3.4.5 Identifying USB IDs and Corresponding Devices

If you connected both devices to the same machine and are having trouble identifying which device belongs to which USB port, close the USB2ANY/Aardvark Setup, and unplug one of the USB cables from the computer. ALP should automatically update which USB port is still in use. Take note of the remaining USB ID and note whether the 954EVM or 953EVM is connected to the port. Reconnect the other USB cable and assign the appropriate profile to each ID.

Alternatively, arbitrarily assign profiles to each of the USB IDs and open the device page that is assigned to the 953 by double clicking the name. Select the registers tab, click register 0x00 label I2C_DEVICE_ID, and read the value, shown in #X798.

The default I2C Device ID for the 953 is 0x30. If the value is 0x00 instead of 0x30, you need to switch the profiles for the assigned USB ID and re-verify the Device ID.
