How can I make the USB connect to the flash0 or flash1 instead of the ms0?

I have tried this:

Code:
   sceIoUnassign("ms0:");
   sceIoAssign("flash0:", "lflash0:0,0", "flashfat0:", IOASSIGN_RDWR, NULL, 0);


but that doesn't seem to do anything... I know I'm missing something but I've completely forgotten what it is.

I do. I wanted to be able to access my flash drives through an eboot program so I could modify the files.

not exactly copy it, but use it in a different program.

the only problem with that code is that on the assign the mention of the device needs to be "ms0:"
Code:
sceIoAssign("ms0:", "lflash0:0,0", "fatms0:", IOASSIGN_RDWR, NULL, 0);


before you were just reassigning flash0, probably returning an error code because it was already mounted. I also put in a change in the map for the block device, which may also be nessicary (or not).

Now you just have to start up the usb mass storage drivers

ooohhhh... so shouldn't this work? It didn't work when I tried to compile it in the complete program. Well, it compiled but when I ran it on the PSP it connected to the ms0 instead of the flash0. Should I remove sceIoUnassign() or the "fatms0:" part? (I have a gut feeling it's one of those two)

Code:
void start_usbf0()
{
   sceIoUnassign("ms0:");
   sceIoAssign("ms0:", "lflash0:0,0", "fatms0:", IOASSIGN_RDWR, NULL, 0);

   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);

   sceUsbStart(PSP_USBBUS_DRIVERNAME, 0, 0);
   sceUsbStart(PSP_USBSTOR_DRIVERNAME, 0, 0);
   sceUsbstorBootSetCapacity(0x800000);

   sceUsbActivate(0x1c8);

   usbStarted = 1;
   printf("\nUSB activated\n");
}

To assign flash0:/ to usb you need to create a new driver for it using the sceIoDrv functions. Theres an example of this in the mph fw launcher source.

It is more complicated that simple assign/unassign.

You have to redirect the msstor driver functions to the lflash driver functions, and handle some msstor specific ioctl codes (0x02125008, 0x02125803) and devctl codes (0x02125801).

Not yet, the driver functions from MPHL's firmware launcher code are a bit confusing.

Don't worry, I'm still working it on it.
