Hi all,

maybe someone has a idea and can explain why the data - download is not working ? 

I started like the description below :

3) i downloaded the file ( fowsr-1.0-20110904.tar.gz 36.0 KB ) & found this :

4) now i started " make " and got this :
-------------------------------------

5) There are now two (2) new files in the folder :
--------------------------------------------------
-rwxr-xr-x 1 root root 23683 31. Aug 13:17 fowsr
-rw-r--r-- 1 root root 20768 31. Aug 13:17 fowsr.o

6) i start the program without any options and get this :
---------------------------------------------------------

root@brenner:/home/internet/Download/Wetter-Station-Proggi/fowsr-1.0#

. . . . .

But it´s a empty file, no data and i have made ALL by root, who can write everywhere ! 

So now i do not know what i can do to get it working :-(

Who has a idea, or can tell me what was going wrong ?

Thanks in  advance

Maybe some more information ? : 

The kernel told me this :

But even as at my first post, i am no programmer and so i do not know if this helps . . . .? 

Maybe somebody else can understand what´s going wrong ? 

Thanks

And once more hi to all,

as DOUG as posted, i took a look to my fowsr.c file and made a egrep and found this :

# egrep 'product*' fowsr.c
struct usb_device *find_device(int vendor, int product) {
&& dev->descriptor.idProduct == product)
int CUSB_Open(int vendor, int product)
dev = find_device(vendor, product);
int product = 0x8021;
CUSB_Open(vendor, product);

even a egrep for " vendor " gave me this result : 

# egrep 'vendor*' fowsr.c
struct usb_device *find_device(int vendor, int product) {
if (dev->descriptor.idVendor == vendor
int CUSB_Open(int vendor, int product)
dev = find_device(vendor, product);
int vendor = 0x1941;
CUSB_Open(vendor, product);

This is the same what - lsusb - tells me :

-----------------------------------------------------------

# lsusb

. . . . 

Bus 001 Device 003: ID 1941:8021 Dream Link WH1080 Weather Station / USB Missile Launcher
Bus 001 Device 002: ID 04b4:6560 Cypress Semiconductor Corp. CY7C65640 USB-2.0 "TetraHub"

. . . . . 

Next i changed the place for the output from - //var to : //var//log//fowsr// as you see : 

------------------------------------------------------------------------------------------------------------------------

# egrep '//var' fowsr.c
char fname[] = "//var//log//fowsr//fowsr.dat"; // cache file
CWF_Write('p',"//var//log//fowsr//pywws.log");
CWF_Write('s',"//var//log//fowsr//pwsweather.log");
CWF_Write('w',"//var//log//fowsr//wunderground.log");
CWF_Write('x',"//var//log//fowsr//fowsr.xml");

I made a empty file by using :

------------------------------------------

root@brenner:/var/log/fowsr# ls -l
insgesamt 0
-rw-r--r-- 1 root root 0 2. Sep 15:14 fowsr.dat
root@brenner:/var/log/fowsr#

Last i changed as DOUG has written the debug level from 255 to 1 : 

-------------------------------------------------------------------------------------------------

/***** The CUSB class *****/

int CUSB_Open(int vendor, int product)
{
int ret;
char buf[1000];

usb_init();
usb_set_debug(1);
usb_find_busses();
usb_find_devices();

dev = find_device(vendor, product);
assert(dev);

devh = usb_open(dev);
assert(devh);

After this i tried a new compile with this result : 

--------------------------------------------------------------------

# make
gcc -c -o fowsr.o fowsr.c
gcc -lusb -lm -o fowsr fowsr.o

root@brenner:/home/internet/tmp/fowsr-1.0#

As you see, there is the same problem as before : 

------------------------------------------------------------------------

root@brenner:/home/internet/tmp/fowsr-1.0# ./fowsr
0805D840 | 00 00 00 00 __ __ __ __ __ __ __ __ __ __ __ __ | ....
usb_set_debug: Setting debugging level to 1 (on)
usb_get_driver_np returned -61
0805D844 | 00 00 00 00 __ __ __ __ __ __ __ __ __ __ __ __ | ....

failed to release interface: 0
failed to close interface: 0

root@brenner:/home/internet/tmp/fowsr-1.0#

So now i really do not know what i can do to get this - fowsr - working :-( 

Who has a idea, or can explain me what i can try ? - Thanks

Did you try a 'fowsr -r'  or  -b or -d

They should return data from your weather station to the screen. From what I see there are no serious error messages. You can ignore the release and close messages at the end.  My guess from what I experienced here is that it is working. Tell us what you see when you do  the -r  or -b or -d ?  This display a memory position followed by a bunch of data. It won't make any sense but if it is there I think you are working.  If so then try  foswr -x  or -w   and it should make a log file in the directory you selected.  /var/log/fowsr.     I think you said you created the fowsr directory under log. If not you need to. Also I am running here as root.

Some issue here, my be I have not understand we'll watch I have to do, my English is not so good...
It seems that at the and Doug has been successfully in connecting his station but how?

I have understand that the error message is not so important if with fowsr-d I have the return of data in my ws 1080 and so it is for me.
It looks that the real trouble is the invoice of data to the wunderground account but watch solve it ?

Thanks very much and excuse me again for bad english
