USB protection method currently allows locking of protected applications to any USB storage device like external usb hd drive, usb flash drive, usb card reader or even usb hub as long as there is valid serial number associated with such device.
Starting from next update, PC Guard will also allow locking to USB network adapters. USB NIC MAC address is used for locking in this case.
This means that locking will depend on selected USB device type (USB storage device or USB network adapter device).
Final testing is underway and we expect to release new version of PC Guard soon.
As always, we are looking forward to your comments and suggestions!
