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.

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.
