Cy7c68013 hangs computer

Good day everyone!

I have a problem with CY7C68013. Before, I was able to program and use this chip. When I got a new different chip for a new different project, I had a problem with the drivers because the new project uses different driver. CY7C68013 can be detected on the computer but my software cannot detect it anymore (software runs okay before i got this problem). I tried to uninstall and reinstall it but i got the same problem. Then I downloaded again the vend_ax.hex but ezusb cannot detect the device. What does this mean?

I tried to configure it by starting to the first step on how to use the project (my project comes with pld). I downloaded the right PLD file and it downloaded just right. Then I downloaded .iic, my computer hangs. I cannot even move my mouse. Why does this happen? Then I setup the project to use the CY7C68013, then USB Device not recognized pops up. VID/PID enumarates 0000. How can I get back to USB detection?

Your quick response is highly appreciated. Thanks

Step one is to get the VID/PID correct.

Sometimes there is a serial NVRAM that sets the VID/PID on the FX2. If this is missing or wrong, you will get the symptoms you describe.

Hi!

Thank you for your response.

How to set the VID/PID? The EZUSB Software cannot detect the device "No Cypress USB devices detected".

"Sometimes there is a serial NVRAM that sets the VID/PID on the FX2."

This is something you need to figure out and fix. You have not provided enough data for any one else to do it.
