Stand-alone Hub
The hub may immediately be plugged into any USB sys-
tem. The only requirements are that the system has an
operational USB port and that the system has the USB
drivers enabled on the operating system.
When connecting the hub, connect the power supply to the
hub. The bus powered portion of the controller will config-
ure without the power supply, but if devices are to be
attached to the downstream ports, the power supply is
required. Next, connect the upstream port to the USB con-
nector on the computer. Windows will flash a “New Hard-
ware Found” box indicating the “Atmel USB Hub” was
detected and automatically load the generic USB hub driv-
ers. Downstream devices can then be used on the config-
ured hub.

Tip: For your system, make sure USB is enabled in the
BIOS. This may typically be done during the boot-up
process by going into the CMOS setup and checking
the Plug-N-Play settings.
To determine if USB is properly enabled, go into the
“Control Panel” and click on the “System” icon. Under
the Device Manager USB will be listed if setup properly.

Documentation
The application note covers the latest information detailing
how to design a USB hub with the AT43301 chip. Explana-
tions of component selection, USB hub requirements, and
design insights will assist designers in smoothly integrating
a USB hub onto existing or new designs.
By understanding the reference design, layout and compo-
nent selection may be optimized for specific design con-
straints.
