I had an odd thing happen with my script.
I have two cameras set up - a 7D & a T2i - both referenced correctly in the script. When I run the script, the 7D works just fine (although it does seem to drop a frame or two after a series of successive exposures separated by one sec, even with a 600x card). The T2i doesn't work at all. I get a burp from the computer when the exposure is initiated and the log says "script camera not recognized".
When I try the T2i on it's own with the same script, it works just fine.
Not quite sure what the problem is. Slow USB ports? Bad cable (although it works on it's own with the same cable). Something else?
