It's for compatibility with Linux - Myth doesn't care.

Have you tried temporarily swapping one of the USB->Serial converters 
from your known working D10s to the H23?  Or try the converter your are 
trying to use on your H23 with one of your D10s?

My guess is your converters/cables are fine and the USB port on your H23 
is probably flaky.
