Hardware USB Lock

These days,data security is very important specially for military and industrial locations.

One of common ways to copy and move data is using of USB mass storage device.For example USB flash disk,USB external hard disk,USB CD/DVD drives and etc.

I’ve designed a new PCI board for locking the computer’s USBĀ ports,the USB ports in my board would works normally with human interface device like:mouse,keyboard,printers,scanner and etc,but does not working for mass storage devices.

My device is compatible with USB 2.0 specification and could work up to 480 Mb/s.

For this project i used NXP LPC2400 series micro-controller with 2 USB host controller.
