USB Ports randomly disconnecting

[Stretch]

Hey guys

So lately my usb ports would randomly disconnect . So Icould be gaming and the keyboard and mouse would go. Plugging it out and in again only works the odd time i've tried it but if i plug it out and plug them into different ones and it discoonects it wont reconnect to any of them.

By disconnect i mean the windows 7 disconnect sound plays and they cant be used. BUT lights on the keyboard (num lock) keeps flashing while on the mouse i got a few lights on it that keeps on flashing.

The only way to fix it is turning the pc off and on again and it works!
Straight away when i turn the pc back on it picks the usb keyboard and mouse back up.

I'm using a Standard dell keyboard
and a Logitech G500 Gaming Mouse


Stuff I've already tried:
-Turning off power management in device manager.
-Uninstalling the keyboard and mouse so when i restart it picks them up again.
- Ran a virus scan
- Ran Disk check
- Looked for any visable internal damage - but the back usb ports(which are directly attached to the motherboard - are protected by a metal case - No luck there.


I really dont want to replace my motherboard, I will reinstall windows this weekend just thought I'd ask for any suggestions

I get this as well, I also have a logitech mouse, the G5

I'll try my spare mouse (cyborg rat) and see if I get the same as I have a feeling its an issue with the mouse!

Have you tried uninstalling and re-installing the drivers in device manager? (Remember if you do this you will need a ps2 keyboard and mouse to control your machine while you do this)

Any errors in the event logs?

Tried it before. Didnt work

I dont think its driver related though...cause what are the chances that the Driver for the keyboard and mouse screw up at the exact same time :S

[Deathtaker27]

Nope (: but the chances of the usb port drivers could have been.

Did you manage to check the event logs and see if anything has happened?

I reinstalled windows (it was time for a good clean out anyway lol)

but before hand there was nothing in the event logs

I agree with Deathtaker. My bet would be on the usb port drivers.

Did reinstalling windows fix the problem?

I am with Skillgannon on this.

I had a G510 keyboard and Mionix NAOS 3200 mouse, now replaced with a G500 mouse.

I used to have both keyboard and mouse plugged into the same header (front input on the case). When I tried this with the G500 + G510 it threw a wobbly, like you are describing. I think it is a logitech mouse thing.

What I do now is just separate the keboard and mouse into different USB headers. So where on your mobo the two ports ontop of each other (from the motherboard point of view) I would avoid plugging into those two, instead using different headers where possible. It seems to have solved my problems.

I haven't explained this too well, so do let me know and I will MS paint a diagram so you know that I mean.

[Deathtaker27]

After hearing that Apache I recon that they are drawing more power then the usb 2.0 specification, which from doing a quick google and looking at the keyboard is a good possibility

[ApacheFlame]

Was my thought too. Seeing as you can solve the problem by not plugging in a high draw keyboard/mouse into the same hub it isnt too much of an issue, unless you only have 2 ports

[Stretch]

wow I wouldnt have thought that

Keyboard is plugged into the front...
Mouse is plugged into the back

Only time will tell i guess!
I'll update this after a week or if it happens again

Thanks for your help guys!
