Card reader not being detected by the PC

Why can't my card reader/writer be detected by my PC?

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.

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.
