Hello, yea I was just testing that today.. First problem was flashing the FW to V44 (I dont know what you mean with V47, i think the V44 is the last one) so as I said in that other post, thats the way how to update it. After that, be sure to reinstall the driver itselfs one again, reboot the PC and dont forget to reinstall the AI Suite 3 with version from Front Base support site.

Hopefully you will get it to work aswell.. If you need some more info, you can ask and I will try to help you.
