Device Support File Usage
FieldComm Group (FCG) makes available to its members and to the public certain device driver (DD) files, in various forms, that have passed certain tests conducted by or through FCG. The DD files are, or are created from, submissions to FCG by FCG members and are provided by FCG AS IS. FCG disclaims all liability for the accuracy, suitability or use of the DD files. Each member creating DD files has its own policies regarding supporting use of those files, and may, for instance support use of DD object code files, but not DeviceInfo or other files. While FCG is under no obligation to provide support for use of any DD files, FCG welcomes all inquiries on the subject and will often be able to assist.
