SYMPTOMS
========

When you use a USB camera with certain PCI video cards in Windows 95 OEM Service
Release version 2.1 (OSR2.1), performance may be reduced or your computer may
seem to stop responding (hang). Video playback may also be affected.

CAUSE
=====

Certain PCI video cards may not work well with isochronous transactions, which
USB cameras require. The video card may require several attempts to complete an
operation.

RESOLUTION
==========

To resolve this problem, use the following steps:

1. In Control Panel, double-click Display.

2. On the Settings tab, click Advanced Properties.

3. On the Performance tab, move the Hardware Acceleration slider to None.

4. Click OK or Close until you return to Control Panel. When you are prompted to
  restart the computer, do so.
