This is the REAL problem -- the inexorable Prolific chipset and the vast number 
of counterfeit copies that the current "official" drivers brick.

You should INSIST on serial<-->USB cables based on the FTDI chipset which is 
stable, well-behaved and not plagued with official vs unofficial driver 
distributions.    As a bonus, the FTDI devices always take on the same COM 
number, no matter what USB port or hub you plug them into.  [There is something 
analogous to a unique MAC code in every FTDI chip that lets the driver 
positively identify a given device regardless of what port you plug it into.]

By contrast, the Prolific devices take on a DIFFERENT COM number every time you 
plug them into a different port, or into a hub vs direct connect.
