Hi-

I"m new to all this but have been working for a few days trying to get 
weewx working iwth a WMII on a pi b+.  I have done the intall from the root 
cmd prompt following the debian directions and installed the wmII driver in 
the user folder.  I continue to have connectivity issues and errors- 
looking mostly like driver issues maybe?  any help from anyone who has done 
this setup with a WMII would be greatly appreciated, thanks!

Error from the log:
