You're mis-understanding regular expressions.

This regex will match ttyUSB0000, ttyUSB20, and ttyUSB522343234.

Which is why when you include the "1" you match ttyUSB10, ttyUSB10, 
ttyUSB11, and ttyUSB12.  If this is matching ttyUSB9 then I would guess 
there is a bug in hylafax. To match ttyUSB1 and not ttyUSB10 you need to 
put "outnow:ttyUSB[0-5]$".  The dollar sign means thats the end of the 
string.

And thats not a regex.  Thats file globbing in you sheel.  Regex will 
match substrings, while file globbing only matches complete strings.  If 
it was a regex you'd also match config.ttyUSB02342, config.ttyUSB12, 
config.ttyUSB8232423, etc.

I can't test modemgroup regex's here so I can't add more than that 
explaination.
