EVM Installation
Install the EVM using the following steps:
1. Attach a 5-V, 3-A wall power source to J5. LED D5 should turn on.
2. Turn on switch SW3, LED D8 should turn on.
3. Attach a USB cable between J3 and a USB host. LEDs D6 and D7 should turn on.
(a) If the EVM is attached to a USB 3.0 host, D1 and D4 should turn on.

Troubleshooting
Case 1: Device function(s) are "banged out" in Device Manager.
•
Make sure that the latest updates are installed for the operating system.
•
Make sure that the latest drivers are installed for the host controller.
Case 2: The EVM does not work at all.
•
Verify that all switches are in their default state and the EVM is powered on with a 5-V source with
adequate current to support any bus-powered devices (3 A+).
•
If installed, remove the serial EEPROM from the EEPROM socket. The EVM does not require an
EEPROM to operate.
•
Make sure shunts are installed on J2, J7, and J8.
•
In the case where a 12-V power supply has been attached to the EVM, the fault is non-recoverable.
