vp2 usb driver update

This does not appear to be new… Please see:

Sorry, didn’t see this thread, I posted in another section & a moderator must have moved it over here. Working flawlessly for me, so far. Definitly an improvent over v4.4 for me.

Running solid for 9 days now without a hitch. The new driver is working great for me.

I could not get it stable under Vista, it locked up after one day.

Mine has been running about 100 days straight, without a single error. PC has never even been rebooted, not once in all that time. So it must be machine specific. My Vista is fairly clean, on a dedicated laptop.

i did see a report that it could be things like flourescent light bulbs that cause problems with the usb connection even…which is why replacing the mini USB cable with one with RF chokes at each end has helped out

:lol:
Hi All,
Been running for a week now with the new driver, no blue screen, no dropping the link etc… this is good

Also Running Win XP SP2

:salute: :salute:

Followup

I had problems when ver. 5 first came out blue screen and lockup. I think there was a problem with ver 4 and ver 5 on my machine at the same time. When I installed ver.5 I though it would remove ver.4, it did not. so I removed ver.5 everything worked. This time I removed everthing with device manager for ver.4 and re downloaded ver 5 and installed it. Everthing has been working good for about 60 days. Joe

I also had the USB disconnect/lockup problem. I called Davis and they exchanged my USB with a serial version. Works without a problem.

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.

Automan.

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

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.

CP210x Windows Driver v5.2.1 - January 30, 2008

May try this driver when my copy of Windows Home Server arrives :slight_smile:

Automan.

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.
