Hello Arnaud, thanks for the effort for the patch!

I'm not sure that everything is ok. If I run the driver as "./bcmxcp_usb -u root -a ups" it launches, but after a second I get a "Communications with UPS lost: get_answer: not the right sequence received 0!!!". However the driver seems still to keep running. I also tried to start the driver under debug (-DDDD). In attachment you can see the output (until I typed ctrl-c), that also include some some of the 'communication lost' messages. Cheers, Massimo
