USB to Serial Adapter Installation

[dowdenjn]

I just purchased a usb to serial adapter in order to use a windows
program requiring a serial port for data access. Under the usb
settings for windows xp professional I see a usb fast serial adaptor
button when I connect the adapter to my mac powerbook G4. However,
when I select the box the setting is not saved thus the usb adapter is
not made available to me. Does anyone know how I might work around
this problem or find a more workable way to install a serial port to my
MAC for access through Virutal PC 7?

thanks.
