i download the CYStream_RefDesign file,and use the CyUSB.inf,when i install the inf file,it remind me error code 10.now am confuse.
Choose .inf file for your OS from cypress directory and modify it for your device (change VID PID). Put both files, .inf and CyUSB.SYS in same folder. Now in device manager try update driver and point it to the folder containing both file. For more details see CyUSB.pdf in C:\Cypress\Cypress Suite USB 3.4.7\Driver.
i did't use eeprom,should i change my vid and pid? thanks
Go through CyUSB.pdf in C:\Cypress\Cypress Suite USB 3.4.7\Driver.
