INITIAL BRING-UP
The USB3503 EVB has a default configuration that allows it to operate as a stand alone
hub. To begin, connect the U.FL connectors to an HSIC host. Then, plug the evaluation
board into the 5V power supply. The USB3503 EVB will enumerate as a Generic USB
Hub with the VID and PID equal to the default values found in the USB3503 data sheet.
The default configuration of the USB3503 is to enumerate as a Self Powered Hub. This
means that, according to the USB 2.0 specification, the downstream ports are only
allowed to provide 500mA of current to the downstream device. Refer to the next sec-
tion for customization options associated with the evaluation kit.

EVALUATION SOFTWARE
The USB3503 EVB supports evaluation software available online that can be used to
configure the USB3503. This software requires the use of a Total Phase Aardvark
USB-I
2
C adapter (not included with the Evaluation Kit). To install the software, run
Setup.exe
. This will install the USB3503 Evaluation Software, the LabVIEW Runtime
engine (to run the executable), and the Total Phase drivers to communicate with the
Aardvark. Once the software has been installed, locate and run the
USB3503 Evalua-
tion.exe
program on the computer. Connect the Aardvark to the USB3503 EVB with
