Any chance you share the source of the test program?
You can reverse engineer it :lol:

Lol thxs...missed the src cause I didn't decompress it when tested for first time.
Mine's finally working tho... but it will be good to compare both.

Looking at source code:
#define PSP_USBPSPCM_REGISTER 0x03415001

google hit shows SceIoDevCtl 'Register USB thread'
But how did you find about that number??

@abdou005 It is expected to fail in Vita.

It's a shame that this is dead. :o

USBPSPComm has been with the PSP for a very very long time, since 2004. It was originally going to be using the PS2 as a relay station, while two PSPs would connect directly to each other. But most game developers ended up using the PS2-PSP connectivity options to transfer/unlock features. There's also a "title check" string that's needed with the prx, which is also needed for the other end as well. :mrgreen:

I know I'm a bit late, but what does (or did) this do? I've read the Op and still have no clue :/

As you probably know, ePSP has no access to USB and the functions are dummied out, however, there are some games that do psp <-> ps2 / ps3 communication to transfer data and this does work, sooo we want to somehow abuse it and use USB the regular way

Resistance Retribution has a very detailed usb connection with ps3. it can get dualshock 3 buttons through ps3, enable some extra modes etc. rumble, second analog and extra triggers on ds3 work too. http://www.ign.com/articles/2008/11/13/ ... mpressions
