OPT8241-CDK-EVM: Fail to open device error

Part Number: OPT8241-CDK-EVM

Hi, There.

I recently purchased OPT8241-CDK-EVM board and tried to operate it yesterday, with new power supply.

but Voxel Viewer(v0.9.10) software can't communicate with EVM board. 

 

first wired thing i have notice is, this EVM board does not have any Serial number or other number on USB address. 

and it shows error.

Thus I have doubt on Driver, but that looks fine.

I also absolutely check Board LEDs and all 3 LED is on looks okay.

 

Thus, now i have no idea what should I do and have some concern I have defective one.

Would you help me to figure out what is wrong on this EVM board?

 

Thank you.

Best regards,

SK.
