Hi all, I programmed the OZY I2C EEPROM with a C0 load using the Cypress CyConsole EZ-USB program with: VID=0xFFFE PID=0x0007 Temporarily I have added the above VID/PID to the cyusb.inf file which will cause the generic CyUSB.sys driver to be loaded. Later I will switch over to the LibUSB-Win32 driver. 73 de Phil N8VB
