P8Z68-V PRO/GEN3 USB issues

Hey all,

I recently upgraded to this mobo, an i5-2500k, 8gb G.Skill Sniper 1600 RAM, and Windows 7. The only issue I've had is my USB optical mouse will randomly stop functioning. The red LED on the mouse will blink twice every few seconds. If my keyboard is plugged into the same USB hub, it will no longer function either. If I have the mouse in the front ports and the keyboard in the back and this happens, the keyboard still works. If this happens and I move the mouse to the other ports (front or rear), the PC will detect it and it'll work fine...until it happens again.

It's totally random when it happens. Sometimes it's right after boot but sometimes it'll happen 2.5 hours into a SWTOR sesssion...

Edit: Forgot to add that the mouse will also occasionally lag for a second and I'll hear the USB disconnected sound. Then it'll unlag.

I've installed all the drivers from the mobo cd, ran memtest (it said no errors found), I'm not overclocking...Any ideas?

Thanks!

I have the same exact problem!

I have to plug my mouse and keyboard on the front panel of my case for not having the problem.

By the way, the mouse also hangs in BIOS... so it's not a windows driver problem. It's the motherboard.

Only happens when plugged in rear panel.

When it happens, the mouse randomly freeze with faster frenquency and eventually, the mouse and keyboard stop working. Keyboard and mouse light flashes like if they were losing power and get it back again. Every USB ports on the rear panel stop working. I have to reboot the computer.

First time I have some kind of problems with an ASUS motherboard.

Yeah, it's exactly the same. You didn't show your mouse but I guess it wasn't working either.

Well... Mouse and keyboard froze up again yesterday. And they are plugged in the front panel!

Any news about your RMA? It's pretty discouraging...

I don't really want to get a new board that has the same problem...

Were they aware of the problem ?

I'm having the sam issue with this motherboard. My mouse and keyboard randomly stops working ( mouse flashing as it losing power ) .
Fateye, can you confirm that replaced motherboar fixed that issue ? I'm thinking of sending it to Asus as well. My motherboard is 1 week old

I have had the same problems with USB locking up, mouse freeze and system will not shut down completely.

The culprit on my setup is a HP Photosmart C5180 printer connected by USB.

If I switch off the printer before switching on the computer then all problems disappear.

I have removed all HP content on machine. Tried to install the latest HP driver and software upgrade 506Mb but the system locks half way through the install..

Tried to install the original HP CD and again the software stalls half way through.

Hope this helps.

Well, when this happened to me the keyboard and mouse stopped responding, the PC itself went on as usual, could see this since it usually happened when playing games.

I am having the same issue, and i havent been able to locate the error yet. Have you had any luck in getting this solved? it is really random for me. Can work for days, then do several lock ups in a row.

Thanks in advance.

I have been having this issue or very similar to some of the posters issues for 6-8 months now.

Usually when playing games, but on the weekend I was able to experience it just surfing the web: My keyboard (g15) and mouse (logitech USB G6 or G7 I think) loses power. To get them back, I have to unplug my usb hub and plug them back in.

Things I have tried that have not worked:

-All the different usb ports on my motherboard: p8p67 evo
-A different (plain) usb keyboard
-Replacing the power supply
-Replacing the entire motherboard (worked with ASUS support and RMA'd it)
-Replacing the video card
-Reinstalling Windows 7
-Going through all the usb settings in the device manager and shutting off the windows power save options (I suggest new people to the thread try this first, as it may have helped a little)
-I purchased a seperate USB 3.0 hub with its own power source and plugged the kb/mouse into that
-Removing all usb devices except the kb and mouse


Things I have not tried that I can think of:
-Replacing the usb mouse.

When the issue occurs, my devices lose power. I unplug (count to 5) then plug back in my usb hub. The devices will power back on and I am back running. Usually takes about 10-12 seconds total.


I would love to see this thread continue... it is very, very, very annoying.

Troy.
