Title: vp2 usb driver update
Post by: dave7101 on August 01, 2007, 06:32:28 PM
I upgraded to the USB v5.0 driver found here

Driver: CP210x_VCP_Win2K_XP.exe (= VCP Driver Kit)

http://www.silabs.com/tgwWebApp/public/web_content/products/Microcontrollers/USB/en/mcu_vcp.htm

and it works flawlessly, perhaps a fix once and for all, for the davis vp2 usb hang/disconnect issue.


Using XP Pro SP2

Hi Dave,

I'll give this a try; lots of problems with my USB logger suddenly stopping sending data to WD.  Let me know if you encounter any future problems with the patch and I'll do likewise.

Cheers,

Steve

This driver causes a Blue Screen of Death on some systems. I suggest you avoid it for the moment or be prepared for possible data loss and corruption!

Not only does the V5 driver cause lock up problems my AVG anti-virus scanner has shown a number of Trojans associated with the install. Not sure if they are false positives but worth running a check if you have installed this.

Title: New USB driver for Davis VP2 - v5.0
Post by: Tlowe on September 25, 2007, 07:25:31 PM
There is a new USB driver available for the VP2 from Silicon Labs. This version (5.0) seems to work much better than 4.4. WD has not hung up since I installed. Mine was hanging  everyday previous to this version. Davis told me thay would swap my USB logger for a serial if I continued to have problems with this driver. I'm running Vista Home Premium.

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.

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

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.

Title: Another BSOD
Post by: Automan on January 07, 2008, 08:23:05 AM
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.)
Title: Re: vp2 usb driver update
Post by: Weather Display on January 07, 2008, 08:39:47 PM
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

Post by: niko on January 08, 2008, 04:08:45 AM
Get the serial, you then have 0% possibility of having the USB issues that have been experienced by a small percentage of USB owners.
Title: Re: vp2 usb driver update
Post by: Tayac on January 08, 2008, 08:50:45 AM
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.

I had the 5.1 drivers make my XP Pro machine BSOD several times.
The Microsoft Debug Crash Analyser always listed the USB device driver used by CP210x as the cause.

Been okay however for several weeks on V4.40 from davisnet.

Title: vp2 usb driver update - optional alternative
Post by: Ann Brush on December 17, 2008, 08:52:52 PM
Just a FYI. I have a laptop (IBM Thinkpad) that acts ONLY to operate my Davis VP2 system (Weather link, Ambients weather software for web uploading (cant remember name)). Updates to the net (CWOP and Wunderground) 24/7/365. The computer has no serial port only USB's. I bought a standalone serial I/O adapter to USB cable converter thingy with its own software driver as a standalone unit from a third party vendor. I connected my Serial Davis data logger (Weather Link) to this dummy serial interface and connected it to the virtual COM1 port (created by the USB to serial driver software). Turned off windows updates and the unit has operated flawlessly for 6 months without problems. There was one 5 day period where it shut down due to windows updates doing a restart and requiring a password but other than that I forget the computer is even there, with windows updates turned off, the computer gathers dust operating under my office desk. This has been a great solution.

the problem is not though with the serial data logger like you have
its with the usb data logger

Ok...i'm having this problem as well...but the 5.2.1 driver does not appear to be available anywhere....does anyone have a link or copy of the 5.2.1 driver? I tried the current 5.4, but it still crashes my system.

I was running fine for the last 2 years until I mistakenly upgraded to the weatherlink 5.8.3 last week from version 5.7

Hi

Im currently running Silicon Labs CP210x USB to UART Bridge version 6.3.0.0 and have tried to update my driver to latest version 6.5 from this link:

http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

It seems to go well updating the driver - but the version still says 6.3.0.0 - see attached.

Anyone running with latest version 6.5? If yes - how did you update the driver?

Best regards,

Henrik
Title: Re: vp2 usb driver update

Hi Brian

Thanks - I found the link:

http://www.weather-watch.com/smf/index.php/topic,52986.msg427318.html#msg427318

I just needed to uninstall the old driver, restart and install new driver. Now im running latest version (6.5)

Best regards,

I had that same problem again recently when trying to update from v6.4 to v6.5.
I don't know why it is such a faff and it is more annoying that the SiLabs driver installer reports the update is successful when it isn't - caught me out big time as you can see in that thread link.
