Issues with Logitech K400 keyboard not working in win 7

[B420]

hi. i have logitech k400 wireless keyboard with touchpad. it works fine in bios and in xp but on some reason it does not work in win 7.

it detected the device when i plugin the small wireless device and says "ready to use" but nothing is happening. keys are not working, touchpad is not working, mouse buttons are not working (touchpad buttons).

there is no driver cd that came with the keyboard it is plug n play.
it worked almost instantly in xp, 1-2 seconds and worked.
what is going on?

my main keyboard is saitek cyborg v7. if you think it conflicts, then earlier i used a mini wireless keyboard with touchpad and it worked fine under win7.

somewhere on logitech site i read that someone had similar issue and that he said it worked in safe mode because some program was blocking it?@!
i have not tested in safe mode but something tells me it will work
either way i dont care about safe mode. i know keyboard is fully working and i need it with my win7 machine.

any suggestions?

anyone?? i still cant get it to work

ok i found a fix that was found on this forum under different topic with different device.
someone had issue with different logitech wireless keyboard.

so what causes this problem is "motioninjoy" gamepad drivers. i had to completely uninstall the software in order to get it working. no restart required !
there might be other programs that cause similar issues, but that is one of them...

i still need my motioninjoy drivers tho!
