Transfer commands with EP0. | Cypress Semiconductor
Transfer commands with EP0.
I want to send commands to my device using EP0. But when I try to transfer any data to EP0 in USB Contorl Center it return:
CONTROL OUT transfer
CONTROL OUT transfer failed with Error Code:997
What this mean?
How I can transfer commands for driving my device? I want to do it same as Class-Specific Requests in UVC.
