I'm getting similar problems on a brand new Windows 10 HP Pavillion Desktop with Cubase 9.5
I have a Line 6 SonicPort VX and Pod X3 Live
Windows 10 is on latest version
When trying to install drivers for either of the Line 6 devices (using the correct install process in the Driver installer exe), Windows bluescreens with Line 6 Driver error messages
Stop code: DRIVER_VERIFIER_IOMANAGER_VIOLATION
What failed: l6SonicPortVX_AvsFilter.sys
I then have to disconnect USB for the reboot and reconnect, sometimes it bluescreens again, sometimes I can run Cubase for a while before reboot.
This appears to be a Line 6 problem with the latest Creators update to Win 10 my other USB interfaces are fine.
Has anyone found any workarounds and can Line 6 comment on this
