Abstract
Communications are intercepted between a universal serial bus (USB) device and a host, at least by implementing first device firmware of the USB device. The USB device contains its own second device firmware. Using at least the implemented first device firmware, intercepted communications from the USB device toward the host are sanitized. The sanitizing is performed so that no communication from the USB device is directly forwarded to the host and instead only sanitized communications are forwarded to the host. Methods, apparatus, and computer program products are disclosed.
