vp2 usb driver update
« 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.

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.

New USB driver for Davis VP2 - v5.0
« Reply #5 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.

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