[Olivier GARNIER]

Hi,

I'm trying to read/write on usb weather station.
I've got a C soft which find it on /dev/uhid0

But i do not know how to read/write on it.
It make 5 years i've not used C developpement.
I've read handbook and what i can find about USB / UHID and 
communication ...
But i still don't know how to read and write on it.

Can someont tell me where to find an example or who can help me ?

Thanks,

Olivier
