appreciated.
I updated the block diagram: http://rhombus-tech.net/community_ideas/games_console/news/pcb_block_diagram...
Anything more to change?
yes, one thing that's important: 1st USB is mandated to be >= speed than 2nd USB. so you need to swap 1st USB with 2nd USB.
reason: the STM32F is connected to the port that may end up being 480mbit/sec and the USB Hub is connected to the port that may end up being only 11mbit/sec.
certainly, for the jz4775 CPU Card (which i am sending off very shortly), it *DEFINITELY* has USB 2.0 for the 1st port and *ONLY* USB 1.1 for the 2nd.
and i am certainly not going to increase the cost of the jz4775 CPU Card by an extra $2 worth of components to put in a USB2 Hub when the SOC itself is only $2.50!!!
I think that you have not properly seen the block diagram.
The STM32 is connected to the second USB, the USB HUB is connected to the first USB.
This right?
