Windows 7: win 7 + logitech ex110 cordless problem

hi, all was ok and after removing from usb ports and reconecting sudenly my keyboard and mouse is not recognized again and now not work....
i try reinstall drivers, change ports, even try keyboard on another comp and there work...
i try and remove all usb devices from control panel and install again all and all was instaled corectly but ex110 is not recognized...
any sugestions?
thanks

Does that keyboard + mouse have a receiver with a connect button? Press the button on the receiver then the keyboard and mouse. Do you have any other wireless or bluetooth devices around your desktop/laptop?

i was changin graphic card and i was remove all usb devices from case.
after reconecting all work exept keyboard receiver...
have reconect button but no light on it like was before...
its not recognized by windows..
i try first drivers/restart and then connect and dont work..
i have dual boot with xp and in xp after reinstall all work but on win 7 dont

Did you connect the USB headers on the front of the case properly?

yes.
like i said, in dual boot when i go on xp all work, and win 7 cant recognize it...
i put same drivers like was before

Hmmm, have you tried the USB ports in the back of your motherboard? If it works in XP, does anything show up when you connect the keyboard in 7? Is the device recognized?

i try even change it with cam and still device not recognized
on xp all work perfectly but win 7 cant recognize
i remove old drivers from comp, reboot, install new drivers that was working before,
reboot again, connect and still nothing.
and like i said, on dual boot win xp all work perfectly...didnt even need to reintall it

Try looking here:

Does a box come up asking for drivers? If it does use the disc, if it doesn't buy a cheap PS/2 keyboard if your motherboard has a port for it - it most likely will. If you play a lot of games, consider a Razer keyboard like the Arctosa, if not, then the other option should cover you.

nope, just said not recognized...try mynual still dont work..
few days ago all works fine

If it worked then, use system restore. Did you install any new software or drivers apart from the video card?
