Logitech Wireless Keyboard and Mouse Problem with XBOX 360 Wireless Receiver?

So a few months ago i bought myself an xbox 360 wireless adapter because i got tired of playing various games using standard wired keyboard (although i don’t play a lot so i often not plugged in the receiver into the usb port). And of course it works fine until today when i tried to plug it again into the usb port because recently i just changed my keyboard and mouse into using a wireless keyboard and mouse (Logitech MX5000 Keyboard and Logitech MX1000 Laser Mouse) that is using Bluetooth technology just like the xbox wireless receiver adapter. And the problem is the Xbox 360 wireless controller can’t be detected by the xbox wireless adapter although the xbox wireless adapter already listed on device manager

At first i thought probably there’s a frequency / signal interference somewhere because both of them are using bluetooth. But after a little bit searching around the net and found this topic at avsforum.com, one of the poster there says:

Nope! I use a Logitech Bluetooth keyboard and mouse. No interference problems.
