CY4500 software error

[abc4329803]

And I have purchased CY4500, and installed the latest software (name: ezpdprotocolanalyzer_3.1.0_Windows_x86-x64.exe) on Win7 and Win10. After installing the driver,  there is a tip for these two computers which tells me that 'Unable to scan for USB devices: javax.usb.UsbPlatformException: USB error 99: Unable to get USB device list:'. I also see Cypress ED-PD Analyzer is in  the libusb-win32 devices from the device manager. That means I had sucessfully installed usb driver. I also reboot these two computers, but problems still occurred.

Hi,

Can you please specify the version of Java that is installed in the PCs?

[abc4329803]

java verion "1.8.0_311" in Win 7

java verion "1.8.0_281" in Win 10

Hi,

This error seems to be specific to Java. Can you please try reinstalling the same and check if it works?

[abc4329803]

Yes, I uninstalled all the JAVA and reinstalled again. The new java version is java verion "1.8.0_311" in Win 7. But  the same error still happens.

I try CY4500 on the third computer, which is installed by Win10. But another error happens: utility asks me to upgrade the firmware, but the firmware tool could not find the hardware. Please see the attachment.

Hi,

I think the hardware is not bound to proper driver. That is the reason why it cant update firmware. 

Please install the following software which also installs the correct driver necessary. - https://www.infineon.com/cms/en/design-support/tools/configuration/usb-ez-pd-configuration-utility/

Also in Device Configurator make sure you have right driver bound to the CY4500 hardware.
