IRQ Conflicts: Freeing an IRQ
Your video capture card requires two system resources: an interrupt and a memory segment. If your system
is not immediately detecting the card, there is a high probability that there is an IRQ conflict involving the
video capture card. In the Windows Device Manager, double-click the Sound, video and game
controllers option. Look for the “U.S. Robotics

Video Capture” item. If there is a yellow circle with an
“x” or an “!” inside, Plug and Play discovered an IRQ conflict during installation. Plug and Play will not
always alert you when such conflicts arise.
If your system indicates such a conflict, follow these steps to rectify the problem:
1. In Device Manager, double-click U.S. Robotics Video Capture. A “U.S. Robotics Video Capture
Properties” window will appear.
2. Click Resources.
3. Write down the setting for the interrupt. (If no interrupt is listed, Windows 95 was unable to find a clear
interrupt. If an interrupt is listed, make sure the interrupt is not also being used by a non-Plug and Play
device or REAL MODE device driver. If it is not, then your problem may be unrelated to an interrupt
conflict.)
