No need.

and i tried to modify the gui live.lua you wrote for "onion" to get the function i need,but looks not working  because i can not run the CHDK PTP
If there is an error in a lua file, an error message should be printed somewhere. If you start chdkptp from the command prompt, you are more likely to see error messages early in startup.

Hi,reyalp：
   i just found this pagehttp://chdk.wikia.com/wiki/Script_commands_stub and i noticed that on the “List of buttons that can be used:” do not include all the functions which a normal camera  has,like video、 wheel-L and wheel-R.is that possible to add these functions？

That's a very old, incomplete page. For script information, I would start with http://chdk.wikia.com/wiki/CHDK_Scripting_Cross_Reference_Page

To know which keys are supported on a given camera, you probably have to look at the CHDK source. kbd.c for your camera is
https://www.assembla.com/spaces/chdk/subversion/source/HEAD/trunk/platform/sx170is/kbd.c

You should be able to control the wheel with the wheel_left and wheel_right functions.

If there are keys which are present on the camera, but not supported in the port, you can probably use levent functions http://chdk.wikia.com/wiki/Lua/Lua_Reference/Levent

Hi,reyalp;
FWIW, I am not an expert on the USB remote code.

If the camera responds to the remote, that probably means the hardware is working.

I would suggest
1) observe the camera more closely to see exactly what it's doing. The Canon firmware can refuse to shoot in some cases, for example if you are in auto mode and it doesn't think the focus is right. There should be some sign in the UI if this is happening. You can also try shooting in exactly the same conditions using the shutter button instead of the remote.
2) Post exactly which remote settings you are using.

If you post what was wrong, it may help others who encounter the same problem in the future.

kbd.c is part of the CHDK source. Each port has one in its platform directory.

If you are wanting to mix USB remote and PTP, CHDK 1.4 now includes the usb_force_active (http://chdk.wikia.com/wiki/Lua/PTP_Scripting#usb_force_active) function for almost all ports.
