IEEE 1394 Bus Driver in Windows 7 • • 4 minutes to read • Contributors • • In this article Windows 7 includes 1394ohci.sys, a new IEEE 1394 bus driver that supports faster speeds and alternative media as defined in the IEEE-1394b specification. The 1394ohci.sys bus driver is a single (monolithic) device driver, implemented by using the kernel-mode driver framework (KMDF).

The 1394ohci.sys bus driver replaces the legacy port driver, 1394bus.sys, and the primary miniport driver, ochi1394.sys. The new 1394ohci.sys bus driver is fully backward compatible with the legacy bus driver. This topic describes some of the known differences in behavior between the new and the legacy 1394 bus driver. Note The 1394ohci.sys driver is a system driver that is included in Windows. Controller Ieee 1394 Driver for Windows 7 32 bit. Controller Ieee 1394 Driver Download.

This article will show you how to correct IEEE 1394 Problem in. Fixing FireWire Problems With. Or 8 or 8.1 you will need to download the Legacy driver from. It is automatically loaded when you install a 1394 controller. This is not a redistributable driver that you can download separately. • • • • • • • I/O Request Completion All I/O requests that are sent to the new 1394 bus driver return STATUS_PENDING because the 1394ohci.sys bus driver is implemented by using KMDF instead of WDM. This behavior differs from that of the legacy 1394 bus driver, in which certain I/O requests complete immediately. ![]() A client driver must wait until I/O requests sent to the new 1394 bus driver are complete. You can provide an I/O completion routine that is called after the request is complete. 1394 Firewire DriverThe status of the completed I/O request is in the IRP. Configuration ROM Retrieval The new 1394 bus driver tries to use asynchronous block transactions at faster bus speeds to retrieve the contents of a node's configuration ROM. The legacy 1394 bus driver uses asynchronous quadlet reads at S100 speed—or 100 megabits per second (Mbps). The 1394ohci.sys bus driver also uses the values that are specified in generation and max_rom entries of the node's configuration ROM header to improve the retrieval of the remaining content of the configuration ROM. For more information about how the new 1394 bus driver retrieves the contents of a node's configuration ROM, see. IEEE-1394-1995 PHY Support The 1394ohci.sys bus driver requires a physical layer (PHY) that supports IEEE-1394a or IEEE-1394b. It does not support a PHY that supports IEEE-1394-1995.
