Hi ,I fail to load usb relative prx in PSP 2000 (3.60 M33), but it works well in PSP1000 3.52 M33-4 ,the error is SCE_KERNEL_ERROR_UNSUPPORTED_PRX_TYPE ( 0x80020148)
here's my code :
Code:
LoadStartModule("flash0:/kd/semawm.prx");
    LoadStartModule("flash0:/kd/usbstor.prx");
    LoadStartModule("flash0:/kd/usbstormgr.prx");
    LoadStartModule("flash0:/kd/usbstorms.prx");
    LoadStartModule("flash0:/kd/usbstorboot.prx");
and LoadStartModule function defined below:
Code:
int LoadStartModule(char *path)
   {
       u32 loadResult;
    u32 startResult;
       int status;

       loadResult = sceKernelLoadModule(path, 0, NULL);
       if (loadResult & 0x80000000)
      return -1;
       else
      startResult =
          sceKernelStartModule(loadResult, 0, NULL, &status, NULL);

       if (loadResult != startResult)
      return -2;
       return 0;
   }

I copy it from the ../sdk/samples/usb/storage.

I look forward to your help, thanks in advance.

Hi! :)

Sorry, I've not an answer to your question....just a question for you. :)

Are you sure this code works fine in kernel 3.52 (not 1.50)?
On my psp (3.52 M33) this code fails to load usbstorms.px and usbsotrboot.prx and the USB connection doesen't work.

I tried to use kubridge, but the prx loads fine but fails to start with
Code:
sceKernelStartModule(loadResult, 0, NULL, &status, NULL);

Maybe is due to some of the protection added by Sony in 3.40 or 3.30, that
prevented some uid's created by kernel mode to be accesed by user mode. But anyways the kuKernelLoadModule is working for me, soforget what i just said :)

With this code kuKernelLoadModule works for me (the module loads fine), but it fails to start (it happens only with usbstorms.prx and usbstorboot.prx).
I get a SCE_KERNEL_ERROR_LIBRARY_NOTFOUND error.
If I just copy this two prx from my flash0 to the ms, then pspSdkLoadStartModule works fine.
I'm on 3.52 M33-4, have you any idea?

Code:
int LoadStartModule(char *path)
{
    u32 loadResult;
    u32 startResult;
    int status;

    pspDebugScreenPrintf("Loading %s\n", path);
    loadResult = kuKernelLoadModule(path, 0, NULL);
    if (loadResult & 0x80000000){
       pspDebugScreenPrintf("kuKernelLoadModule: %x\n", loadResult);
       return -1;
    }else{
       pspDebugScreenPrintf("  Load OK\n");
       startResult = sceKernelStartModule(loadResult, 0, NULL, &status, NULL);
    }

    if (loadResult != startResult){
       pspDebugScreenPrintf("  Error starting module: %x\n", startResult);
       return -2;
    }
    pspDebugScreenPrintf("  Start OK\n");
    return 0;
}

//Init USB:
int USBinit(){
   u32 retVal;
    //start necessary drivers
    LoadStartModule("flash0:/kd/semawm.prx");
    LoadStartModule("flash0:/kd/usbstor.prx");
    LoadStartModule("flash0:/kd/usbstormgr.prx");
    LoadStartModule("flash0:/kd/usbstorms.prx");
    LoadStartModule("flash0:/kd/usbstorboot.prx");

    //setup USB drivers
    retVal = sceUsbStart(PSP_USBBUS_DRIVERNAME, 0, 0);
    if (retVal != 0) {
        pspDebugScreenPrintf("sceUsbStart BUS error: %x\n", retVal);
        return -6;
    }
    retVal = sceUsbStart(PSP_USBSTOR_DRIVERNAME, 0, 0);
    if (retVal != 0) {
        pspDebugScreenPrintf("sceUsbStart STOR error: %x\n", retVal);
        return -7;
   }
    retVal = sceUsbstorBootSetCapacity(0x800000);
    if (retVal != 0) {
        pspDebugScreenPrintf("sceUsbstorBootSetCapacity error: %x\n", retVal);
      return -8;
   }
   return 0;
}


Many thanks. :)

Try to load flash0:/kd/npdrm.prx before the other modules.
If npdrm loading fails too, load flash0:/kd/mgr.prx before.

One of the usb modules depend of npdrm. It is for the (useless) drm shit between the ps3 and the psp it needs that prx.

Yeah I know whenever you are gonna load a module from flash, always use kuKernelLoadModule.

Many thanks, half the problem is gone. :)

I loaded and started npdrm.prx as the first module.
Now usbstorboot.prx loads and starts fine, but.... usbstorms.prx starts but fails to load (always with SCE_KERNEL_ERROR_LIBRARY_NOTFOUND).
I also tried to load mgr.prx (also if npdrm.prx loads fine without it), but I get the same error.

Are there other dependencies to satisfy?
Is there a way I can know a module dependencies?

Many thanks for help :)

usbstorms has a dependancy on chkreg.prx, so you will need to load that first.

Taking a look at the module imports in prxtool and seeing which modules are required is the normal way and then compare that to what are currently loaded.

the problem doesn't gone, it's still there.
Code:
LoadStartModule("flash0:/kd/npdrm.prx");
  LoadStartModule("flash0:/kd/semawm.prx");
  LoadStartModule("flash0:/kd/usbstor.prx");
  LoadStartModule("flash0:/kd/usbstormgr.prx");
  LoadStartModule("flash0:/kd/usbstorms.prx");
  LoadStartModule("flash0:/kd/usbstorboot.prx");


any suggestion?

As cswindle said (many thanks!!!), usbstorms.prx depends from chkreg.prx

The following code works fine on 3.52 M33-4.
Code:
int LoadStartModule(char *path)
{
    u32 loadResult;
    u32 startResult;
    int status;

    loadResult = kuKernelLoadModule(path, 0, NULL);
    if (loadResult & 0x80000000){
       return -1;
    }else{
       startResult = sceKernelStartModule(loadResult, 0, NULL, &status, NULL);
    }

    if (loadResult != startResult){
       return -2;
    }
    return 0;
}

int USBinit(){
   u32 retVal;

    //start necessary drivers
    LoadStartModule("flash0:/kd/chkreg.prx");   
    LoadStartModule("flash0:/kd/npdrm.prx");
    LoadStartModule("flash0:/kd/semawm.prx");
    LoadStartModule("flash0:/kd/usbstor.prx");
    LoadStartModule("flash0:/kd/usbstormgr.prx");
    LoadStartModule("flash0:/kd/usbstorms.prx");
    LoadStartModule("flash0:/kd/usbstorboot.prx");

    //setup USB drivers
    retVal = sceUsbStart(PSP_USBBUS_DRIVERNAME, 0, 0);
    if (retVal != 0) {
      return -6;
    }
    retVal = sceUsbStart(PSP_USBSTOR_DRIVERNAME, 0, 0);
    if (retVal != 0) {
      return -7;
   }

    retVal = sceUsbstorBootSetCapacity(0x800000);
    if (retVal != 0) {
      return -8;
   }
    return 0;
}

int USBActivate(){
    sceUsbActivate(0x1c8);
    return 0;
}

int USBDeactivate(){
    sceUsbDeactivate(0x1c8);
    sceIoDevctl("fatms0:", 0x0240D81E, NULL, 0, NULL, 0 ); //Avoid corrupted files
    return 0;
}
