Hello,
It sounds like a problem with your custom hardware.
Also, VID_0000&PID_0002 doesn't match to what the FT905 is associated with.
What firmware is the FT905 running? Have you tried restoring the bootloader using the FT9xx Programming Utility found on your desktop as part of the FT9xx Toolchain (https://www.ftdichip.com/Firmware/FT90xToolchain.htm)?
Which silicon revision are you using? Rev B or the latest Rev C?
Please email your schematics to your local support team for review:
