Disassembling USB-Mod, to solder the chip inside ?

[Omega-3]

I want to disassemble my USB-Mod because it sucks. I have never been able to boot any copy, instead of PSX´s. Now I want to know if anybody may help me with the description of the Chip in my USB-Mod: 12c508a, 04/P82J, 0118
Thats it. Is this a Neo2 or a Neo2.2 ?
And if I take it out of the USB-Mod, do I have to (I think so) connect any capacitor to my PS2-Motherboard ? And which type of Capacitor do I need ?
My PS2 is PAL, SCPH30004, 8-screwed, should be V4.

Please post some ideas if this is worth a try.

thx
