Good drivers allow you to set which COM port the driver attaches the USB 
virtual device to.  If you get an adapter that doesn't allow it, send it 
back.

A large quantity of the USB to serial adapters are using the FTDI 
chipsets.  http://www.ftdichip.com/

They have royalty-free drivers on their website for use with their 
chipsets for those who like to roll-their-own interfaces.

See http://www.ftdichip.com/FTDrivers.htm for explanations of the 
different types of USB to Serial drivers.
