I thought I might do an update on the Davis USB logger.  I read many threads about the difficulty a lot of people were having with lock up when using the USB data logger.  I did get a new Davis Vantage Pro2 with the usb logger.  I installed it on a new HP X18-102us laptop running Vista 64 bit and it has so far been running flawlessly for 7 days.  I am hoping that Davis may have worked the bugs out of the USB logger.  I installed Weather Link 5.8.1 and Virtual Weather Internet.  If I do run into some of the same issues I will post the results.

Just reporting some anecdotal bits to suggest that the USB issue has not gone away with a new Davis Vantage Pro and Weatherlink 5.8.1 - out of the box.  Not asking for help at this time - I have now read all the USB hints here and will try them out when able to next trek out to my remote station.

Just bought a new Davis Vantage Pro (wireless) with 6510 USB data logger from Ambient.  Worked without fail for two weeks, 24/7, in my backyard while using Meteohub/Weatherhub as the USB and Internet interface between the station console and www.wunderground.com.  Since I was using the Meteohub I did not need to use the Weatherlink software.

I then moved the rig to my remote location.  Once there a power failure revealed that the Meteohub solution was not going to work as the Meteohub does not automatically restart itself after power failure - gotta manually press a button on the front of the device.  Thought briefly about just adding a UPS but then another issue surfaced with the Meteohub approach and I decided to dump it and change over to using a PC 24/7.  Set up a brand new Windows Vista (32 bit) machine, installed WeatherLink 5.8.1, and opened up a good book.  Three hours later the USB connection to the console hung/dropped.  Pulled the plug, put it back in and all was well - for four hours.  Over the next 24 hours, the USB connection dropped every three to five hours.  Was always correctable by simply pulling the USB plug and reinserting it.  OK - I figured probably a Vista thing.  So I pulled a dependable, two year old Windows XP Home Edition PC notebook out of the trunk of the car and set it up.  Worked fine for two days and I went home happy except for missing my favorite notebook PC.  A day and a half later, the USB dropped.  A neighbor reset the PC for me and data flowed for maybe 18 hours before stopping again.  I don't want to bother the neighbor again so the next round of experiments will have to wait until I can travel to the remote location.

Throughout the adventures above, a Panasonic IP network camera (connected to the router by ethernet) chugged along without incident, cheerfully uploading its view once per minute.

Best regards, Major H, MajorH@satx.rr.com.

I know you've now dropped the Meteohub idea, but had you seen these

ideas for auto-starting an NSLU2 on power restore? All unofficial and likely to affect warranty...

I had not seen those items on the Meteohub.  Thanks.

I should also have mentioned that within the last couple of weeks the Meteohub software has also become available for hardware other than the NSLU2, including 'generic x86' and a VMware virtual machine. At least some of the other hardware does do auto-on.

You are probably aware of this, but maybe others aren't so lest anyone should think I'm directing anyone away from WD with my Meteohub talk I'll point out that WD can still be very relevant even with Meteohub involved, since data can be pulled from Meteohub into WD either via export as 'logfiles' or via the 'logging protocol' (which is what I use) to gain access to the vast array of features  that WD offers.

If pulling in large (days or months worth) of backlogged data, the logfile route is probably more efficient, if pulling in data from overnight or a WD PC power failure then the logging protocol is better. For pulling in live data the logging protocol is the obvious choice.

Hi all. All week has now gone by since installing the serial data logger without one glitch let alone a crash. So to anyone out there contemplating buying a Davis VP system, follow Brian's advise and order a serial data logger. It will save an awful lot of time & head scratching.

Thanks to everyone for all your help. :D
Cheers,Simon

Follow up on my last post in this subject, which was August 7, 08....

I have had NO data logger issues, no random lockups since switching to the serial data logger which Davis provided.  It certainly seems it was the USB.

Just an update.

I must be one of the lucky ones. I have and use a USB logger.  For two years now it has been running without a single lockup.  And it has been on two different computers.

6 weeks now with the serial data logger & not one hitch. It is interesting to note the Campbell Scientific don't even mention USB.

Just to make it clear because this is a long thread now, you previously had problems with the USB and swapped to Serial - is that right?

Could it be linked to what chip your USB is using?

I went with a USB logger and its been running since about 12/25.  My machine randomly looses connection (2x today).  I ordered WL-IP so I hope I am able to stay connected once I set it up.
