[SOLVED] USB 2.0 Ports Losing Input?

post #1 of 8
Thread Starter 
K, so this is a weird problem. Since last Saturday, I've been randomly losing connectivity through my rear USB 2.0 ports.

My keyboard and mouse will be unresponsive for a second or two (the unplugged peripheral sound plays) before recovering on its own, and it will happen more and more frequently until they stop both responding altogether.

Unplugging and replugging them in doesn't do anything, but restarting the system returns everything to normal.

Oddly, it's not as cut and dry as that though. First of all, this only seems to affect my rear IO USB 2.0 ports. When it happens I can plug my keyboard and mouse into my rear 3.0 ports or my front panel 2.0 ports and they work fine.

Also, the rear ports aren't completely shut off. I can still plug in my MP3 player or a flash drive and read from them. I cannot however use ANY input device through them when the ports bug out.

It's weird. Plugging in my mouse/keyboard/controller to the "bugged ports" will play the peripheral connected sound and do the standard driver check, but they'll be completely unresponsive.

I'm at a loss here

Edit: and yes I'm using the latest BIOS/drivers officially released.

Bad/cold solder joint on the USB connector legs. OR someone has rammed a USB plug in backwards thus damaging the USB socket. If only I had a dollar for everytime I've seen that one.... what happens is the center tab breaks off from it's base. This tab holds the pins/pads and at the base of it where it's broke it shorts out when you insert a connector. Very very common...

Hmm, well I've had this mobo since the beginning of June, the problem just started a few days ago though. Wouldn't that have been apparent from the start?

I can definitely rule this one out

Well if the USB socket appears ok then it could be one of two things. The USB connector legs have a dry solder joint that has loosened up or the voltage parts that drive current for the port are damaged. It could also be some strange software issue. Or it could be the USB device it's self. Have you tried other USB devices in the same port?

I don't understand what your saying there as it contradicts it's self. When they "bug out" they don't work at all but your MP3 player and flash drive work? Doesn't make any sense... Sure your not confusing the fact there are TWO usb controllers feeding ports on the back of that board. The Intel southbridge USB and the NEC USB3 controller.

Did you install the chipset drivers from Intel?

What about your overclock. It could have become unstable and your having IO issues between the south and north bridge due to DMI clock/bus damage. Don't ever adjust BCLK/DMI/PEG above 100Mhz !!!! Doing so with a K processor is RETARDED IMHO

Yes, no input devices (keyboard/mouse/gamepad) work once the ports bug out.

I'm not saying they don't work at all.

I'm saying that I can't use any input devices on them. The ports aren't "dead" because anything I plug into them is instantly recognized by windows, and I am able to read info on my storage devices (MP3 player/USB drive etc). But any input device that is plugged into those slots is completely unresponsive (despite being recognized by windows).

Yep.

Nope, I don't even OC this proc except for benching (I'm nowhere near CPU bottlenecked at my res) and never touched the baseclock.

Did you ever 'tweak' the hertz setting on your USB ports? That can and does cause problems after a while..

Nope! Found out what the problem was though. My POS logitech MX518 was dying and apparently after "disconnecting/reconnecting" itself X number of times my ports get bugged until restart.

Zero issues since replacing it.

OT: The MX518 has to be the worst mouse I've ever owned. I've had 3 of them die on me and be replaced via RMA. This is the first time one of them has caused this much trouble though.

I have a Logitech G5, a second one mind you, that exhibits the disconnecting problem as well. I've since stopped using Logitech mice, even though I love their feel/style.

Good to hear it's sorted!
