Hi,
We may have to take a look at the application and understand further to answer this. Before that I would like to understand a few things: how are you downloading the firmware to the device? Does it boot properly and come up with the expected VID/PID in devcie manager? Alos check for the device handle in your application. Did you get the devcie handle properly? See if that is not null. If so, what are the endpoints configured in the firmware, and in application?
Regards,
Gayathri

AN2131 seems to be a full speed device. I am not too sure if using the bulk loop example provided along with Suite would be a good idea.

Hi,
AN2131 as mentioned by NIKL is a full speed device. Thus the bulkloop example that comes with FX2LP DVK (CY3684) or with Cypress SuiteUSB. You will have to use the firmware that comes with EZ USB kit for AN2131. However, you cannot use CyConsole directly (i.e. Download button) to download the firmware, since the CPUCS register and other such registerr are different for FX2LP and FX. You may have to develop your own utility that talks to CyUSB.sys or use script method for downloadng firmware to FX.
One thing to be noted in this regard is that the firmware download to FX must be done in chunks of 64 bytes. we have seen issues when done in chunks gretaer than 64 bytes. Let us know which way you are doing or would like to do.
