New version of FUU supports unattended H663 firmware upgrade

FUU “Firmware Upgrade Utility” is SpringCard’s all-in-one software to flash the firmware of most of the product families.

The H663 family (including the H663 OEM module itself, and also the Prox’N’Roll HSP, CrazyWriter HSP, TwistyWriter HSP and CSB HSP) is architectured over an Atmel (now Microchip) MCU, which could be flashed through USB. FUU Supports this family for long, and comes with Atmel DFU (Device Firmware Upgrade) driver for Windows.

Limitation of 10 smart card readers with SCardListReaders

Many customers have noticed that the Windows’ PC/SC subsystem is not able to handle more than 10 readers (or slots in case of multi-slot readers). Actually, the SCardListReaders function -the system call to get the list of available PC/SC readers- is limited to 10 readers max. On old versions of Windows it was possible (although complex) to overcome this limitation by grouping the readers in “reader groups” and querying one group after the other. This is not possible anymore, starting with Windows 8.

Microsoft clearly states in KB #3144446:

Starting in Windows 8, the Windows platform supports a maximum of 10 smartcard readers. If more than 10 smartcard readers are available, APIs such as SCardListReaders return a maximum of 10. All other readers are ignored.

So, sorry, but there’s no way to use more than 10 PC/SC readers (or slots) on a Windows 8 or Windows 10 system. To make things clear, if you connect 2 SpringCard CSB HSP or 2 SpringCard CrazyWriter HSP with the +3 SIM/SAM expansion board, you already have reached the limit.

SpringCard PC/SC SDK VERSION 2016.03

The version 2016.03 of our PC/SC SDK is now available for download:

You can use it with our products in the SpringCard CSB6 Family (CSB6, Prox’N’Roll PC/SC, EasyFinger and CrazyWriter), with our products in the H663 family (Prox’N’Roll HSP PC/SC, CrazyWriter HSP, TwistyWriter HSP, CSB HSP) and our NFC readers/encoders (H512, NFC’Roll).

This SDK is also available on GitHub.

This SDK contains a new version of MemoryCardTool, a new tool called “scriptorxv” and a serie of basic projects for beginners.

SpringCard NetPCSC for Windows


In 2016, SpringCard introduces a new family of network-attached NFC/RFID couplers, providing PC/SC functionnality on top of TCP/IP. The family is built from the SpringCard E663 module, the Ethernet-world counterpart of H663 (for USB world) and K663 (for serial world). The two first products of the family are the TwistyWriter-IP PC/SC, made for OEMs, and the FunkyGate-IP PC/SC, targetting access-control applications. The second one is also available as a FunkyGate-IP+POE PC/SC, where ‘POE’ stands for ‘power-over-Ethernet’, i.e. the device takes its power from the network cable.

To support all the devices based on the E663 module, SpringCard has developed from scratch a PC/SC driver for Windows.

New firmware for all SpringCard PC/SC couplers based on the H663 core

SpringCard has just released a new firmware version, tagged 2.00, for its H663 core.

The H663 core is a versatile contactless+contact module, which supports virtually all proximity/RFID HF chip cards (ISO 14443 & ISO 15693 standards, including Mifare, Calypso, etc), NFC-enabled mobile phones or other objects (ISO 18092, peer-to-peer in initiator mode, passive communication scheme), and could also accept up to 5 contact smartcards (ISO 7816, one ID-1 card and up to 4 SIM/SAM ID-000 cards).

SpringCard H663 is the foundation of the largest family of RFID/NFC USB PC/SC readers on the market:

  • The H663S and H663A “bare” modules (designed respectively for either a Symetrical – balanced or an Asymetrical – unbalanced antenna)
  • The H663-USB OEM PC/SC ready-to-use contactless coupler (H663 core + antenna)
  • The CrazyWriter HSP, a complete multi-slot contactless+5 contact PC/SC coupler made for OEMs
  • The TwistyWriter HSP, a contactless+ID-000 PC/SC coupler made for OEMs
  • The CSB HSP, a desktop PC/SC coupler featuring contactless, 1 smartcard slot and 3 ID-000 slots
  • The Prox’N’Roll HSP, a brand new version of SpringCard’s best selling desktop contactless coupler.

This new firmware version provides only a few new features, but introduces a new software architecture based on FreeRTOS which dramatically increases the device’s performance for a better transaction time – particulary when accessing numerous slots in the same transaction.


How to upgrade

To upgrade your H663-based product with this new version, please refer to our H663/H512 Firmware Upgrade Procedure.

The 2.00 firmware file is here: uc3b0256_rc663_h663_2-00.hex

(note for future readers: please always use the latest firmware version using this permanent link).

From 30/04/2015, all H663-based products will ship with this version (instead of earlier 1.81).

Some new feature

Adding the reader’s serial number to the slot names under Windows

Starting with version 2.00, the H663 family is able to insert the reader’s serial number in the name of the PC/SC readers as exposed by Windows’ SCardListReaders API call. On machines with numerous readers attached, this makes it possible to know which physical reader is actually bound to a logical slot without querying the reader through a SCardControl call.

To enable this feature, download the latest version of MultifConf; create a new project for the H663-product you own (CrazyWriter HSP typically), and in this project scroll down to “Misc. tricks”. Then find the “Insert the serial number in the name of the slots” entry and turn it ON. apply the configuration to the reader(s) (Project -> Write Configuration into Reader), restart the reader, and enjoy!




PC/SC Troubleshooting on Windows

Following our PC/SC installation guide on Windows, you’ve installed the appropriate driver, and made sure the “Smart Card” service is running on your Windows computer.
But still, your PC/SC reader doens’t appear on PC/SC Diagnostic.

Please first check in your device manager that your SpringCard PC/SC reader is properly installed (it should appear under Smart Card Reader).

Now, if the drivers are properly installed, the “Smart Card” service is running, but the reader doesn’t show up on the diagnostic tool, the reason must be one of the following :

  1. A third party security-related software or single-login solution takes full control over the PC/SC subsystem
  2. The computer is either running in a virtual machine or in a remote session on a terminal server
  3. Access to PC/SC readers has been disabled by the corporate administrators through a group policy
  4. A driver from one of our competitors has corrupted the registry

For reasons 1 and 2, SpringCard cannot offer any help.

For reason 3 : you should try to run a copy of our PC/SC Diagnostic tool, located on the C: drive, being logged in as Administrator. If this works, your reader is properly installed.

For reason 4, the problem is in the registry permission for LOCAL_SERVICE :
Open the registry editor (“regedit”) :

  1. Right-click on the key HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Cryptography/Calais and select Permissions…
  2. Click Add.
  3. Click Advanced.
  4. Click Locations.
  5. Click on the computer name and click OK.
  6. In the window ‘Select user or groups’, click on Find now.
  7. Select LOCAL SERVICE.
  8. Click OK.
  9. In the window ‘Select user or groups’, click OK.
  10. In the window ‘Permissions for Calais’, click on LOCAL SERVICE and make sure ‘Full control’ , ‘Read’ and ‘special permissions’ are allowed.
  11. In the window “Advance Security Settings for Calais”, deactivate the options “Inherit from parent the permission entries that apply to child objects…”
  12. When the window “Security” appears, click Copy.
  13. In the window “Advance Security Settings for Calais”, activate the option “Replace permission entries on all child objects with entries shown here that apply to child objects” and click OK.
  14. In the window “Security” click Yes
  15. In the window “Permissions for Calais”, click OK.

Restart the computer.

Accessing Reader’s configuration from command line and in batch mode

All SpringCard PC/SC Readers feature a set of Configuration Registers that allow to alter the Reader behaviour to match a particular hardware setup or end-user requirement.

Editing the configuration is easy thanks to MultiConf, the new versatile configuration tool that covers all SpringCard products. But MultiConf is a GUI-application. When it comes to configuring numerous readers at once (with the same settings of course), a command-line tool, suitable to operate in batch mode, could be preferred.

This is typically the aim of pcscconf, a simple command-line utility (targetting Windows systems).

Getting started with pcscconf

Download pcscconf (and its companion tool pcscinfo) (ZIP)

Extract the ZIP archive in the directory of the choice. There are 3 files in the archive:

  • pcscconf.exe, the tool we’ll be using
  • pcscinfo.exe, a software to retrieve all information regarding the connected readers (version, serial numbers, etc)
  • pcsctool.dll, the library that makes both software work.

Open a command-line box in the directory where you’ve extracted the archive, and at the prompt enter



Reading current configuration


pcscconf -d

to dump the current configuration.


It is also possible to enter

pcscconf -d <Filename>

to dump the configuration to a file. pcscconf uses the same file format as MultiConf.

If the file already exists, use

pcscconf -df <Filename>

to force the overwrite.

Changing a configuration register

Use syntax

pcscconf -s <RegisterAddress>=<RegisterValue>



To erase a register (i.e. restore product’s default value), use syntax

pcscconf -s <RegisterAddress>

Applying a new configuration from a file

Use syntax

pcscconf -u <Filename>

to upload the configuration from the file into the reader.

There’s no confirmation prompt or ‘Are you sure’ dialog box. Be sure to double-check the content of your file before uploading it into the reader.


Do not forget…

Changing a reader’s configuration will change its behaviour! You’re using this software at one risk. Always refer to the reader’s detailed Developer’s Guide or use MultiConf to choose the appropriate values.

Some registers play a special role and are therefore protected before delivery. This is the case of registers C0 and F0 to FF. Trying to write in one of these registers will always fail.

pcscconf targets the SpringCard PC/SC Readers only (and not the RFID Scanners, /RDR family and access control readers, nor the Legacy products).

pcscconf is able to work with only one PC/SC Reader at once. If you run pcscconf with two readers or more connected to your computer, the software will issue a warning and exit.
