Is it possible to reprogram or erase the external EEPROM connected to the CY7C65630 after it has been initially programmed? Looking at the datasheet, it looks like once the EEPROM is successfully programmed and power cycled, the hub will no longer enumerate as a vendor class device. Does this mean that the EEPROM can no longer be erased or reprogrammed?

Hello,
The EEPROM can be reprogrammed by binding the hub to the vendor driver.
- From the device manager, right click on the device and choose 'Update Driver'.
- Then, choose 'Browse my computer for driver software'.
- Choose, 'Let me pick from a list of available drivers on my computer'.
- Click on 'Have Disk'.
- Point to the INF file in the attachment.
The device now gets bounded to the vendor driver and the Blaster tool can be used to reprogram the EEPROM.
