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.
