If you cannot install the USB driver in 2, above |
|
|
|
If USB does not work properly even after you use the procedure under 2) to re-install the driver, it probably means
that the information file (usbdsc.inf) contents were not recorded correctly in the Windows Registry.
Perform the following procedure to re-install the USB driver.
|
|
|
| 1) |
Use the USB cable to connect the camera to your computer. |
|
|
| 2) |
Turn on the camera. Open "My Computer" and check to make sure there is no icon indicating a USB connection. |
|
|
| 3) |
On the "Start" menu, select "Settings," "Control Panel" (Figure 1), "System" (Figure 2), "Hardware" (Figure 3),
and then "Device Manager" (Figure 4).

In the list of device drivers, do you see any CASIO driver name with a question mark (?) or explanation point (!) in front of it
(Figure 5)?

Turn off the camera.
|
|

With some camera models, the power switch may be disabled. In this case, disconnect the USB cable. |
|
|
|
| 6) |
Does the CASIO driver name with the question mark or exclamation point (?CASIO QV DIGITAL, !CASIO DIGITAL CAMERA, etc.)
disappear from the "View devices by type" list (Figure 6)?
|
|
|
|
 |
|

The CASIO driver name that disappears from the "View devices by type" list is the one causing the problem.
|
|
|

Turn the camera back on or reconnect the USB cable.
|
|
|
| 8) |
Select the problem CASIO device driver (?CASIO QV DIGITAL, !CASIO DIGITAL CAMERA, etc.), and then
click [Uninstall] (Figure 7).

After confirming that the problem CASIO device driver is deleted, turn off the camera (or disconnect the USB cable),
and then restart your computer.
|

Go to the CASIO Website and download the Windows 2000 USB Filter Driver (Qv2kux_e.exe).
|
|
|
| 12) |
Double-click the compressed file that you downloaded (Qv2kux_e.exe) to extract it. Extracting the file will create a
folder named "Qv2kux_3" (Figure 9), which contains the following files: Qv2kux.inf, Qv2KUX.SYS, readme.txt.

Note that installing the USB driver in the wrong destination will not only cause installation to fail, it will
also disable plug and play for re-installation. If you make a mistake during installation, be sure to click
the [Back] or [Cancel] button, and then make any necessary corrections.
