How to fix a usb composite device?

I have a n windows xp pro sp3
I recently bought an ESI MIDI keyboard (keycontrol 49+) and when I plug it in with a usb cable, it finds the hardware automatically but it doesn't work when I try fruty loops or Reason 4 music software. The music software just doesn't detect it at all and the keyboard no sound. When I look up Device manager it names it "usb composite device".
Now I have another "usb composite device" but it works and its my Micorsoft wireless keyboard and mouse. 
I am gathering that the two clash because they are both in the same location - 0 and they are both called usb compostie device.
Is there a way to fix the problem so that my MIDI keyboard and my wireless mouse and typing keyboard can work together? Or how to define a location of my MIDI keyboard so it doesn't not clash and possibly give it a different name than "usb composite device"?

This device isn't supposed to need any drivers or other software under Windows XP (or Vista).  These operating systems are sophisticated enough to recognize more than one "composite USB device," even when shown as being at the same "location."  The location almost certainly refers to the USB hub, which has two or more USB ports.

Which means only three common causes for your problem:

1.  the hardware doesn't work.  You might try plugging the keyboard unit into someone else's computer.

2.  These software packages won't work with this device.  The unit ships with a specific package in Europe, Cubase LE 4 from Steinberg.  You might have better results with this software.  More immediately, if the hardware and computer are working, you should be able to use the Windows built-in program, Sound Recorder.  From Start -->  Programs --> Accessories --> Entertainment --> Sound Recorder.  From this program select Edit --> Audio Properties.  You may need to specify your keyboard as the default MIDI device (and doing so might fix your troubles).

3.  The device possibly needs to be enabled in Device Manager  (Start -->  Settings --> Control Panel --> System -->  Hardware --> Device Manager --> Sound+Video+Game Controllers).  You can also get to these settings from Control Panel --> Sounds+Multimedia -->  Hardware.

I think it's very unlikely that you need to mess with memory allocation, as someone else suggested.

You need to manually allocate the memory locations which is a rather complex job. Try to find a Windows-savvy techie.

USB Midi Controller

the 'Add New Hardware Wizard' and force it to install the non-certified M-Audio drivers that were supposedly installed when running the M-Audio installer. (Skip internet search, and browse to M-Audio folder in Program files, it will eventually find them.) There are two M-Audio USB drivers that need to be 'forced' via New Hardware Wizard. But Windows thinks its drivers are a better match and even though 'device is working properly' it doesn't get recognized in your software. replaced them with the 2 USB ones from M-Audio, DAW finally recognized the keyboard. I even went through regedit to clean up all the M-Audio stuff so I could get a fresh install.

Good Luck you can do this /Have a great Sunday and a safe one.
