    USBPORTS.SYS High Latency DPC

    Question if anyone here uses Latency monitor to "figure out" stuff with the comp as someone turned me to it the past few weeks and I have yet to have a Normal usage out of it within the first hour.

    First off, Latencymon says my USB 1.0 & 2.0 port drivers use alot of DPC count. No idea what to do about that as I used old and new drivers for the motherboard.

    My motherboard is P67 Maximus IV Extreme from Asus.



    So from here, I can also say... For those who know what Latency monitor is... I easily start getting near full redbars on the "highest measured interrupt to process latency" area.

    Fresh installed as well ect.



    Now I do know these motherboards for some reason have CRAP usb ports. So could be one reason.


    Another thing I tried is in bios as well, I even put things to Maximum performance and power saver as well as in windows. Did not really change a thing even for RED BARS in the Highest measured interrupt to process latency area.



    Dunno, just thought I would ask, as well as see if anyone thinks this program is just junk.



    Fresh installed windows has same problems ect.

    Thought I would start doing some more "in depth" checks on my computer these days and this was a place to start off in a sense.


    Thanks.
