Have you tried to use the mouse in another computer to determine that the mouse if fully working. There are many reasons why it could be non-recognised. Has it ever worked on your system? Is it new and just a faulty mouse. It may be you could just take it back to the shop for a replacement one. Do other devices work in the same USB port. Some times my computer just stops recognising my USB keyboard yet it has been working for months. I found that it seems to be the USB port where the problem is. So not I just switch my mouse and Keyboard usb connectors around and it starts to recognise both again. I can not figure out why it stops. As another device is recognised suggesting the port is not faulty.
Beg M-Audio to get their drivers properly updated!
They have some for download on their site at www.m-audio.com -- but they don't appear to work on my Windows Vista Home Premium laptop Service Pack1 though I have been trying them and others all day to get Reason to recognise the keyboards existence.
My friend had a similar problem with them over a USB mixer when he went to Windows 7 - they just wouldn't update the drivers for a relatively recent USB mixer... He ended up getting rid of it. I won't be using any more M-Audio gear - not because of operational problems --but because their solutions seem to take forever and they dont usually work.
I bought a brand new Fast Track Ultra Audio card from them (my last purchase) and it was so un stable with my Mac that I sent it back. The suppliers were not surprised - It was a hardware fault but M-Audio wouldn't admit it.
Eventually they offered to REPAIR a brand new unit!!!
It has cost them dearly though, I am fairly loyal as a customer and I will not be returning to them unless they drastically sort the support side of their business out.
At the moment, they are sending a clear message to customers - DONT EXPECT PROPER SUPPORT FROM US WE ONLY WANT YOUR MONEY.
Anyhow, here endeth the rant. I am 99 percent certain that mine will end up in the bin now.

I just found this in the M-Audio forums. I've just called the number and left a message at M-Audio requesting a callback. I'm really hoping that tech support will have a solution for whatever is causing this malfuntion. . . I'll post here again when the parts come.
1) One of your USB devices have faulted, or is causing a resource conflict (or similar) -- Remove all USB devices, and reboot.
2) Your USB chip/ports have been damaged. -- Find a spare HardDisk or bacjup your data and re-install Windows and see how that goes.
3) Your Power Supply Unit (PSU) isnt supplying enough power to your PC (usually caused by a Video card upgrade). Try a more powerful PSU ... 400watts should do the trick
4) Bad memory (RAM) can cause wierd problems. run memtest for an hour to make sure your memory is ok
It seems that many people are still getting the 'USB Device not Recognized' problem from time to time. Unfortunately there is no easy fix.
Firstly, it's recommended that you make sure every one of your motherboard drivers are completely up-to-date, but you probably already knew that.
In XP, after a USB port isn't used for a long while the USB driver built into the OS sets the OHCI controller to suspend. When you plug a device back in, it can sometimes fail to 'wake up' properly. This problem was supposedly fixed in SP1 but there is a related registry hack that may still be able to help.
Run regedt32.exe and navigate to;
Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. Then restart the PC.
A long shot perhaps, but I recall having similar problems with a USB hub built into my Microsoft keyboard and adding this key seemed to solve it. It wouldn't hurt in trying .
Alternatively, removing all entries relating to USB in Device Manager and all associated USB drivers will force XP into refreshing the USB driver stack.
Begin by unplugging all USB devices, then use Add/Remove Programs in Control Panel to uninstall any USB driver software. Next, boot up into safe mode and go to Device Manager. Once in device manager make sure 'Show hidden devices' is checked under the View menu. Uninstall all device entries in this order;
1. USB peripheral devices (printers etc.)
2. HID and/or Composite USB (Human Interface Devices) You're using PS/2 input devices so you may not have this entry.
3. USB Root Hub(s)
4. USB Host Controller(s) (Universal or Enhanced Host Controllers)
Then boot back into Windows (not safe mode) and it should populate the Root Hubs & Host controllers again. Proceed to plug your USB devices back in, starting with your powered hub. Be aware that most USB printers and scanners need to have their drivers installed first before you plug them in.
Hopefully some of this may be of help, let us know how you get on.
