Just a little update: I took into consideration and I remembered that I have a PCI-E internal card and plugged it in. It fixed the issue 90%. I've never been so happy seeing green. Not only that, it boosted my entire pc's speed up, as well as network speed. Before it used to deteriorate to as low as 2 mb/s but with this card its back up to 17-ish. For all you dealing with the issue of usbport.sys and the cause being your network adapter, try a pci-express internal card. A decent one can be very cheap.

You can get an original .iso through DigitalRiver downloads: http://www.heidoc.net/joomla/technology-science/microsoft/14-windows-7-direct-download-links jaclaz Wow thanks. I guess what's sold is the product key, not Windows itself. I will keep this downloaded but I'll wait for Andre's response before I proceed. Sure thing, here's the link : http://www.mediafire.com/download/2it0fizmiu41t0t/latency.etl As well, I'd like to add that after all Windows Updates, I even used DriverEasy to update all drivers. It found lots of usb port drivers, installed them all but still no good. As well, my USB 2.0 ports are also not working as they used to before the hardware changes.

Hi Andre, I saw your post from a couple years ago of finding the cause of high DPC latency issues and followed all your instructions. Before I continue, I'd like to state that this all happend after I replaced my motherboard, CPU and RAM as well as re-installed windows. What I get is obvious very high DPC latency usages, WHEN my internet adapter is turned on from device manager. When disabling it or plugging it out from my computer, my DPC latency usage drops immediately down to the green levels. So, I re-installed my network adapter, no good. I made sure all the drivers were 100% updated from the website itself, but still no good. I even changed my network adapter with a brand new one and made sure all drivers were updated but still no good. This would conclude that the usb port was the issue. To confirm, I followed all your steps and arrived at a shock. Dumping the files into a .txt I noticed that a number of .sys were caused by this. (I private messaged you the info) So, I did the logical thing and installed all windows updates, re-checking for new ones right after. After a while of downloading, installing, not one difference was made. It does not contain viruses since it was directly after a fresh install. Now, this leaves 2 possible causes. 1. The new hardware (CPU, Motherboard, RAM (6GB) - I also added a new cpu cooler with new thermal paste and brought the CPU temp down from 73 degrees to 35 degrees, which eliminates overheat. - As well, I fully cleaned the PC of dust. 2. A bad installation of Windows 7. After my first failure with high DPC latency, after failing to fix it, I re-formatted windows once more to see if the issue would resolve, but the issue still remained *Note* I purchased windows 7 a while ago, ultimate edition but at that time all I used was the 32-bit CD and so I accidentally lost the CD to the 64-bit version but I managed to keep the Product key. So, not wanting to pay a couple hundred dollars again, I pirated (bad, I know) a copy of windows 7 onto a CD to re-format it both times. When I used my purchased product key it worked just fine. I would really appreciate the help because the choppy sound, extreme lag is unbearable and I am left completely out of options after trying everything. Thank you, Tacent.
