I have implemented USB Defender with the SWI-LEM 5.5 and it works well for most USB devices. If the device hasn't been white listed by its unique ID, it is blocked. If it is white listed, you can use the device.
Welcome the Nexus One Android smart phone. When it is connected to a PC, no events are logged. The user can enable file sharing from a button on the phone and then copy files to and from the device as a mapped drive letter.
I am looking for suggestions on how to stop/block this device in the same manner as any other USB device.
