patch exedsp workshop

Post by ocean » Tue Aug 27, 2013 7:43 am

As I'm getting a little irritated by the "new usb device connected" message with my nfs_mount_script (viewtopic.php?f=52&p=44745#p44745)
I'm looking for a solution to patch exedsp to ignore new devices so that this message won't appear anymore.
I hope one of our crew is able to show me and all other users who are interested in this project, HOW-TO-PATCH exedsp.

Kind regards

Okey, here we go:

Patch for D series arm (T-GAS*DEUC):

Code: Select all

{ "_ZN7CUSBApp8OnActiveEl",	0x00000000,	0x00000080,	0x00000100,	0xEB000922, 0xE1A00000, NULL }, //New device POP UP OFF
Patch prohibits popup message "new device connected" if any USB device is connected (checked with USB and wifi dongle).

Code: Select all

./memjack -p `pidof exeDSP` -d
pc=41cdb670 lr=41cdb65c sp=bef9c088 fp=59a0024
r0=fffffe00 r1=80
r2=1 r3=0
symbol: _ZN7CUSBApp8OnActiveEl -> @0x0229e5dc
patching @229e5dc + 84: eb000922 -> e1a00000
library injection completed!
Try to check same on E series.
Thanks to rvs2 :)

Code: Select all

_ZN12CUSBPopupWnd4ShowEv

_ZN18CUSBAppListWrapper14SubscribeEventEi
_ZN18CUSBAppListWrapper11IsUSBDeviceEi
_ZN18CUSBAppListWrapper15IsDeviceConnectEi
