CyU3PUsbSendEP0Data fail on Timeout
I'm working with the FX3, Slave fifo setup, Control EP(0) and bulk in EP.
I start read data from the Bulk EP and at the same time work with the Control EP. After few transactions the CyU3PUsbSendEP0Data function fails with CY_U3P_ERROR_TIMEOUT error code. From that time all calls to CyU3PUsbSendEP0Data fails. The control OUT direction continue to work. The situation appears more frequently when the FX3 device connect to USB2 port (host side).
I use SDK 1.3.1.
