Windows Drivers
Windows XP, Windows Server 2003 and Windows 2000 are supported with a single driver that
works as a combined driver model (CDM). It will expose a COM port that applications can talk to
like they would with a standard serial port. Applications can also access the device more direclty
through the provided DLL. Applications that use either interface,
although they shouldn't access the device simultaneously.
Download
the CDM driver now.
Windows 98 and Windows Me offer the same alternatives as above, although there are two separate drivers that each provide a specific acces mode. For a driver that provides a virtual COM port please download the VCP driver. For a driver that provides a direct access to the USB stack, please download the D2XX driver.
Note: if the version numbers of these drivers match the ones you have already installed from the CD, you don't need to upgrade.
