Hi there, Sakis3G works fine on Raspberry but on Udoo there seems to be a driver problem. The kernel versions differ also but I cannot find any hint what the root cause is. I posted this question on Raspian and they referred me to Udoo, but they supposed also its a kernel problem and provided some good hints but I'm no further. Has anyone got Sakis3G working on Udoo and what one needs doing getting it working? Can one use the Raspian kernel source and build a Udoo kernel? Thanks, tranner
