  • Printer showing after applying usb disable policy

    Hi,


    We have joined our 60 branches in domain. As per policy, usb has been disabled for general staff's and enabled for Executives. The policy is working fine but as a result,some printers are getting disabled and shown as offline. In device manager, we can see a yellow color icon stating it to be a USB mass storage device instead of "usb composite device". Please help...

    Regards,

    Anishk

      Hi Humannetwork,

      We have already set script to disable or enable usb on the basis of user who logs on. pen drive is working fine with the policy. The problem is with the usb printers. It is showing as offline because it seems to be detecting printer as usb mass storage device.

        Make sure you have the correct printer drivers loaded. A poor or incorrect driver is usually the cause of Windows misidentifying devices.

          Hi,

          Other printers seems to be working fine except hp 400. The same printer is having issue in most of the branches. Is that because this printer is having internal memory which in turn is making it to be detected as usb mass storage device instead of 'usb composite device' ?

            I had the same issue with an HP b/w laserjet at our office. I had installed it using the driver that came with the installation CD (printer was displayed as USB storage), then used the web update utility to update it - still did not change the status of the printer.

            I tried all sorts - downloading the correct driver from the web, etc etc.

            Eventually, it was persistence that worked. After uninstalling/reinstalling several times and running the built-in web update it eventually worked.

            It was a PITA!

              Hi,

              We at last had to give pen drive access to the printer connected machines in all branches to avoid this issue as there is no other solution coming up...!!!

              In between, Can we block only the front ports of Cabinet to avoid usb stick usage ?

                It actually (and unfortunately) makes perfect sense that a USB printer would stop working due to USB mass storage devices being blocked by Group Policy settings.

                A number of USB devices, typically wireless modems and printers, can operate in two modes: They can appear as (usually read-only) mass storage devices containing the required Windows drivers for the device in question, or they can appear as the actual device (printer/modem).

                The problematic bit is that some of these devices don't appear as both simultaneously. When plugged in, the device will start off by identifying itself as a mass storage device from which drivers can be installed. Once loaded, the driver will send a particular command to the device, which causes the device to switch to an alternate mode of operation where the storage device is not present, exposing the "real" device.

                Blocking mass storage devices will prevent the driver from loading, which in turn will prevent it from sending the requisite mode switch command to the device. As a result, the printer (or modem) never appears as a USB device.

                I don't think this problem can be solved as long as the printer is using a USB connection. If the printer supports an alternate connection type, like a wireless or wired network connection, it should be possible to make it work.

                  I suspect that the only way to do this would be disable the USB node via Device Manager. However, discovering which are for the front and back would be entertaining, and doing it on each machine a real chore. If you have a lot of machines it would be impossible.

                  Why do you wish to block USB access? Is it to prevent data from being copied to it and leaving the office (security software can do this), or to protect against software coming in, or both?

                    Another option is to connect map the printer via local TCP/IP port from the client computer. But this required the printer to have Ethernet port.

                      Hi Blood,

                      This is to restrict users from both copying data and software coming in..

                        In that case, Ser Olmy's or Humannetwork's suggestions are the way to go if these printers have that functionality.
