Microsoft Windows operating systems include a bus driver and various class drivers to support the IEEE1394 high performance serial bus. However, current driver support is limited to controllers and devices that are compliant to the 1394a standard. The features introduced with the 1394b standard cannot be used in Windows based applications and device drivers. Furthermore, there are some known stability issues that cause problems in industrial and professional applications with high reliability demands. Thesycon’s alternative 1394 bus driver provides a solution to these problems. It replaces the Microsoft driver and exposes a compatible programming interface to upper layers. In-box class drivers and existing custom device drivers will continue to work.
The T1394bus driver supports all current IEEE1394 standards. It implements topology parsing and automatic speed selection. Applications can achieve the maximum data transfer rate that is possible for a connection between any two nodes. This allows the use of high-speed, long-haul and optical connections as defined by the 1394b standard.
The bus driver supports OHCI-compliant host controllers. Its implementation conforms to the PCI driver model defined by WDM and is optimized for high-throughput, low CPU load and fault-tolerant operation.
If issues arise in a particular target application, Thesycon’s 1394 experts are willing to provide technical support. To meet specific application requirements, Thesycon offers to implement modifications, enhancements and optimizations.
Customers can license the source code of the driver and use it to implement specific features or for debugging purposes.

NOTE: The driver described on this page is *not for use by end users*. It will not help solve any problems you may experience with a consumer device such as a webcam, camcorder, card reader, external sound card, etc. Thesycon’s device drivers are software components intended to be used by hardware or software manufacturers to create end products.
