I'm trying to send standard control requests such as brightness adjustment via AMCAP.
I've modified PU descriptor for supporting brightness control..
After adjusting brightness in AMCAP, I suppose there should be a callback sent to CyFxUVCApplnUSBSetupCB but I got nothing.
The only callbacks are received while UVC initialing those are GET_INFO, GET_MIN, GET_MAX, etc.
May I know is there any thing I missed and what value should I return to host when receiving GET_INFO?
I found where the problem is.
When receiving GET_INFO, I should return (SUPPORT_GET | SUPPORT_SET) to host where SUPPORT_GET is 0x01 and SUPPORT_SET is 0x02.
