Hi! :)

I'm experiencing problems enabling the usb in a kernel 3.52 app.
First I had problem loading the usbstorms.prx (with the code from the sdk's sample) and I fixed it using pspSdkLoadStartModule.

Now is the last prx that fails to load (giving error 800213C) usbstorboot.prx
This way it fails also the sceUsbstorBootSetCapacity() call.
When I call sceUsbActivate() Windows detects the new hardware but I cannot see the new drive...

Here's my code:
Code:
//Init USB:
int USBinit(){
   u32 retVal;

    //start necessary drivers
    pspSdkLoadStartModule("flash0:/kd/semawm.prx", PSP_MEMORY_PARTITION_KERNEL);
    pspSdkLoadStartModule("flash0:/kd/usbstor.prx", PSP_MEMORY_PARTITION_KERNEL);
    pspSdkLoadStartModule("flash0:/kd/usbstormgr.prx", PSP_MEMORY_PARTITION_KERNEL);
    pspSdkLoadStartModule("flash0:/kd/usbstorms.prx", PSP_MEMORY_PARTITION_KERNEL);
    pspSdkLoadStartModule("flash0:/kd/usbstorboot.prx", PSP_MEMORY_PARTITION_KERNEL);

    //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;
}


Can someone help me loading this module, please? :)

P.S. If I copy the prx from my flash0 to my ms, then the module starts correctly...

Many thanks.
Ciaooo

Sorry, I can't understand what you're saying here.
What's the problem with a int function returning -6 or -7?

i dont know...

but i have allways
Code:
return -1
...
have you this code in your app?

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;

}

??

when not, try it out...

---
and my code for this is:
Code:

//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) {

        printf("Error.... (0x%08X)\n", retVal);

        sceKernelSleepThread();

    }

    retVal = sceUsbStart(PSP_USBSTOR_DRIVERNAME, 0, 0);

    if (retVal != 0) {

        printf("Error.... (0x%08X)\n",

               retVal);

        sceKernelSleepThread();

    }

    retVal = sceUsbstorBootSetCapacity(0x800000);

    if (retVal != 0) {

        printf

            ("Error... (0x%08X)\n",

             retVal);

        sceKernelSleepThread();

    }

    retVal = 0;


i hope it help
