I have designed a PCB for Cy7C65211 IC. In datasheet the default VID & PID is given and after connecting it to the PC the system throws error as "Device Descriptor Request failed" in the device manager. I tried to change the *.inf file, but need further assistance.
- The problem could be possibly due to improper layout, do recheck that.
- Could you send a screenshot of the error message in the Device manager?
- Why are you trying to modify the *.inf file? If you are using the default VID,PID of Cypress, you need not modify it.
