4. Troubleshooting
Problem: You receive the message, "USB port not found. Your system
either does not have a USB port or USB is not enabled in BIOS."
Solution: Verify that your computer has a USB port. If the port exists, enable it
in the system BIOS by running your computer's BIOS setup program.
Problem: Dark pictures from the PC Camera DS3303U
Solution: If you are getting very dark pictures from your PC Camera DS3303U,
then it is either due to there being insufficient light for the PC Camera DS3303U
or partial covering of the lens.
Problem: Insufficient Light
Solution: Like camcorders (and even Digital Still Camera), the PC Camera
DS3303U sensor requires a certain light level to produce good pictures. If you
are getting dark images or if the colors in the images you are getting are poor,
then try either to increase the lighting in the room or consider lighting the
subject directly.
Using the PC Camera DS3303U in a position that is lit with sunlight should give
good results. It is better to position the PC Camera DS3303U with the window
(or indeed any light source) outside of the field of view, so that the exposure
level is set so as to get the best picture for the scene. If the light source comes
within the field of view, the PC Camera DS3303U will try to settle at a
compromise between the best exposure setting for the light source itself and
the rest of the scene - this is rarely a good level for the rest of the scene. If you
are not using the PC Camera DS3303U in a naturally well-lit position then
consider using a desk lamp or some other artificial light source.
Problem: Installation does not finish properly.
Solution: Unplug the camera first, then un-install the software. Close all other
open applications on the computer. Then install software again.
Problem: The video window has flashing vertical or horizontal colored
lines.
