Abstract: Individual interfaces of USB composite devices can be blocked. When a USB device is connected to a host system, a filter driver can be loaded on top of the USB hub driver and can be configured to monitor I/O control (IOCTL) requests that are sent as part of the enumeration process. When the filter driver detects that the USB device is a USB composite device, it can selectively modify the descriptors that the USB composite device reports based on the number of interfaces that will not be blocked. This selective modification of the descriptors enables individual interfaces to be blocked without filtering the USB composite class driver which in turn minimizes or eliminates any conflicts that may otherwise exist.
