I've sent in reports earlier about not getting my WMR200 to communicate with weewx (wview works however). Now I changed HW to an Intel G945GSEJT motherboard. Still weewx will not start up:

Now I restarted weewx again but I think it will be the same result again. Just to be sure that the weewx is actually monitoring the USB I pulled the cable and inserted it again:

I (dual) booted Windows Xp on this new HW and Virtual Weather Station has no problem communicating with the WMR200 (there are some link issues with the wind-/outdoortemp meter from time to time but might be related to distance). So I conclude that the USB-communication is working fairly well.
Back to Linux OS. The WMR200 is working with weewx on Raspberry Pi HW/SW but not on Ubuntu 10.04 and Ebox3350/3310 and Intel G945. I can't really figure out what is causing this and I'm too much of a novis to start digging into drivers and Phyton-code.. :-(

First off, thanks a lot for running the tests as that's what makes projects successful is when people contribute.
Second, I only have a raspberry Pi and a Panda board that I've tested. So you are now into additional platforms which will be beneficial to the project.
This is my Panda operating platform:
$ uname -a
Linux panda 3.2.0-1420-omap4 #27-Ubuntu SMP PREEMPT Fri Sep 28 16:21:51 UTC 2012 armv7l armv7l armv7l GNU/Linux
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04.2 LTS
Release: 12.04
Codename: precise
I'm not sure what OS the Ebox3350/3310 and Intel G945 are running
This is the python usb package on the Panda.
$ dpkg -l | grep python | grep usb
ii python-usb 0.4.3-1 USB interface for Python
Overall the problem seems to be that the USB controller on the host recognizes and connects to the USB on the weather console. But the Oregon protocol layer which runs over the USB bus is not completely working. Specifically, the commands being sent by the host to poke the weather console to start providing sensor data across the USB bus.
I do have a 10.04 box I'd have to get working to try to repro this issue, but meanwhile the data you collected is pretty good.
I would like to know the python usb version on those failing machines, and also logs from the previous work where you ran usbmon on the failing machine would be helpful.
My guess is on the failing machines usbmon will show command to the device that are ignored or not acknowledged (nak) for some reason.

Hi again!
First some system information..
The Ebox'en are pretty much the same in SW but some minor differences in HW..
Ebox3310:
Linux ebox3310 2.6.34.10-vortex86-sg #3 Tue Jul 12 02:05:36 CST 2011 i586 GNU/Linux
First some system information..
The Ebox'en are pretty much the same in SW but some minor differences in HW..

I'll include the Raspberry too (that is working fine since a week ago although there was some issues to start with..):

Maybe related but all my "non-working-servers", except the Raspberry which is working with weewx, have pyhon-usb 0.4.2-2. Could this be the cause of weewx not being able to communicate properly with WMR200? Is it upgradeable? The systems are fully up-to-date with apt-get.
If it makes the fault-findning easier/faster, then I can provide access to machine for logs and stuff. I guess it would take me quite a bit longer time to get it all right being a newbie (but I might learn something too..)

I doubt the issues are hardware, as USB is a pretty reliable standard, at least in the ways it's being used here. Plus, the failure would present as "device not found", which is not what is happening.
The obvious correlation is the python-usb version, where it works on 0.4.3-1 and does not on 0.4.2-2.
This can be a misleading hypothesis, however, but may provide a clue.
My ubuntu box has 10.04 and I may be able to try testing, but may be a few days out. I just installed python-usb in anticipation for this test, and it presented 0.4.2-2, so that is the latest for that ubuntu version and not upgradeable beyond that version.
The usbmon data on the python-usb 0.4.2-2 OS'es would be a good log to gather when weewx is trying to startup.
I'm not sure the differences between the 0.4.2-2 and 0.4.3-1. My guess is that once we find the bug, it's a simple fix to get it all working properly.
One required fix for the driver you already discovered is some way to determine the device timeouts as device not there and to abort rather than continuously retry reads that will never complete.

It seems like the problem is solved now but I've done two things:
1. I changed the USB-cable to one with a ferrite core that also loops the cable. Not the original cable but one I found laying around.
2. I set the time/date on the WMR200 from default 2007 to current date. The Virtual Weather Station on XP didn't want to run either and claiming this as a cause "Error on console date". So maybe it is related even on Linux?
