Glad you got it working!

It sounds to me like you got bit by the Prolific drivers and possibly
counterfeit Prolific chips (seems to be about 90% of the topics on
this mailing list). Considering both your Kawamall cables exhibited
the same symptoms, I doubt it was a manufacturing anomaly.

FWIW, I buy the serial version of cables for all my radios. This way I
can use my proven FTDI USB-serial cable with all of them. Having just
one type of USB cable means I only need one driver (serial cables
don't need drivers). This means I don't have to mess with drivers when
I buy a new cable.
