So a couple of months after my latest new install, i stared running into this problem of my mouse losing power. It wasn't much at first, a second here and there and the game freezing up for a bit. Every now and then windows would tell me a new device had been plugged in and installed, sometimes not, and sometimes Steelseries engine would tell me my Sensei was connected.
So after a week or so of this problem persisting, my keyboard started dying as well, same symptoms as above, but with an increase in severity. Freezes got longer, sometimes over a minute, and at one point i had to reboot to get the mouse and keyboard to work. I tried a lot of things, i used to click a lot on mouse 2 while playing HoN, i mean 200+APM a lot so i was already familiar with USB-hub power settings, tried shutting that off first. That didn't do much at all, so i decided to switch to my old Logitech MX518 mouse to reduce power consumption.
This helped, for a while, but soon enough, within a week, the MX518 was doing the same thing, losing power at the most random of times. So I'm quite puzzled as to what this really is, I'm trying to play CS:GO with my buddies but not having a working mouse when we push bomb sites because "I'm not sure" Isn't really working out for me no more.
I've tried msconfig processor count, because someone mentioned they got the same problem when that was not set to the right amount or deselected. Tried disabling MS Multimedia Class Scheduler, Nothing.
I've tried setting power management for all USB human interface devices in device manager. I've also tried with the emergency low-power state setting as disabled and enabled, no difference.
There are 2 devices in device manager that have faults: SM Bus Controller and Unknown Device. Can't seem to fix either.
I've tried turning off LED's, lowering polling rate, using an older mouse for lower power consumption, didn't work.
I've looked through Event Viewer and the only thing i can see is the occasional "couldn't find device: cdrom", I don't have a CD-ROM, i only hooked one up to install windows. I lack the windows technical knowledge to know whether or not this could be an issue, but i assume not.
I tried USB deviewer, and cleaning up in drivers and installing new ones, for everything. Also deactivated all the pointless windows features that also sometimes cause mouse issues like these.
Also tried disabling USB 3.0 in BIOS if that could be screwing with things, no issue, just 2 less USB ports i don't use. Also tried the V/HScrollHighResolutionDisable 1 registry key adds.
I'm sure I've forgotten something in here as well, but I'll leave the post like this for now and hope any of you guys have some input or things i could try out to solve this. I've yet to try a new windows install or a different keyboard, but I'll be trying another keyboard sometimes in the next days.
From what i can see this has been a widespread issue since 2009, with no actual fix, which boggles my mind. Usually its introduced with a windows update, and theres some conflict with a video card update and shared irqs, no idea what that includes or how to fix it, but looks like a new install and beating windows update to death with a teaspoon is first on the list.
