Hi All

I am in desperate need of your help! Windows Vista suddenly stopped detecting my M-Audio Radium61 USB (Music) keyboard. It was previously working perfectly and all applications could access it. However, now when I connect the USB cable the keyboard display lights up as normal but Windows does not recognise it. Vista doesn't show any error messages and it doesn't list it in device manager as it should under sound, video & games controllers. I am not sure what caused this problem but I have tried every solution I can find short of reinstalling the O/S - which, for various reasons I cannot do! Please note that all other USB devices are working normally. I have tested to see if the controller is actually working and sending a signal. I connected it to my audio interface and it is indeed transmitting midi. I have concluded that this is a strange Vista problem...

I have tried all of the following with no success.
*Uninstalled all USB ports and Sound, video & games controllers in device manager and allowed Vista to re-create them
*Uninstalled + manually deleted all references to the drivers in the registry/reinstalled (successfully according to Vista) the latest M-Audio legacy keyboard drivers (v 5.0.0) several times
*Deleted/rebuilt the infcache file
*Uninstalled other USB devices and reinstalled them to see if it makes a difference
*Tried different ports and USB cables
So far nothing has worked!!!!!

I also did a search for the driver files "MAudioLegacyKeyboard.sys" and "MAudioLegacyKeyboard.inf" but strangely I could not find them anywhere on the system even though Vista said that the drivers were installed.

I am at my wits end, please help!!!!! :ranting:

If those files are installed, they are most likely hidden files.

If you wish to make those files visible, try going to control panel and look for folder options, double click it.

When the folder options box appears look for the VIEW tab, click it.

Scroll down until you see show hidden files and folders and drives make sure there is a check mark in this box.


Then click OKAY.

Now check C:\Windows\System32\


C:\Windows\System32\Drivers (the MAudioLegacyKeyboard.sys file is most likely in this folder)

Have you by any chance tried Windows update to see if a possible missing driver is offered?
