JSI Tip 8939. The performance of 1394a and 1394b FireWire devices are decreased after installing Windows XP SP2 (Service Pack 2)?

One example of this decrease is a digital camera to uses S400 speed, running at S100 speed after the upgrade, because SP2 changes 1394b ports to S100 speed.

To resolve this issue, visit the Microsoft Download Center to obtain the Update for Windows XP (KB885222).
