Intel® PII400 MHz processor and above, or equivalent in speed from AMD®, Cyrix® and VIA®, is
recommended.
Generally, the processor usage indicator will vary according to the type and number of applications
launched for exercising USB devices attached. For example, running data transfer tests on two high-speed
(HS) hard disk drives (HDDs) on a P4 at 1.7 GHz, 128 Mbytes DDRAM, Microsoft® Windows® 2000 will
determine a processor usage figure of 30% to 40%. Adding two Original USB cameras and an application
playing MP3 song through Original USB speakers may increase the average processor usage figure up to
70% to 80%. Also, a Hi-Speed USB camera and an Original USB camera running simultaneously will
increase the processor usage up to 100% (depending on resolution settings).
