OPT3001EVM: What's the usb protocol for SM-USB-DIG of OPT3001EVM?

Part Number: OPT3001EVM

Hello,

Now my OPT3001EVM is working well, and I can read lux value in TI OPT3001EVM software as well.

Currently I am developing a PC tool to read lux value easily with HID communication but I cannot find any command set for reference.

I use USB sniffer tool to see how OPT3001EVM software works and I get the raw data as below :

<1:Write Reg 0x01>

<2:Read Reg 0x00> Lux feedback

But my PC tool was not able to convert lux value with copied command using, the response always shows the following : 

(Looks like the communication is well but the command is incorrect)

I have set sleep time 500ms at least between write reg 0x01 and read reg 0x00.

Can anyone tell me the details command set how to communicate with  SM-USB-DIG board ?

Currently I have no application to open LabView sample code since I use Visual Basic for my development.

Thanks,

Ryan
