I am trying to install logitech ex 100 cordless keyboard and mouse to use with my Dell Laptop. I have xp operating system.
When I plugged in the receiver, the computer recognized it and then said it was installed.
I have tried multiple times to connect, first starting with pressing the button on usb receiver then the mouse. The mouse then works. When I press the receiver button to connect to the keyboard, the mouse quits operating and the keyboard will not connect at all.
I purchased these product new this last week. I am using the new batteries that came with them.

the problem with cordles keyboards is that the transmitter/receiver works via usb and sometimes the driver does not have time to load for the system to start leaving it dissabled, the reason for this is whts called IRQ interupt requests. Some usb ports get left to the back of the queue when requesting that they need to start up, so unfortunately this is a common fault and may be sorted by trying the keyboard in different usb ports and moving any other peripheralls to different ones, although you will have to reinstall all the drivers as you will be using different ports, so install the keyboard first and then it may get an IRQ of 1 which means 'start me first'
