Oh, god! Where do I even begin?

[Whackjob]

Ok. Some of you are aware that about a month ago I managed to finally destroy my old laptop computer. I've been in the process of building one. Construction and assembly went very well, and I ran into no problems. The day my RAM finally arrived, I was set. It booted up and ran fine, and all I needed to do was redo the graphics drivers. No sweat. Even fired up KSP and built me a little test rocket to see how things changed.

Now I've run into a problem. A rather serious one.

After fooling myself into thinking I was fine, I disconnected all the cabling to move the case from on top of the desk to under it. And the weirdest thing happened. The mouse would no longer work. It's a Rat 3 USB mouse. In frustration I hauled it up on top of the desk and went to work. I removed and replugged in the mouse. Windows doesn't notice. I changed USB ports. Windows didn't notice. I unplug an external hard drive dock that was functioning fine. Plugged the mouse in there. Windows didn't notice. Went through device manager and removed and re-added all HID compliant devices (also shutting off my keyboard lol). Rebooted. Still the same effect. Tried to download and install the specific mouse drivers. Refused to install because it didn't detect the mouse. Went through Win 8 settings, removed fast boot option, disabled any sort of USB power down, rebooted. Still no effect. Even completely reinstalled Windows 8. No effect.

I even went so far as to load up Ubuntu from DVD, and just ran it off the disc rather than installing it. Ubuntu did not see any USB mouse. For me, that's the clincher there. It's not a software related issue. It's a hardware one. Tried to post here earlier for help, but can't with a keyboard only. As soon as I start typing a note, I have no way of tabbing out to hit POST.

For any tech savvy folks who are more up to speed than I am, I'm using a Gigabyte motherboard, specifically GA-78MT-S2P. If anyone can dream up some sort of fix, I will be eternally grateful.

But, until I find something that works, I'm hosed. Stuck. Trying to dig up a PS/2 laser mouse from somewhere in the meantime.

I think you need to get a new mouse :/

I find it's worth having a spare mouse just in case, even if it's a crappy wired 2 button job.

Edit:

You can't make things worse by opening the mouse and looking for bad wires at this point I expect, maybe you'll be able to get it working, got a soldering iron?

[godefroi]

Did you try a different USB mouse?

[MalfunctionM1Ke]

Is this your old mouse? Dont know if it took some damage when your old PC blew up.

Maybe you should try a USB-Driver update from the Gigabyte Website but i dont know how to do that without a mouse :/

[Whackjob]

I have tried other USB mice. System doesn't see them plugging in at all. The mice do get power. And other USB devices work fine.

Another odd symptom: System also does not see a USB headset plugging in. But it does see external hard drives. And I can access them fine.

#EDIT: Next-day-air ordered a PS/2 laser mouse. Just in case.

[sal_vager]

Hmm, I think I had something similar happen, I had a dodgy USB hub that was preventing the PC from booting (how I do not know), can you test the PC with no other USB devices except the keyboard and mouse?

Not even external drives or hubs.

Also, check your bios/uefi for legacy mouse compatibility mode.

Yeah, removed everything but mouse/keyboard, plugged directly into the computer. Not even using a hub. Rebooted. Keyboard works, doesn't see mouse. Also checked compatibility mode in BIOS... saw legacy and regular? Forget name of regular. Left both enabled. Think I need to disable the current version?

Did update BIOS to most recent version. Downloaded every driver I can think of. Just can't use mouse driver because the system doesn't see it.

#EDIT: Worst and best part of this is tomorrow and the day after are my work weekend. Meaning I got all the time in the world to work on it, but won't be able to post if I don't fix it. Which means I might be offline again for another two days =\

#EDIT2: Additional weirdness. I can switch the plugs I use for keyboard and mouse, and the keyboard picks up. So it's not a bad port.

Maybe you have one of those usb to ps/2 adapters lying around? Also it may be worth disabling those modes one at a time, see if it works.

Other than that I don't know, if other stuff works it can't be the ports themselves, and it can't be the OS or driver, or the mouse if others also don't work.

[FenrirWolf]

My mouse never had any problems, but I did have an issue with certain USB peripherals with my Gigabyte board too. In my case the problem was related to a certain device not playing nicely with USB 3.0

By default even your USB 2 ports are controlled by the USB 3.0 XHCI driver, but there should be options in the UEFI to route the USB 2 pins using the legacy EHCI driver. Might be worth trying at least.

[Whackjob]

Nope. Had one ages ago, but not anymore.

Also it may be worth disabling those modes one at a time, see if it works.

Oh, good grief! I didn't even think of this! Thank you, will try that one when I de-office.

Other than that I don't know, if other stuff works it can't be the ports themselves, and it can't be the OS or driver, or the mouse if others also don't work.

Yeah. It's a puzzle.

Bit of a long shot, probably you've already tried it, but...

Have you tried every usb port on the mobo? They are not necessarily all tied to the same USB controller chip.

Also (and again I'm assuming you've been through this), I've once or twice had cases where Windows takes an absolutely inordinate amount of time to pick up mice / keyboards. Sometimes giving it fifteen minutes to sort it's st00f out works wonders.

Any unidentified items in the device manager?

Come to think of it, when trying it under Ubuntu, do you get anything showing up in dmesg when you plug the mouse in?

[Whackjob]

I've put both keyboard and mouse in every USB port from the motherboard. Keyboard always works, mouse always does not.

I've had it sit for a few hours already. No effect.

None. It's not even coming up as unidentified. It's totally undetected.

Not familiar enough with Linux to try that hehe.

[sal_vager]

You can start a terminal in the live session and type in "dmesg", this will give a list of stuff detected on the system including the mouse.

Also you can install programs to the temporary RAM disk when using a live CD, they are lost when the PC is rebooted, by installing hardinfo with "sudo apt-get install hardinfo" you can get a nice graphical system profiler that is a lot easier to read

Not familiar enough with Linux to try that hehe.

1: Get to terminal

2: type dmesg

3: look at output

4: plug in mouse

5: type dmesg

6: any new lines should refer to the system picking up the device (or not).

[Whackjob]

Ok. I burned Ubuntu into a disc and still have that handy, so I'll try that also if messing with the USB in BIOS doesn't do the trick.

#EDIT: Gonna have to look at some ubuntu tutorials so I can figure out how to pull up the UI haha

[sal_vager]

This should help

[pxi]

Beyond the list above, it's also worth knowing you can get to the four text-mode terminals with CTRL-ALT-[F1 -> F4]. CTRL-ALT-F7 will bring you back to the window manager.

It can be a godsend when something hangs the desktop.

Ok. I just love problems like this, NOT!. It sounds to me like there is some sort of issue with windows 8 getting confused. If I understand correctly, the new machine was working fine until you moved the computer, and after hooking up everything again, you could not get the pc to recognize the mouse, but it would recognize the keyboard, strange indeed. Maybe you can trick Windows 8 into fixing it for you, if in the crazed process of trying everything under the sun, you haven't already screwed the bios.

Try this:

1. shut down the computer

2. unplug all usb devices.

3. turn on computer

4. plug in mouse only at the log in screen.

Following these steps exactly may trick windows into reloading the drivers for the mouse. The only thing I can dream of is that somehow windows did not properly unload the driver for the particular usb port it was plugged into and it's now hung up or froze.

Anyway, I'll be watching to see how you fix this Whackjob, cuz my curiosity is piqued.

Gave that one a shot last night. As expected, didn't see mouse. Removed mouse and plugged in keyboard. Saw it. Just not the mouse.

Ok, sorry man. Sometimes it helps to check if the lawnmower has gas before you pull the rope 50 times. Sometimes the pencil you just lost is still in your hand. Anyway, good luck! I can't wait to see more of your creations.

[6.forty]

Disable USB 3.0 in the BIOS if you have the option, although I'm not sure the -S2P has USB 3.0. Also make sure 'USB Wakeup from S3' is enabled, and check if moving the mouse or clicking a button wakes the computer from standby/suspend. And just to be complete, try the mouse on another computer.

The output of dmesg and lsusb right after plugging the mouse (or the USB headset that didn't work) may help, even if it's a picture of the screen taken with your phone.

No need to apologize at all. I appreciate having another brain looking at this problem with me. And you're quite right hehe... sometimes it's the obvious, overlooked thing.

IS it USB 3.0? I had a customer uninstall USB 3.0 support by mistake and had this same problem. I had to re-install via serial mouse or keyboard input and google/manufacture drivers. Hope it helps!

PS, it was funny, as the same customer drove 20 miles to talk to the "PC experts" to fix his mouse. They obviously tested it and it was ok and working. I never did ask why he did not call me first to fix it. Oh, and it happened as his daughter was trying to get "free sky", and installed all these useless apps, but ended up uninstalling the USB drivers when taking off the apps.

PPS, by that I'm suggesting Windows might have messed up the 3.0 drivers (likely your unplug triggered a normal shutdown/Windows update which is the cause, and not a breakage in carrying. ), and not that you messed them up.

I had a problem kind of similar with my r.a.t 7 - i redownloaded the saitek drivers and reinstalled them. I think those mouses maybe quite too far off the HID system to work correctly with generic drivers.

[Whackjob]

The mouse is USB 2.0, the motherboard has 2.0 connectors. No USB 3s anywhere. Now I'm idly wondering if I tried to install USB 3.0 drivers by mistake.

#EDIT: Which is irrelevant, I just now recall, because they still did not work right after reinstalling the OS.
