5. Hub Demo Board Description
5.1. ISP1521 80-Pin LQFP Package
The ISP1521 has these port configurations:
• One Hi-Speed USB and USB capable upstream facing port (USB0), and
• Seven Hi-Speed USB and USB capable downstream facing ports (USB1, USB2, USB3, USB4,
USB5, USB6, USB7).
The port numbers are marked near the USB connectors on the silkscreen. The downstream
facing ports USB3, USB4, USB5, USB6 and USB7 can be disabled. Disabling a port will also disable
all higher-number ports. For example, disabling port USB4 will disable ports USB5, USB6 and
USB7 as well. Therefore, apart from port USB7, it is not possible to selectively disable a port
(For example, only USB5.). By design, ports USB1 and USB2 cannot be disabled.
