Query: Windows 7 support defective

The hardware may very well be acceptable, but the claimed Windows 7 support for this device is defective. The install disc simply exists saying "your operating system is not supported" but the m-audio has a Windows 7 (64 bit) driver. However after an apparently successful install (after which the device manager claims the unit is connected and working properly) every attempt to send sound to the unit causes the source application to hang. After much trial and error, I found that the unit will work if you go into the control panel, click through numerous dialog boxes and reset the unit to "default" configuration. The M-audio supplied control panel has no effect. After every reboot, the device is inoperable again and the time consuming reset procedure must be repeated.I don't know if the thing works better with other operating systems, but I'd advise anyone with Windows 7 to avoid this unit.
