Thanks, but it looks identical to the previous log, the device, at boot, didn't want to talk to the USB host (i.e. your computer), and so disconnected itself. It must have gotten "confused" and so a physical disconnect from power fixed it. That's a lot different from "it was working and then it stopped", so it might be a firmware bug in the device? I don't know, sorry. If you plug it in, after the system has been booted, does it always work properly then? thanks, greg k-h
