Origianlly, i was expected data is like this

0 1 2 3 4 5 6 ...

but i can't it. Why happend this result data?

Hi :

I want to implemented a UVC( USB video class) board using 68013a, so I can use the USBvideo.sys driver by Windows XP;

According to UVC hardware spec, several changes needed to be done with the device and configure descriptors,

My change is done with a reference of the below code:

const uint8_t CyFxUSBHSConfigDscr[] =

};

The results shows that the driver is not correctly setup at WIndows, it shows" USB composite device" in the device manager with yellow "!";

my question is :

how to correctly change the configure descriptors and other codes in the fireware so that Windows can recognize the device as UVC ; Thanks

USB low-full-high speed peripherals

Loading the firmware through driver?

Solved

Can anyone point me to the documentation on this?

Thanks
