My machine since running my new Davis has had 3 x BSOD's

Microsoft Crash Debug analyser says probable cause all three times is silabser.sys which is part of this package.

I have v5.1 and will now try an older version.

EDIT:
Using VPort Beta so will try other version 1.1.2 as it is the program making use of that port before playing with USB drivers.

Machine went for about 36hrs and did it again BSOD :(

I am now trying the 4.40 drivers posted on the davisnet website to see if that helps.

Personally I am absolutely convinced that my USB lock up problem is caused by electrical interference from something else in the house.  My station ( Davis VP2 ) is at a second home and whilst there's no-one there it works perfectly but I just visited for 5 days and it crashed twice; previous to that it has worked without a hitch since our last major visit in September.

There are a number of posts on here suggesting the same thing. Have you tried a good USB cable with ferrites on it? (Looks like a snake that had a big lunch.)

Yes, I would say it is electrical interference that is the one of the causes
which explains why some people have a problem and others do not
Someone needs to tell Davis about this.

 New question to thread

I am getting ready to Up Grade to a Davis system from my Lacrosse

My Lacrosse uses a serial Port for computer Data

The Davis offers both. Just looking for feedback as to a usb or serial connection?

Thanks

Brad

Get the serial, you then have 0% possibility of having the USB issues that have been experienced by a small percentage of USB owners.

Hi Niko,

Yes tried the snake thing and to be honest it did seem to improve the situation; I fitted it at the same time as I relocated the PC to a different part of the house ( because we don't have elecrical ring mains in France I decided to connect the PC to a different electrical spur to the weather station ) so I'm not sure which one has actually improved the situation.  I also installed " logmein " on the computer so that I could remotely set it if it crashes whilst I am away but so far I have only had to use it once to do this in about 5 months; the main problem is as I said when I'm actually at the house ( when there's obviously much increased electrical activity )  but it's not as bad now as it used to be prior to ferrite cores / relocating.

I was having a rash of lockups with both VWS and WD under VirtualVP, first with driver version 4.4 and later with version 5.1.  In desperation I searched and found this latest version (5.2.1), installed it, and haven't had a single lockup since.

Don't know it is the answer for everyone, but it sure worked for me.

VirtualVP has an option that if enabled will cause VirtualVP to reset the Davis/SiLabs USB driver when it detects that communications have been lost. Did you have that option enabled? I know that has solved the USB problem for many people.

Yup.  Tried that; it didn't help.  My problem was that Windows would blue-screen and reboot with a USB driver error.  Since I updated to the V5.2.1, I've had no problems.  All is well for me, now, at least so far.

My 30-day trial for VirtualVP is almost up.  Guess it's time to purchase.  I'll likely get the startup app (whatever it's called) as well.

Bluescreen!!! Not much VirtualVP can do for that! I've heard of problems with the USB drivers, but nothing that severe.

No, I never thought it was VirtualVP that was the problem, but rather the USB drivers themselves.  I had the same errors without VVP running and with either VWS, WD, or VPLive straight to the com port.  I knew it wasn't your apps causing the issue.  I'm running off an IBM T40 Series laptop through a docking station with quite a few USB devices.  I suspected a driver conflict somewhere.

Nevertheless, since upgrading to V5.2.1, which has been at least three weeks ago, I've had no problem.

I'm most anxious to get the weather station and apps off my laptop and onto a dedicated box; thus my interest in the appliance solution you are investigating.

I'm in the process of ordering the parts for the first batch. The tests went well. Even with a USB pen drive and a web cam drawing power from it, it's still running 5 to 6 watts (mostly 5). My computer that is currently running my weather software (and will get that moved off to this new box) draws 3 times that much power WHEN IT'S TURNED OFF!!! It will be nice to turn that monster off when I'm not sitting in front of it. And I'll be turning it off with the rocker switch on the power strip.
