CH devices not allowing screen saver to start

[tyda0501]

I have 3 CH devices, and tested them all individually. Each prevents my computer's screen saver to start. When all 3 are disconnected, the screen saver works fine. All the drivers look fine. I have no idea where to go from here. 

Thanks for any help

That's likely a windows issue.  It's been discussed in scattered places with different hardware/manufacturers causing the same symptoms (so likely not a TM issue).  I thought Windows updates eventually solved it for most, but not something I've followed closely.  I know there was a bunch of discussion in Virpil part of the forum.
