[NEED DEVELOPERS]Demo with USBPSPCMDriver(2nd Release)

[173210]

USBPSPCommunicationDriver is used to connect PSP with PS2/PS3.
It works on ePSP, too.
I disassembled two games which use USBPSPCommunicationDriver.
And I found how it start.
How it start:
1. load flash0:/kd/usbpspcm.prx
2. call sceUsbStart(PSP_USBBUS_DRIVERNAME, 0, 0);
3. call sceUsbStart("USBPSPCommunicationDriver", TITLE_LEN, TITLE);
4. call sceUsbActivate(0x1CB);

I wrote this code with the information, and it worked.
Test it and report!
2nd Release:

----CheangeLog----
2nd Release : Added exit code.
Added disconnect detect thread.

----For Developer----
I need PS2/PS3 Developers.
To connect with PC by this driver, we must understand how it works on PS2/PS3, too.
So I want PS2/PS3 Developers to reverse these games.

We must reverse PS2/PS3 games to do it.

Unfortunately I haven't finished learning enough of ASM (MIPS) to be remotely helpful. But this seems to have a lot of potential! I can help by making a blog post if/when you get this to work.

Wow, now this is awesome. I know this is in early stages, but still, this is awesome.

I am no dev, but I do offer you all my luck.

And if you need any pc testers, on Windows or Linux, I would be happy to help. At least once it gets to that stage.

for ps2 you just need to reverse usbd.irx, found in some games that use the usb ports
