"Detected a device change"

[Jim Stamper]

All of sudden, on opening an existing project, I'm getting blue dialog boxes in the lower right corner that say something like "detected a device change".

A couple of these dialogs flash up during the open, then disappear. There doesn't seem to be any problem from that point on.

Anyone know what causes this?

As far as I know, I haven't made any device changes or updates

Thanks

A damaged USB cable or dirty USB port can cause that.  My USB hub has the sockets pointing upwards (so they collect dust over time), and I occasionally get this when my USB headset gets moved - it's just a sign the HUB sockets need a clean again.

I do have this issue from time to time. I personally use a conventional electronic cleaner in spray to clean the USB sockets (in case you use it, remember to disconnect your PC completely from the power line before performing the cleaning)

Thank you both. All my connectors & cables were new in November. I haven't made any changes. 

But it's possible something became loose when shifting gear around on the desk. I'll check it out ?

Is it also possible that USB power saving kicks in and disconnects some USB devices....?

Personally, I disable all power saving on my PC (It's a tower)

Thanks, Yes I also do that when I first set up a PC.

But not laptops, I've never used a laptop as my DAW.
