I have two A480 cameras attached to the computer, running chdk. when i execute 'rec' one camera goes into record mode.
If you are using multicam, you should not use regular chdkptp commands or GUI controls.

Then I input the multicam code you provided... and nothing seems to happen. it goes on from there. I'm sure you can read the code in the screenshot better than I can explain it here.
You did not use the mc:start() line after connect, so the camera side script is not running. That's what the "script not running" in the output is telling you.

Also, I notice that the connection dropdown at the top right of chdkptp will display nothing if both cameras are connected when I open the program.
As I said earlier

The normal GUI controls are only set up to work with one camera, so wont be very useful and may break with multicam
I would personally stick to the CLI (starting chdkptp with chdkptp.exe -i) for this kind of thing, but IIRC andrew.stephens uses the GUI (edit: oops, my mistake: https://chdk.setepontos.com/index.php?topic=12368.msg134393#msg134393).

Ok I think I'm starting to get this more and more. But one thing confuses me. You've said "You can run chdkptp in cli only mode by starting with -i"

and

"I would personally stick to the CLI (starting chdkptp with chdkptp.exe -i) for this kind of thing"

But I have no idea how to start chdkptp like that. As far as I can see, in my newb eyes, there is an application called chdkptp, I double click it, and it automatically opens the program CHDK PTP. There is a black CLI window in the background that says "starting gui" but I can't seem to input anything into that. So I have no idea how to start chdkptp in CLI only mode.   Screenshots below.

reyalp is talking about using what Windows calls the Command Prompt window to manually type in commands.   You might be able to find it in the Accessories folder when you select All Programs in the Start Menu.

If this is confusing to you, I'll see if I can find an online tutorial to get you started.

Thank you Waterwingz. I've found Command Prompt and have been using the guide link you sent to figure it out. Huge help! :-)

The CLI is actually pretty easy with that guide. But now I run into a wall again. I get to the folder chdkptp is located in, and I can start up chdkptp GUI from the Windows Command Promt, but I can't seem to start chdkptp in it's CLI form from the Windows Command Prompt. See Screen Shot.

You got the order wrong.

chdkptp -i

ah! that figures :-)

Success! Writing "chdkptp -i" worked for starting the program in CLI in Windows Command Prompt.

I followed the steps reyalp mentioned in reply #6. But nothing happens in the cameras. I tried this with the cameras in both regular mode, and in ALT mode, just in case. Both seemed to have no effect on the cameras.

mc:connect()  reports each camera it connects to, with a line like:
Code: [Select]
+ 1:Canon PowerShot SX160 IS b=\\.\libusb0-0001--0x04a9-0x325a d=bus-0 ....

Since it produced no output for you, that means chdkptp didn't see your cameras at all.
If you enabled "USB remote" on your cameras, make sure it's turned off.

You can copy and paste text from the command prompt window rather than posting screenshots.
Don't forget what the H stands for.

hmmm... strange that it does not detect a camera. I hear the Windows chime that the usb device (camera) has been connected, then I start up the chdkptp cli. I've tried this a few times, and it seems I have to wait a minute or so, then I can run !mc:require'multicam', and !mc:connect, and it detects one of the two cameras, but not both.

As for the settings on the cameras, under Remote Parameters, I have the following settings:
Enable Remote - NOT ENABLED (no little dot)
Switch Type - OnePush
Control Mode - Normal
Enable Synch - Enabled (little dot is on)

Perhaps a list of my steps so far would be helpful. Maybe I am doing something wrong, or not doing something I should be. I hope this helps :-) Also, I am running on Windows 10 Home 64-bit, if that makes any difference.
----
Download and Install the correct version of CHDK on the SD memory card for my A480 cameras.

Install CHDK on Camera.

Plug In Camera to Computer

Run Zadig, install LibUSB-win32 on Camera

Unplug and restart Camera.

Re-Update/Install CHDK on Camera from SD memory card

Plug camera into computer

Start Windows Command Prompt

Run CHDKPTP CLI (chdkptp -i)

Follow steps provided in reply #6
----

Upon running more trial and error tests (switching usb cables, etc), I've found that the only camera the chdkptp finds is the one that is most recently updated with LibUSB-win32.

The zadig libusb install is probably only valid for the specific physical camera. In that case, that step needs to be repeated for each camera.

I'm not sure what you mean here, but you do not need to re-install CHDK after installing the libusb driver.
