Mass Storage Controller is PCMCIA Device Driver in notebooks. If your Toshiba has Card Reader than go to Toshiba's WEB Site and Down Load driver for Card Reader or PCMCIA Driver for that Model Notebook. If Windows 7 Ultimate drivers are not available, try using Windows Vista Ultimate drivers. This will remove "Mass Storage Device" from Other Device Property in Device Manager and install the driver for that other device with correct device identification. This is not intel's driver error. Intel do not have driver for this. Trust me, it will work.
