Cannot use USB port; it is being used by another application.

Cubase

It is not just problem using Cubase and dspMixFx at the same time because it can’t work. Problem is deeper.

  1. dspMixFx closed, opening Cubase leads to crash it if you choose UR(242 in my case) driver.
  2. If you open Cubase with some different drivers it wirks fine, but when you want to change drivers to UR drivers, Cubase crashes
  3. When Cubase is closed and you want to use dspMixFx standalone, opening it it shows that UR is missing and after few seconds comes message “Cannot use USB port…”
    For information, UR is connected directly. I am not using any USB hub.
