but it doesn't see my new Gekkoscience Compac A1s. Does this cgminer build not have support for them?
Correct.
It probably does not support the Compac-F either as the drivers for both were added by Kano just a few years ago for the F and last year for the A1.
Link to Kano's git is in my sig.
btw: that version of cgminer you have is a hacked version and NOT recommended. Amongst other things it adds an extra nonce aka the Golden Nonce. That is a security risk as it allows the miner to switch work to mining other coins without telling you about it...
Great, thanks for the info! Had no idea I was able to install Kano's version but now I'm getting an error when I run it:
