Thanks for the feedback Sananya! I'll try it on Monday. I'm a bit skeptical because it only mentions the CY7C68103A ... and I'm pretty sure the "No EPROM" USB response are the same for the CY7C68013 and the "A" part.
As you mentioned, there is no difference with respect to No EEPROM USB boot mode between the two and the .inf file includes the default VID/PID which is the same for both the parts. You could also download the driver package from the KBA, the version should be same as that in the other KBA for Windows XP.
Please use the driver files attached to this response for Win XP and Vista. You will have to manually bind the device to this driver once in Win XP and Vista.
This is the latest certified driver for XP/Vista and has been tested.
