Windows 10: High DCP Latency from usbport.sys - Can't find the culpril

Hi All,


My Windows 10 desktop is having an issue with driver usbport.sys peaking and causing constant pops, clicks, and delays in my audio. This issue is happening for both my external soundcard for recording (Focusrite Saffire 6i6 USB), and for the internal sound card. I've restored my only system disk image to try to revert back to before I had the issue, but that didn't work. I've uninstalled all unused drivers in device manager, as well as uninstalling almost every active driver in there and either installed the newest drivers or letting Windows 10 install it's recommended driver. I've downloaded the Latencymon app and it goes for seconds at most before showing the usbport.sys spike. This issue happens when I'm using either the regular USB ports on the computer or having all my USB devices plugged into a docking station, but either way if I start Latencymon and unplugged all devices, the usbport.sys driver will still spike, despite absolutely no devices plugged into USB.

Last night I was so frustrated that I did a fresh install of Windows. No issues from 1-2am, but upon waking up this morning and checking, the issue was back.

Plugging all of my same computer devices (trackball, keyboard, audio interface) into my laptop produces no latency issues at all. Does anyone have any ideas on what I might try next to stop this from spiking? It's at the point that all music and sounds are garbled most of the time.



Thanks!

High DPC Latency caused by wdf01000.sys

Hello,

I am posting this regarding a problem that I ran across in my laptop at the beginning of august 2019, the problem is that I am getting high DPC Latency levels that are apparently caused by wdf01000.sys according to the latency checking
program, latencymon.

I really want to know if there is a fix since I have browsed a wide range of sites trying to find a fix, I could not find any. And also my keyboard stopped working for some reason, if its ok I would like to find a fix for that, but
I prioritize fixing the high latency over the keyboard.

Thank you for taking your time to read this.

 

DPC Latency with Storport.sys and Wdf0 1000.sys


Sorry when I went to post it looked much better than it does there.... So I can see how that wasn't the greatest piece to look at.

Here is the screenshot you requested.








Power Plan Settings: High Performance
Turn off disk after: 20min
Sleep/Hibernate: Never
USB Selective Suspend Setting: Enabled
PCI Express Link State Power Management: Off

Processor Power Management

• Maximum Processor Frequency: 0MHz
• Minimum Processor State: 100%
• System Cooling Policy: Active
• Maximum Processor State: 100%

I believe the Power settings are mostly the generic High Performance. If I changed anything it was the sleep function as I often access this computer when I'm at home.

As for staying with my old computer. I agree, I definitely could have, but it had been 3 years since I last built that system so I figured it was time to step it up. I also use the Creative Cloud often and my system could use a boost in speed. Plus the old components are now in a second tower and being used for offloading things to free up this computer for recording (such as rendering video, etc).

I plan to add 32GB more to the RAM over the next two months and a new 1080ti video card. Someone also told me adding an internal Soundcard might help as well, although I don't see what it has to do with this latency issue.

Thanks again,

Brad

 

Sound stuttering and high latency from Wdf01000.sys and ACPI.sys






Unfortunately updating logitech software did not help.

So is there any way to find out which program or hardware uses that Wdf01000?
