I have TrackIR 4. I have had no problems for the past 8 months or so that I have had it but yesterday I installed a new audio card (Soundblaster XFi) instead of using onboard sound.

After getting that installed I booted up and the system would get to windows and then lock up and reboot. I naturally assumed it was a driver conflict with the new card because I could get into Safe Mode with no issues. After moving things around in safe mode and disabling a bunch of different startup stuff I was still having the issue.

I took a look at the bootlog and it was stopping at the trackir usb driver (npusb.sys (or something like that)). The TrackIR was connected and I could see the light lit up. I uninstalled the trackir driver and software and everything booted fine. So I reinstalled the driver and software and had no problems. Did a few reboots with no problem also.

Then while playing Lock-On my machine locked up completely and I had to do a hard reset. While trying to get back into windows I had the same issue as before and the only way to fix it was to remove the driver and software again.

Anyone run into this? Is there a problem with my TrackIR? Could there be a USB issue? Maybe a power issue making USB power to drop out with the new sound card power consumption? I am not sure what wattage my power supply is (as I am at work atm).

Thanks for any help..

Are you using other usb devices?

Have you tried moving usb ports?

Have you tried turn off any kind of power save feature for your USB ports?

In the "Device Manager" you can right click the "USB Hub"(s) that show and turn off the power saving feature that turn those ports off when idle. Sometimes that has an impact on the connectivity of the devices.

Have you tried moving usb ports?

Yes.. I have tried it direct on the computer in 3 different ports and on 2 different hubs (on my monitor and keyboard)

I did not know about this. I will try that when I get home.. I did not have issues with this prior to installing the sound card so I am assuming that is not the issue but you never know
