Spectra not installing properly

Spectra not installing properly

Hello I have two MF spectras that are causing me headaches with Windows 7.

When I plug them in (even after installing software) they keep resetting and going through the start up pulse. When I check device manager it tells me that the USB Input device can’t start. I have tried forcing drivers but while it finds the Spectra and composite device it fails to install the input device.

Both spectras appear in MF utlity but only briefly before restarting.
