EB100 Needed Information

There are still many unanswered questions about the EB-100 and siblings' hardware. The information we have is sufficient for a basic support, but many features are probably handled in a wrong way and other doesn't work at all. Anyone who can and is willing to help is encouraged to contact us or just fill in what he/she knows here. I'm afraid that answers are mostly 'no'. Sorted by (subjective) importance.

• Is there a JTAG interface somewhere?
• Is it possible to use the USB gadget controller? If yes, how?
  • Can be the gadget controller used at the same time as the host controller connected to the USB storage part?
  • Is it possible to change the port used for the USB storage?
• How to connect an internal device to the second USB port? How to enable it?
• Are there any GPIOs that are accessible and free for GPIO use?
• Is the second/thrid UART connected to an accessible place?
• Is it possible to use the second USB host port to connect external devices through the USB connector? What is the correct procedure to enable it?
