I assume the USB->Serial converter has a male conector on it. Is that correct?

What kind of connector is on the BrailleNote?

Didn't the BrailleNote come with a serial cable?

Exactly as expected if it's now on ttyUSB0.

This (a timeout, i.e. no response) could easily be a serial cable mismatch 
problem.
