i have an Asus p8z77-V LX2 board, bought from this site in a bundle deal.

anyway, recently went from windows 8.1 back to windows 7 (i reinstalled the board drivers from the cd) and now most of the usb connectors won't detect my mouse or keyboard (corsair k50/m30), only 2 out of 6 at the back will detect my keyboard and i have to run my mouse through the keyboard. whenever i connect my mouse or keyboard to other connectors (including front panel) windows says it can't be recognised.

is there some quick fix i'm missing somewhere?

so i downloaded the usb3 drivers from the asus page, nothing has changed.

this is what my device manager looks like, is this right?

Long shot but try uninstalling all the usb things in device manager then when you reboot after hard shutdown it will redetect them and reinstall drivers...long shot....

uninstalled both USB Root Hub (assuming they're both responsible the USB ports at the back on the motherboard, as my mouse and keyboard died straight after uninstalling both), hard booted and the other ports still won't recognize my mouse. cheers for the suggestion though buddy :)
 
the mouse lights up briefly when i put it in any port other than the usb port on my keyboard, then it instantly dies and windows says it can't be recognized :/
 
well, i'm not sure, windows won't detect the usb pen so it could be a windows problem? i've tried like 3 different usb pens and they all light up briefly then die, just like the keyboard/mouse
 
but i agree it's sounding like a board fault. great. really wanted to buy another one.

pretty sure i've had it for more than a year too, sigh
 
i went into the bios under boot options and it showed all 3 usb pens that i'd plugged in (1 at the front panel and 2 at the back).

so windows is the problem? i was also having problems with updates too.
 
Running memtest now.

It tried to install 144 updates or something as soon as I'd put windows 7 back on there, it was stuck on 0% for ages though so I left it and i think it aborted and just turnt off. then i tried to install the updates again and it wouldnt let me so i turnt updates off, left it for a day and then tried manually searching for updates with the option still turned off and apparently it installed them. Will check again after memtest is sorted
 
Well I don't think it's the bios or a motherboard problem as far as drivers are concerned - I had windows 7 originally last year with the same bios and drivers from the disc I just used now. And my problem isn't the windows update it's that more than half of my usb ports arnt working

55 mins now on memtest and no errors

To clarify, as you seem to have missed the point - Windows updates failures/issues is primarily caused by bad RAM. Bad RAM causes platform instability. Platform instability manifests in all sorts of different ways. This can include error messages when attempting to use USB ports.




Memtest does not discover all memory issues. Best way is to borrow some RAM off a friend, and test with it. So that's what I'd do first, before going and buying a new board. It might well be the USB ports on the board failing, but that wouldn't explain the Windows updates issues you experienced. So I'm still leaning towards the RAM failing.

Also, since you bought the bundle from OcUK, you could ask for assistance in the Customer Service forum.

Hope this helps.

cheers for the help. would faulty ram really cause the USB ports to play up? if it is ram related then surely both sticks arn't faulty?
 
sure,

690LC says

The drivers for this device are not installed. (Code 28)

There is no driver selected for the device information set or element.

To find a driver for this device, click Update Driver.

location: Port_#0002.Hub_#0003

pretty sure this is my antec kuhler, haven't installed the software for that yet.


the unknown device says

IUSB3\ROOT_HUB30&VID_8086&PID_1E31&REV_0004&SID_84CA1043

IUSB3\ROOT_HUB30&VID_8086&PID_1E31&REV_0004

IUSB3\ROOT_HUB30&VID_8086&PID_1E31
 
it's also worth explaining in more detail what happens when i plug a usb device into the 'non working' usb ports - windows doesn't even say it can't be recognised, nothing happens, the mouse lights up for a few seconds and then dies, windows doesn't even seem to recognise anything. but in these same ports my usb pendrives worked from bios boot up.

and another website says for these

That's an Intel device (all Intel devices have the 8086 ID). Further it looks like a USB3 hub (simple Google search on the PNP string). Drivers are available at http://www.intel.com/p/en_US/support/detect/

the detection programme won't run at all, just keeps saying it failed. i downloaded java, the web plugin and even adobe. also tried on 3 different browsers and just won't run

I know its a pain but try reinstalling windows 7.

On a sidenote, when the usb sticks appear in your bios, try the sticks in each slot and see if the bios can still see it. I'm trying to eliminate hardware issues.

managed to get them working, for the time being at least anyway. there's definitely something wrong somewhere though, i'm thinking either RAM or SSD. not gonna tamper with anything for the time being.

thanks everyone for your help, really appreciated.
