I am trying to implement a USB microphone (for testing both ADC accuracy and USB feature) device, the PSoC enumeration is working fine.
I am not able to find any documentation on how to implement the ISO data transfer. I tried using USBFS_1_LoadInEP API which does not work. Surprisingly the device does not even raise any interrupt nor it used the endpoint buffer for data ISO data transfer.
Also the device is sending empty packets when I start recording in PC, I am not sure which data buffer to use for this data transfer.
Please let me know if any one has used ISO transfer. Any advice on how should I proceed?
