I have a Prowler weather station connected via USB. Ubuntu does not recognize this. I am wanting to work with the data on the weather station on my computer.
I would assume that the problem lies within 1941:8021 Dream Link USB Missile Launcher.

Could you please assist.

Thank you in advance for any advice that you might have.

Joel

From what I'm reading on the net (via Google) either your weather station is hardcoded with the incorrect USB ID, or the kernel code (or Ubuntu USB database) is miscoded, and that USB ID is being seen as USB Missile Launcher

Chances are good that the thing will not work properly, if at all, unless we can find a patch that fixes the wrong USB ID. Do you happen to have any software for the weather station? Linux software? EDIT - found the software download. (but is it Win or Lin?)

If I find more on this, I'll post it.

PS - Has this weather station ever worked for you on Linux, or is this a first attempt?

Sasha

Thanks for the response.

I did receive software for this application, however it is windows based, but installs very well and works through wine.

The software is called "Easy Weather". Would there be a USB driver located on this CD, and if so, where might I find it?

I originally attempted to try a solution at: https://answers.launchpad.net/ubuntu/+question/97541
but to no luck couldn't figure out a section to work around the USB issue.

This is a first attempt for me and would love to be able to correct the USB issue.

Joel

Glad you got it working with Wine for the time being, as you might have to stick with that if there is no Linux software for the device. I too noticed that the software available online was for Windows only. So, even if the USB ID gets sorted out, there's still the issue of "no software for Linux".

As for USB drivers, for the most part, the Linux kernel has the USB part of it built in; the only condition(s) for the device to work right, is that the USB device ID (abcf:defg) is correctly identified by the kernel, and that the kernel has a driver, if necessary, for the device.

Other threads I have read about this device, which I found by Google, had situations similar to yours: either the USB device was wrongly identified (as a missile launcher) or there was a lack of software to run the device.

I already came across the link you posted above too on the Ubuntu site.
I also came to another thread or mailing list somewhere, where another owner (or maybe you??) of this weather station was in contact with the Linux kernel USB maintainers, and had IIRC filed a bug about the wrong USB ID. I'm not sure what if anything came of that, but you might do some heavy-duty googling to see if you can find this, and if you cannot determine if anything is ongoing with the kernel developers about this, maybe file a bug report of your own, to the USB maintainers.

Sorry I don't really know what to do further, at this point

Sasha

Did this get resolved?

I'm running Ubuntu 10, and trying to connect to a "Scientific Sales" weather station WS1093 (complete with Chinglish manual). I'm trying to get the suggested software (Cumulus) to work with it via Wine. But I'm seeing exactly the same thing -- same manufacturer ID and missile launcher ID.

Hoping one of you guys 3 months ahead of me figured it out!

Unfortunately, I have not found a solution yet for correcting this problem. The only advice was to dual-boot and use Windows to load the weather station device.

Please post if you have any success to let us all know how to fix this issue.

Joel

Hi Joel,

Googling round the Net suggests that 1941:8021 is more common for a weather station than a missile launcher!

http://www.jim-easterbrook.me.uk/weather/ has good links.

The C source code at http://meteolinger.lowlevel.cz/anonsvn/driver/wwsr.c works.

You need to link it with the v0.1 (NOT v1.0) libusb library. e.g.

gcc -o wssr wssr.c /usr/lib/libusb.so

See also http://meteolinger.lowlevel.cz/tracker/wiki

Frank

Thanks Frank for all of the great info.

I still consider myself a bit of a newbie with Ubuntu, though I hate the word.

I've installed GCC and gone to all of the sites, but just can't connect the dots. Could you perhaps fill me in on exactly what you did to get it working, and if you're using Ubuntu/Linux, what weather software you're working with?

Joel

Hi Joel,

The first thing you need to do is to set up permissions so that users can access the Weatherstation USB device (by default, only root can access it).

Create a file called 39-weather.rules in /etc/udev/rules.d containing the line

SYSFS{idProduct}=="8021", SYSFS{idVendor}=="1941", MODE="660", GROUP="plugdev"

To compile any C source to access it, you also need to install the libusb-dev package. Make sure you install that one, NOT libusb-1.0-0-dev.

Then (assuming you have C source in file wwsr.c) you can open a Terminal window, cd to the directory you've got the file in, paste the line

gcc -o wssr wssr.c /usr/lib/libusb.so

into your Terminal window to compile. If you get any error messages, paste them here and I'll explain.

If there's no error messages, then you can run the program by typing

./wssr

in the Terminal window.

./wssr -a

will display current weather readings.

If you still can't get it to run, and you're running Ubuntu on a 32-bit system, I can send you my executable.

http://forum.pendec.dk/ is a very useful site... sign up there and read the Weatherstation forum... I've put my C source code there.

If you prefer Python, then the pywws Google group is for you. http://code.google.com/p/pywws/

Hi Frank,

Here is how far I've gotten.

Hi Frank,

Ok. I worked with my partner a bit with this again and here's what I've managed. Still not working, but a tiny bit further.

joel@joel-laptop:~$ cd /etc/udev
joel@joel-laptop:/etc/udev$ ls
rules.d udev.conf
joel@joel-laptop:/etc/udev$ cd rules.d
joel@joel-laptop:/etc/udev/rules.d$ ls
39-weather.rules 70-persistent-net.rules README
70-persistent-cd.rules 90-r5u87x-loader.rules
joel@joel-laptop:/etc/udev/rules.d$ cat 39-weather.rules
SYSFS{idProduct}=="8021", SYSFS{idVendor}=="1941", MODE="660", GROUP="plugdev"
joel@joel-laptop:/etc/udev/rules.d$ gcc -o wssr wssr.c /usr/lib/libusb.so
gcc: wssr.c: No such file or directory
joel@joel-laptop:/etc/udev/rules.d$

I do have libusb-dev installed. The versions I had the option to install were 1.0 and 2:0.1.12-14. I installed the 2:0.1.12.14, not the 1.0 version.

Joel

You are all most there.. you will just need to copy the wssr.c C source code to your home directory before compiling.

Goto:
Download the file to your home directory and compile it as said above

Hi again Jvan,

It's hard to know just how much a "newbie" (sorry) someone is, so I left out some steps.

First, make sure that you have installed the the libusb library. I did this using the "Synaptic Package Manager"... go to the System menu, choose Applications, then choose Synaptic Package Manager. Put in your 'root' password.

Search for "libusb-0.1" (without the quotes). If it's not already installed (the square is green), then install it.

You need to download the file http://meteolinger.lowlevel.cz/anonsvn/driver/wwsr.c -- probably it will automatically go into your Downloads directory, so you should move it to somewhere more appropriate... I suggest creating a weather directory, and moving it there, as follows

cd ~
mkdir weather
cd weather
cp ~/Downloads/wwsr.c .
gcc -o wssr wssr.c /usr/lib/libusb.so

You should now find a file called wssr in the 'weather' directory. Type

~/weather/wssr

to run it. It will show a help listing. Type

~/weather/wssr -a

to get weather details.

Ok, thanks for the help.

Now, I've got the weather information showing up in the terminal, however how do I get it to work with weather software? and do you suggest any software that works well with Ubuntu?

Joel

My device is the one featured here (http://www.maplin.co.uk/module.aspx?moduleno=223254) "USB Wireless Weather Forecaster". It's got "Weather Station - Model: WH1081" on the back...

Prior to installation, I ran "update-usbids" to make sure I have the latest available info.

The following is seen in /var/log/messages upon USB device insertion: -
kernel: [634601.160205] usb 1-4.2.2: new low speed USB device using ehci_hcd and address 8

# lsusb | grep 1941
Bus 001 Device 008: ID 1941:8021 Dream Link USB Missile Launcher

The provided software "EasyWeather" (http://proweatherstation.com/easywea...asyweather.htm) and the oft-recommended software "Cumulus" (http://sandaysoft.com/products/cumulus) both seem to work perfectly within "wine" on my Ubuntu 10.4 Linux and it seems a shame that I can not link the software to the USB device...

Any help or advice would be greatly appreciated!
