Does the adapter work with Windows Vista or Win 7/8?
Yes, it works with all versions of 32-bit Windows Vista and Windows 7/8.  During the installation process the latest driver is updated  from Windows Update. You don't even need to insert the CD-ROM - Windows gets what it needs from Windows Update. 

In March of 2009, Prolific released a driver for the 64-bit editions of Windows Vista.

In December of 2009, Prolific released a driver for the 64-bit editions of Windows 7.

Note that the the 64-bit drivers are not available from Windows Update and must be downloaded and installed separately.

Does the adapter work under Linux?
The driver disk includes drivers for Red Hat Linux 7.3, 8 & 9
Does the adapter work with Macs?
The driver disk includes drivers for
Apple Macintosh IMAC 8.6,9.0 & 10.0
Can I use the adapter in reverse to plug USB devices into a serial port?No, the adapter cannot be used for plugging USB devices into a serial port.
Does your adapter work on every computer?
In our experience the adapter works on a majority of hardware for the supported operating systems. There are cases where the adapter will not work with the existing hardware or software.
What if my serial device has a male connector (with pins)?
Our adapter ships with a 9-pin male plug. This is the same connector found on the back of computers with a serial port. If your serial device also has a male plug then you need to obtain a 9-pin gender changer. This is a double ended female to female connector that will allow you to plug your device into the adapter. 

Gender changers are available from Beagle Hardware.
