1. We followed the instructions of "EVAL-7147.pdf" to install the software, and then plug the USB connector from the USB port of the PC into the mini-USB socket (J3) on the evaluation board.
After following those steps, we found that the "Device ID" is FFF, and the "Silicon Revision" is F.
We got the same result both in win10 64-bit & win7 64-bit OS.
2. Double click the "Evaluation Demo".
3. After few seconds, we got the error message: USB communication failed!
We also got the same result both in win10 64-bit & win7 64-bit OS.
Please help us to solve this problem. Thanks a lot.
