I have a vp2 console with the USB 6510 logger interfaced into a DIR 505 mini router running meteobridge. When it works it's great! However, it goes offline at least once a day maybe more. When I go to the router the little light on the passive USB hub is dark. Sometimes if I just pull it out and re-insert it into the 505 it will light and pick up. Sometimes, though, I have to reboot the router for it to light and pick up the console again. I suspect it's due to the cheap no-name USB hub I am using. If those of you using meteobridge on hardware requiring a USB hub to interface to your Davis console could enlighten me on models which work, I would be most appreciative ! I found a powered hub and put that inline for now, we'll see if that stays up or not, as I'm approaching the 12 hour mark without it going down. It could of course be the USB port on the little 505 as well but I need to eliminate the hub as the issue. Would obviously prefer a passive hub that works rather than having one more thing needing to be plugged into power. Thanks ! Joe
