<div dir="ltr">So confused. Downloaded Ubuntu 20.04 (ubuntu-20.04.2-desktop-amd64.iso) and booted my laptop to a liveCD environment. Watched all the systems logs and plugged in. UPS did it's "REMOTE SHUTDOWN". Nothing of interest in the logs. Unplugged the USB and waited about 5m. Plugged USB back into my laptop, nothing, unplugged... Rebooted the LiveCD environment, plugged USB back into my laptop, nothing, unplugged... VERY stumped, plugged the USB cable back into my NAS, and everything is happy.<div><br></div><div>I know the problem is still there. I know it's going to bite me again, but I can't seem to reliably trigger it. Very frustrating.</div><div>Thoughts?</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Thu, Feb 4, 2021 at 2:53 PM David Zomaya <<a href="mailto:David_Zomaya@tripplite.com">David_Zomaya@tripplite.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">On a quick check, I'm not seeing the problem with Ubuntu 20.04.1 and an SU1000RTXLCD2U (4004 for USB). Reboot the box and disconnect/reconnect cable were both ok.<br>
I'll look into it more.<br>
