1. A USB 2 0 controller can support one or more USB ports on a computer A USB 2 0 controller provides a fixed pool of bandwidth from which isochronous devices can draw Many USB 2 0 equipped Macs come with only one USB 2 0 controller which is shared by all the USB ports built in to the machine All digitizers that plug directly or indirectly into a machine s built in USB 2 0 port must share from the fixed pool of bandwidth offered by that Mac s single USB 2 0 controller If you see a purple display in any VideoGlide video preview window that means that there is insufficient bandwidth remaining in the pool to drive the device using its current settings One or more device settings will have to be adjusted to allow all the devices to work within the available bandwidth of the USB 2 0 controller A USB 2 0 controller can provide approximately 190 megabits of isochronous bandwidth All digitizers plugged into a Mac s built in USB 2 0 ports must draw from this pool A single 640 x 480 stream at 30 frames per second consumes 140 megabits of bandwidth There is no way to have two streams of this size running at the same time when there is only 190 megabits of bandwidth available Either one or both streams need to be reduced in size A stream reduced to 320 x 240 will consume only 35 megabits of bandwidth If this is done to every stream it is theoretically possible to drive up to 4 devices at 30 frames per second However due to device design constraints it w2.
