    DH87RL - Problem installing printer (Canon iP4950)




      I'm facing big problems when trying to install my printer Canon iP4950 on my new machine,

      although printer and driver seem to be Windows 7 (64bit) compatible!

      (This printer was working without any problem on my old machine with Windows XP !)



      - DH87RL

      - BIOS and all drivers updated to newest version

      - using Windows 7 Professional, 64bit, SP1 + all updates and patches so far

      - newest Canon printer driver 64bit, v2.56 (for Win7 and Win8/8.1)


      When I install the Canon drivers, I can see two devices to be installed:

      1.) USB printing support

      2.) iP4950 printer


      After the installation the printer is recognized and works like expected!

      BUT.... when I turn off the computer and restart again, there will be installed an "unknown device" (USB) instead of "USB printing support".

      So "USB printing support" is no longer active and therfore my printer won't work any more!


      I can reinstall the printer by first manually deinstall the printer driver and also "unknown device" and "USB printing support" in device manager.

      But this will last only until I restart again... !

      I tried with different USB panels (2.0 and 3.0) and with different cables also.


      Can anyone give me some hints or tips to solve this issue?

      Thank you in advance for your help!
