After reading a thread here I purchased a Genius 300 as an MCE 2005 replacement. Fresh install with all relevant updates etc. However the IR receiver installs as an ‘Other Device’ not as a ‘USB Device’, in hardware manager, hence drivers wont work. If I plug in my standard Microsoft IR receiver its fine, it installs automatically in the right place in device manager and all is hunky dory. Its not the hardware as it works fine under Vista on my laptop. This problem has plagued me for years with a number of remotes, which is why I have 3 useless remotes lying round. Its like the hardware needs to be forced to be recognised as a USB device.   If anyone can give me a solution that works, you can have one.
