supported.
For Linux, a 2.6 kernel is required. The standard CDC-ACM driver will work.

install.bat from the UIP_VCOM_autoinstall directory on your product CD and proceed with the procedure below.
Note: Certain levels of Windows have an issue with their CDC-ACM driver (Usbser.sys). If you are having connection problems
(file download, web pages not loading) your version of Usbser.sys must be updated. Microsoft article 925681 documents this
issue and provides a fix.
