Abstract
Reprogramming of a redirected USB device can be restricted to prevent the redirected USB device's firmware from being modified maliciously. A virtual bus driver can be configured to monitor USB request blocks (URBs) to identify whether an URB pertains to an attempt to alter the firmware of a redirected USB device. When an URB is identified as pertaining to an attempt to alter the firmware, the virtual bus driver can block the URB unless the URB is associated with an authorized user or application. In this way, only an authorized user or application will be allowed to modify the firmware of a redirected USB device thereby ensuring that a malicious user or application cannot modify the firmware in an improper manner.
