If its your card reader is really the problem, check you MacBook Pro box and there's a disk in there for bootcamp or manual, check it if there are any solution about reinstalling the driver, or bring it back to your Apple store to check it or fix it. Wait while the driver installs, then click Finish to complete the installation. Mac Systems 1. Plug the card reader to an available USB port. Insert the driver CD. Choose Mac folder, double click Realtek Mac OS X Installer in the driver CD.

I have a USB card reader that I use for online banking (Handelsbanken, Sweden) purposes. Ever so often the driver to this card reader stops working and forces me to restart the computer. The broken connection between the driver and the card readers is indicated in several ways:

1. When I connect the card reader to my computer some graphics should appear on the card readers display after a succesful initialization. These graphics are never displayed

2. When I launch the administative application it says the card reader is not connected

I have looked at the files the driver installs in Installer. It installs the following files:

/private/var/db/receipts/com.todos.shbecr.shbecr.pkg.bom/private/var/db/receipts/com.todos.shbecr.shbecr.pkg.plist/usr/libexec/SmartCardServices/drivers/shbecr.bundle/usr/libexec/SmartCardServices/drivers/shbecr.bundle/Contents/usr/libexec/SmartCardServices/drivers/shbecr.bundle/Contents/Info.plist/usr/libexec/SmartCardServices/drivers/shbecr.bundle/Contents/MacOS/usr/libexec/SmartCardServices/drivers/shbecr.bundle/Contents/MacOS/shbecr/usr/libexec/SmartCardServices/drivers/shbecr.bundle/Contents/Resources/usr/libexec/SmartCardServices/drivers/shbecr.bundle/Contents/Resources/English.lproj/usr/libexec/SmartCardServices/drivers/shbecr.bundle/Contents/Resources/English.lproj/InfoPlist.strings

Trying to execute the only binary file above, /usr/libexec/SmartCardServices/drivers/shbecr.bundle/Contents/MacOS/shbecr returns the following error message:

-bash: /usr/libexec/SmartCardServices/drivers/shbecr.bundle/Contents/MacOS/shbecr: cannot execute binary file

file on this binary file returns

/usr/libexec/SmartCardServices/drivers/shbecr.bundle/Contents/MacOS/shbecr: Mach-O fat file with 2 architectures: [ : Mach-O ppc_7400 bundle ] [ I386: Mach-O i386 bundle ]

I can see the card reader in USB Prober

It has been like this for ten years or so and on 5 or more Mac:s I have owned during this period. I am sick of it and wonder if there is a way to restart the driver for the card reader/reset USB ports or similar I can do without restarting the computer every time?

1 Answer

I have made some progress and a partial answer to my question is that it is not the driver that fails but Apple's smart card daemon. Restarting it

has so far solved my problem everytime.

Cac Card Reader For Mac

SOLUTION 1 - Verify if minimum system requirement is met.
SanDisk card readers support Windows Vista, Windows XP SP2 and Windows 2000 SP4, Windows 7.
NOTE: No additional drivers need to be downloaded for the card readers as they are native to the above mentioned supported operating systems.

For Mac users, seeTroubleshooting USB device on Mac

SOLUTION 2 - Verify the reader's status under Device Manager.
STEP 1 - Connect the reader to the PC

NOTE: It is recommended that you plug your card reader to the back USB port on your PC to ensure that there is enough power from the USB port for the card reader to be detected properly.
STEP 2 - Check under Device Manager
1. Right-click My Computer.
2. Select Manage.
3. On the left pane, click Device Manager.
NOTE: The card reader will appear in two places: Disk Drives and Universal Serial Bus controls as USB Mass Storage. If there is a yellow exclamation point (!) or question mark (?) next to the device, try to refresh the drivers.

STEP 3 - Refresh the drivers
1. Right-click the entry with the error mark, select Uninstall.
2. On the top menu, click Action, and then click Scan for hardware changes.
STEP 4 - Verify if the reader is detected
1. Double-click My Computer.
2. Look for the card reader under Devices with removable storage.
SOLUTION 3 - Try other USB ports.
A yellow exclamation point (!) under Device Manager usually means that the device is not receiving enough power. If the reader is not receiving ample amount of power from the USB port, it may not function properly.
SOLUTION 4 - Change the drive letters
NOTE: The SDDR-89, SDDR-189, SDDR-289 reader should show 4 drive letters underMy Computer.
