Ok, I was able to get the usb working on my little program. I used the example from the sdk. Anyways, I changed my code around a bit, and now it crashes whenever I load up the game. Here's the code I'm using.

Code:

#include <oslib/oslib.h>
#include "usb.h"

u32 state;
u32 retVal;

__attribute__ ((constructor))
void loaderInit()
{
pspKernelSetKernelPC();
pspSdkInstallNoDeviceCheckPatch();
pspDebugInstallKprintfHandler(NULL);
}

//helper function to make things easier
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;
}

void StartModules()
{
state = 0;
//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 starting USB Bus driver (0x%08X)\n", retVal);
sceKernelSleepThread();
}
retVal = sceUsbStart(PSP_USBSTOR_DRIVERNAME, 0, 0);
if (retVal != 0) {
printf("Error starting USB Mass Storage driver (0x%08X)\n",
   retVal);
sceKernelSleepThread();
}
retVal = sceUsbstorBootSetCapacity(0x800000);
if (retVal != 0) {
printf
   ("Error setting capacity with USB Mass Storage driver (0x%08X)\n",
   retVal);
sceKernelSleepThread();
}
retVal = 0;
}

void USB()
{
state = sceUsbGetState();
if (state & PSP_USB_CABLE_CONNECTED) {
   if (state & PSP_USB_ACTIVATED) {
      //I'll add image blitting later
   } else {
      retVal = sceUsbActivate(0x1c8);
   }
} else if (state & !PSP_USB_CABLE_CONNECTED) {
   if (state & !PSP_USB_ACTIVATED) {
      //do nothing!
   } else {
      retVal = sceUsbDeactivate(0x1c8);
   }
}
}

I use StartModules(); before my main loop(in my main file), and then USB(); inside of the main loop(also in my main file). I also use

Code:

PSP_MODULE_INFO("Blah", 0x1000, 1, 1);
PSP_MAIN_THREAD_ATTR(THREAD_ATTR_USER | THREAD_ATTR_VFPU);

in my main file.

If you need to see the whole source, I can give it to you, but I'm pretty sure there is something wrong with the usb.cpp file.

Another thing, Is there a quicker way of activating the usb, or is this the fastest way there is?
