    Help USBport.sys Latency Issue Major Problem


    I have been having this strange memory leak for the past few weeks where my system will all of a sudden be incredibly bogged down, and the audio will start to crack and break as I am watching something or gaming. I thought it was a compatibility issue with my onboard sound, but I turned that off and the problem still persists. Today I was reading and I thought I would test my latency, and I found out that the USBport.sys is causing major latency issues in my system. The problem is that no matter where I look nobody has a real solution. Some have said that Windows released a patch for it, but when I tried to install the patch it told me that I already had it on my system..... Additionally, when I restart my computer it is generally fine for a day or two, but then it begins the cycle all over with latency problems.

    I could really use some help to figure out why this is happening... I am open to any suggestions from anyone out there who might have some knowledge on this subject. I will try my best to provide any additional information that people may need to help me diagnose this issue completely. I should note that I have done a full virus/malware scan and found no issues. I have also updated all of the drivers on my board to see if that will fix the issue.

    Thank you in advance.

    I should also point out that I am using LatencyMon to monitor the latency in real time, and I literally just restarted and I am already getting issues with my audio. Something is definitely wrong, but I want to avoid formatting at all costs.....

    Open an elevated command prompt, type in sfc/scannow and hit enter. USBport.sys is a USB 1.1 and 2.0 port driver (Link) handled by Windows Updates so if there's a problem with the sfc/scannow may rectify it.

    Report back with the results.

    Try this: (This will uninstall all usb devices and force re installation on reboot.)

    That should resolve any issues you have with usb devices unless it is hardware related.

    I decided to update my system to Windows 8.1, but the problem seemed to persist through a complete wipe of my entire system. After updating every single driver I think I might have fixed it.... I still have a few errors that I am not sure of such as 1002 and 7000. The 1002 only happened once while I was playing Sleeping Dogs, and the 7000 error has only happened a few times. I am pretty sure the latency is gone though, but I am not sure how to check. I was told that LatencyMon is a bs program and not to use it. I haven't really noticed any drop outs since all the drivers have been updated..... how should I test it?

    Any suggestions?
