I have a security issue, we have some QR scanners that can scan lots of different 2D/3D codes. They connect on usb and show up as any ordinary HID device. This means it's basically a keyboard connected and since the scanners handle lots of codes things like ctrl-alt-f2 or so can be scanned. This units are in public places so it's just no way we can allow that and my task is to figure out how to prevent it. How can I prevent some generic qr scanners from sending anything else than [A-Za-z0-9] while still allowing a normal keyboard to be connected by some tech servicing the machine? -- ------------------------------------------------------------------- Techwiz, Peter Sjoberg GPG key (42DDDDDD) on keyserver & homepage Key fingerprint = EB81 3135 1636 576A DA83 826B 2455 0E88 42DD DDDD Homepage: http://www.techwiz.ca/~peters Pictures: http://www.flickr.com/photos/henahadu/ Enigma: http://meinEnigma.com
