Likely an oversight on my part two+ years ago but easy to fix.
I rebuilt a CHDK 1.0.0 release for my ixus120 and tested your script fragment.  It turns out that wait_click(0) would also not wake up on a USB remote key press on the USB remote code prior to  2.0.  So the bug is not new.

In any case,  I've attached a patch file for 1.3.0.   Works on my A1200 and so should be good for everything.  Please test and if it works correctly for you as well I'll do one for 1.2.0 to go with it.

It works fine, a small problem less, thanks.

I have tried this variant the first time for an alternative script solution.

The commercial remote Ricoh CA-1 has been discontinued a while back it seems and is no longer for sale as a new item. They now have a CA-2 which has a different USB connector. Has anyone tried this CA-2 with an according adaptor yet? Somewhere I read that the CA-1 with an adaptor doesn't work on the newer Ricoh cameras but I don't know if that information is accurate.

A brief session of googling did not turn up any detailed info about the CA-2. However the posted images look identical to the CA-1 except for the connector.  If anyone has better info I would be very interested.

Update : James at gentles confirms that the only difference between the CA-1 and CA-2 is the size of the USB connector. So the existing CHDK code will work if you built a cable adapter.

Ah excellent. Thank you. I don't know about building. I'll see if an adapter from the one USB type to the other exists on ebay or do you suppose that I'd actually have to re-wire it in a way beyond a simple adaptor? I guess you know this one but since it is the only bookmark worthy link I came across while researching this I'll include it anyway: http://stereo.jpn.org/eng/sdm/ca1.htm

Edit: I think I can forget about an ebay obtained adaptor:
Connectivity. Ports on the Ricoh GR include a combined USB 2.0 High Speed and NTSC / PAL-compatible standard-definition audio/video connector [...] The combined USB / AV port, meanwhile, is also compatible with Ricoh's CA-2 cable release.
From: http://www.imaging-resource.com/PRODS/ricoh-gr/ricoh-grA.HTM

CA-2 looks like a proprietary cable solution to me.

Well,  it's at least a proprietary connector.  But there are most likely only two conductors that connect from the plug to the CA-2 body (based on how the CA-1 works).   

So you could just cut off the proprietary plug and splice it to 1/2 of a standard USB cable.  You just strip and twist the two wires together and tape them up, or use a couple of small "wire nuts / marr connectors".  No soldering required.  I could do the whole job with a pair of kitchen scissors and a small roll of black electrical tape.

You're right. I just disliked breaking the thing. I'll see if a CA-1 crops up on the used market. If it doesn't I'll do what we discussed here to a CA-2. Testing all those cams for their USB Remote feature compatibility made me think - hey I need a USB remote... But it's really not urgent.

I bought a CA-1 when I was rewriting the USB remote code in CHDK from scratch.  Can't say that I've used it much since then - the button is cheap and a bit touchy and the cable length pretty short.   If you are at all handy,  a "home brew" is pretty easy to put together :

Otherwise,  I believe these gentleman are still in business :

These very neat switches are my favourite, and not just because I was given a development sample :-
