Due to Amtel usb chip is expensive and hard to buy, let's dance with cypress
ezusb fx2lp.

fx2lp is widely used USB2.0 high speed chip over the world, and it is 8051 core, most of mcu engineer are familiar with 8051, so take it easy.

I've already calc the total size of descriptors, is 6809 bytes, with about less than 4kb codes, it can fit in fl2lp 16KB ram (a 16K eeprom is needed to store the fw). so this plan is doable. (total cost may less than 20$)

current NO code commited, this project is in a PLAN stage. but I've already do some work on it. and a problem is my PS3 is 3.10fw, because I want keep linux. so I really can't debug it on my machine now. when phiren release 3.1x psgroove, I'll complete this project immediately.

it seems the FX2 is fixed, so not possible to be port to.
