| Code: | d3744be0,module_bootstart
f01d73a7,module_info
2f064fa6,module_reboot_before
d632acdb,module_start
0f7c276c,module_start_thread_parameter
cee8593c,module_stop
cf0cc697,module_stop_thread_parameter |
A modified nidattack came handy ;)
Only one missing from the range of syslib exports:
| Code: | sceModuleManager
FUNC - NID adf12745 - ENTRY 8805cecc - NAME ?? |

| laichung, if you saw this one while working on usbacc.prx.... a logical guess would be that this entry point is called before rebooting the PSP in order to (possibly) reset the attached USB devices? |

usbacc.prx doesnt have "module_reboot_before" but usb.prx does. From the view of source, I only know this function stop the USB Bus Driver and call UsbDeactivate. And anyone know which function will call first when PSP reboot? stop or reboot? What happen if we unload the usb.prx? (I cant test it since I dont have a serial connect)
More information about usbacc.prx, it is a USB accessory base driver and usbmic call some functions from it to init/register the device. But my guess is , usbacc only register the device and allocate some FPL for the device. The low level function of the USB still inside usb.prx
Also from the 2.8 usb.prx, some new and unknow functions are added. And those function called sceGpio and print contain some error message like : "usbbd ERROR : cannot setup GPIO for USB host power supply : 0x%08x"
I have to say, it doesnt mean PSP has a USBHost/USBOTG (please, no more discuss in usbOTG , thanks everyone) , but possible to emulate some basic functions (power,Endpoint,get descriptor, etc) as a host.
Thanks
