Hello mashi (Mashi is the kichwa word for friend, partner, associate, 
camerade. Kichwa is the language spoken in the Andes mountain region 
along all the West of South America).

I am trying to lo use Broadcom wireless device on GuixSD. It is 
confirmed to work with free drivers and free firmware. It works 
correctly in Trisquel too.

dmesg gives the following messages. I have included only the relevant 
parts:
