Virus TI lost communication in Cubase 6.5

  • Hi

    My Virus TI lost communication since i installed the Cubase 6.5 update.
    Before never had a problem with it.
    I need to remove the USB cable from the Virus and re attach it in order to the editor recognize it again.
    I'm on Win 7 Ultimate 64,Cubase 6.5- 64 and i have a PCI USB card just for the Virus TI.

    Any suggestions? or anybody else having the same issue?

    Thanks in advance
