madhul_36 Apr 22, 2015 7:26 AM (in response to denis.kobelev)Hi,
Can you please make sure that the CyU3PUsbLPMDisable(); API has been called in your firmware?
If not, please call it after the CyU3PConnectState API.
There is a chance that Intel Host force the device to go into a low power mode. Adding this API avoids that.

madhul_36 Apr 23, 2015 2:27 AM (in response to denis.kobelev)Hi,
Are you using the C++ Streamer? If not, please try using the C++ Streamer with an increased timeout value (say around 3500 ms.
Please keep the BURST_LEN paramater as 16 in cyfxslfifosync.h file.
