Powered USB hubs sometimes help when your laptop can't supply enough power for the device from the port. It would be a cheap thing to try.
Yeah, powered hubs are great for all kinds of things. I had a KVM that wouldn't work stably unless it was powered by the hub, because it drew too much power. I'd definitely give this a shot.
I do not understand what I do. For what I want to do I do not do, but what I hate I do.
