If an OFW hacker shows some interest, they'd say what to try. We've tweaked OFW USB and SD timings before to handle marginal or out of spec devices before :-/ >.

Right. Though what I am trying to say is that SD card reliability (across s/r cycles) is achievable, USB not so much. cheers, m -- [email protected] [email protected] -- Software Architect - OLPC - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
