I'm working on custom firmware HAL for Nanodesktop.

So, when I try to use sceUsbStart, the homebrew is terminated
by the VSH with an error code 8002013C

The firmware is version 3.77 M33-4 on PSP-SLIM.

Why ?

The NIDs for USB functions have been changed ?

I trust you're not simply calling sceUsbStart();? :D

See the example in Cygwin\usr\local\pspdev\psp\sdk\samples\usb\storage (If you're using CYGWIN) on how to properly start USB.

Hi! :)

This works for me with kernel 3.71.

usb.c
Code:
#include <pspkernel.h>
#include <pspusb.h>
#include <pspusbstor.h>
#include <kubridge.h>

SceUID modules[7];

//Init USB:
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 StopUnloadModule(SceUID modID){
    int status;
    sceKernelStopModule(modID, 0, NULL, &status, NULL);
    sceKernelUnloadModule(modID);
    return 0;
}

int USBinit(){
   u32 retVal;

    //start necessary drivers
    modules[0] = LoadStartModule("flash0:/kd/chkreg.prx");
    modules[1] = LoadStartModule("flash0:/kd/npdrm.prx");
    modules[2] = LoadStartModule("flash0:/kd/semawm.prx");
    modules[3] = LoadStartModule("flash0:/kd/usbstor.prx");
    modules[4] = LoadStartModule("flash0:/kd/usbstormgr.prx");
    modules[5] = LoadStartModule("flash0:/kd/usbstorms.prx");
    modules[6] = 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;
}

int USBEnd(){
    int i;
   
    sceUsbStop(PSP_USBSTOR_DRIVERNAME, 0, 0);
    sceUsbStop(PSP_USBBUS_DRIVERNAME, 0, 0);
    for (i=0; i<7; i++){
        StopUnloadModule(modules[i]);
    }
    return 0;
}


usb.h
Code:
int USBinit();
int USBActivate();
int USBDeactivate();
int USBEnd();


Ciaooo
