Hi Nikunj, 

 

Does the USB OTG you use which is the one included in the C5SoC kit? 

If not, you might need to check if the micro USB to USB converter supports OTG as not all the converter are equipped with OTG interface. 

 

Let me know if you have any question. 

Thanks. 

 

Mavis from Terasic.
