It's the system file needed to complete the windows Xp usb controller upade for drivers to be installed. If you don't have it you won't be able to continue with the driver install (according to the type mother board you are using. Some MoBo's don't require this.)

Gates has found another way to screw over the poor
  Demon indicates there is a version that fixes a known problem with USB ports is XP Service Pack 2. However it apparently is not yet ready for prime time and is only available from Microsoft. The version date is 31mar2005 version 5.1.2600.2644 and is referenced in document 892050. I am still trying to wrestle it from Microsoft.

Been having virus problems. I cannot use any of my virus scanners, not even ComboFix. In an AVG boot time scan it says it's white listed but it's going bye bye. I'm sure mines a virus.
My system will not recover from microsofts console on XP

Best practices for resolving usbehci issues

A clean and tidy computer is the key requirement for avoiding problems with usbehci. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the usbehci.sys process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. BMalwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
