resolved issue with my smartcard CAC reader (SCR3310 V2.0) after a Microsoft Windows Update / Optional Driver Update was installed. After the update, I noticed this issue: In windows device manager, the USB smartcard device was continually being added and removed. If I left the USB smartcard reader plugged in, eventually this would give me the "blue screen of death".
The driver's files are located here:
Driver Date: 12/06/2012
C:\Windows\system32\drivers\S3XXx64.sys
C:\Windows\System32\DRIVERS\scfilter.sys (this file is from Microsoft and can only be removed by the TrustedInstaller user)
There is not a Microsoft KB associated with this update. I pasted the update details below.
I tried uninstalling the driver and installing the latest driver from the manufacturers website.
You can download the driver here from the link below:
Download SCR3xxx_win_installer_V8.51.zip
But no luck.
It was still constantly uninstalling and reinstalling the device. With quick timing I was able to disable the smartcard device in Windows device manager. Doing so allowed it stay in device manager without reinstalling itself constantly. I then ran the manufacturer driver installer to repair the driver and everything finally seems to be working again.
Issue resolved.
Note: The exact model of the smartcard reader is SCR3310 V2.0

Where do I find a working Pure Edge viewer for mac OS X? Finally there is a Solution that works. (Scroll down for a working solution download.)
Normally you would install PureEdge forms viewer on a Microsoft Windows machine but if you own a Mac, it is a not officially supported directly on OS X.
I downloaded an Intel Mac version of PureEdge viewer from grants.gov but when I tried to install it but I got this error:

I put together a work around to get the installation to work but there were functional problems with form navagation and printing. Thomas Kearney from AEONCONCEPTS.COM put together a good emulator package that allows you to run a more updated version of PURE Edge 6.5 Viewer on your Intel
based mac. It uses the opensource WineSkin project. Click the "Download Here" button below.
