Hi,
I have tried to modify your UVC firmware and have property page (the one lets you adjust brightness, hue, sharpness...etc) displayed and work when running AmCap.exe but I am only able to make property page displayed but all properties scroll bar are grey-out and cannot be adjuested. Any idea what might be the root cause of this issue ? Thanks in advance for any help.
Following is what I have done.

uint32_t input)

uint32_t flag;
uint16_t readCount;
