I have been doing some reorganizing lately, and I ran across a “broken” Smart Card reader.
Download Realtek Card Reader Driver For Windows 10 – Done So, these are the handiest ways by which you can download and update Realtek Card Reader Driver instantly. Through this write-up, we’ve tried to solve your issues related to the Realtek Card Driver. Hopefully, now you have been well aware of how to update & install the Realtek Card. The package provides the installation files for SCM SCR335 USB SmartCard Reader Driver version 4.58.0.0. If the driver is already installed on your system, updating (overwrite-installing) may fix various issues, add new functions, or just upgrade to the available version.
It was “broken” because it would not work in Windows Vista. Personally, I wouldn’t consider “not working in Vista” a reason for something to be “broken.”
Really Broken?
So I began to look deeper into this “broken” SCR, and see what the deal was. It is a SCM Microsystems SCR331.
From the above link, it would appear that they still support the SCR331. So I looked at the support page for some Windows 7 x64 drivers. I found one here:
http://www.scmmicro.com/support/pc-security-support/downloads.html
I chose the appropriate download (for Windows 7 x64) to get started.
So I’ve got the drivers… I must be good to go.
Broken?
Well, I connected the SCR to my system, pointed to the drivers, and voila!
Nothing.
Maybe this darn thing is broken. Maybe Windows 7/Vista just can’t use it.
No way… Why are there drivers to use it, when it isn’t “supported?”
Trial and Error
So I fired up a Windows XP VM, loaded the drivers and voila! It worked. Alright, something is a little strange here.
Then I noticed something… Looking at the downloads page for Windows 7 x64 and Windows XP I noticed something very different between the two.
Look at the firmware section from the download page for Windows 7 x64
Then look at the firmware section from the download page for Windows XP (32bit)
So… There is a firmware update for the device. Good to know. Maybe that’s the fix.
Updating the Firmware
I figured that this wouldn’t work in Windows 7 x64, but what the heck, the SCR was “broken” anyway.
Upon downloading and extracting the .zip file, I ran the included FwUpdate.exe to begin the upgrade process. Surprisingly, no compatibility issues, and it ran without issue.

My firmware was at version 1.40, and this package 5.25. Afterward, the SCR was fully patched to 5.25.
And then afterward:
I added the appropriate drivers to Windows 7 x64, and voila! It worked.
Moral To The Story
I know that these devices are not that expensive, a Google Shopping search lists them around $15 each.
I can only imagine how many of these have been discarded by various entities, because they “didn’t work” with Windows Vista/7. So it would cost an organization with 100 of these, about $1500 to replace them with a similar “supported” device if the prices were comparable.
In short, before something is discarded, be 100% certain is isn’t going to work. It could cost you in the long run.
Now maybe I can see if I can get it to work with VMware View… I guess I’ll start with Jason Langone’s post: How to Configure VMware View 4.5 with US Department of Defense CAC Authentication.
-->This section provides installation information that is specific to smart card reader drivers for Microsoft Windows.
Vendors that supply their own reader drivers should make each driver a member of the SmartCardReader setup class in the INF Version Section of the driver's INF file. Vendors must also add a section to properly configure the smartcard services. For example:
Vendors that supply their own UMDF reader driver need a registry setting to allow PnP filter drivers to sit on top of the UMDF reflector. Specifically, in the driver INF file, this entry is needed:
There are no other special requirements that are associated with installing smart card reader drivers.
