2. Use the USB 3.0 Type-A to Type-B cable to connect the CCG EVK base board to the PC.
3. Connect the 24-V DC power adapter provided with the kit to the CY4521 EZ-PD CCG2 EVK base board
’s power jack J1.
Observe LED2 on the CCG2 daughter card and LED 1 of CCG EVK base board glow green to indicate power is ON, and
LED2 on CCG EVK base board blinks orange to indicate the CCG firmware is executing.
4. Connect the USB Type-C to Type-A adapter provided with the CY4521 EZ-PD CCG2 EVK to the Type-C port (J3) of the
CCG EVK base board.
5. Plug in a USB drive (not provided with the kit) into the Type-C to Type-A adapter board. Verify your setup as shown in
. To evaluate SuperSpeed USB data transfers, it is recommended to use a SuperSpeed USB flash drive.

6. Observe the enumeration of the USB drive connected to the Type-C to Type-A adapter board on the host PC connected
via the CY4521 EZ-PD CCG2 EVK. Verify functionality by accessing files on the connected USB drive from the PC.
7. Disconnect the Type-C to Type-A adapter board and connect it upside down to reconnect the USB drive.
8. Observe the enumeration of the USB drive connected to the Type-C to Type-A adapter board on the PC connected via
the CY4521 EZ-PD CCG2 EVK even with the Type-C to Type-A adapter board flipped. Also observe the SuperSpeed
USB data transfer speed by transferring files. This demonstrates orientation independence of the USB Type-C interface.
5.1.3 Explanation of Functionality
By flipping the USB Type-C to Type-A adapter and reconnecting to the setup, we reversed the orientation of the USB data
channels from the original setup. The reverse order will not affect the enumeration process due to the reversible characteristics
of Type-C connectors.
5.1.4 Common Problems and Troubleshooting
If the demo is not functional, follow these guidelines to troubleshoot.
1. Ensure that the CY4521 EZ-PD CCG2 EVK
’s base board and daughter card are powered by verifying that LED1 on
the CCG EVK base board and LED2 on the CCG2 daughter card are glowing green and LED2 on the CCG EVK
