These instructions work on WindowsXP SP2/Vista with the EZ-USB Control Panel (EZ-USB_DEVTOOLS...zip, ~61 megs) (that link may be broken in the future, but it's probably still named something similar on cypress's website if you look here.

  1. Plug the device in with EEPROM activated (jumper not connected).
  2. Using the plug and play wizard, install the ezusb.sys drivers (if not done already).
  3. Device Manager should recognize it as:
    Cypress EZ-USB FX2 (68613) - EEPROM missing
  4. Connect jumper
  5. Open up the EZ-USB Control Panel.
  6. Click on the EEPROM button.
  7. Choose the fw_async_ifclk.iic file (local copy)
  8. Unplug the device and plug it back in. Device Manager should now see:
    Cypress EZ-USB IDLAB-STD
  9. At this point it may be required to install the ezusb.sys again.
