I've also tried the gnew-sense (metad) linux kernel with the same result: % uname -a Linux mini-0 2.6.37-libre-lemote #1 PREEMPT Thu Jan 6 11:56:46 UTC 2011 mips64 GNU/Linux Unfortunately it didn't work either, :-( So it might be that the USB controller is buggy? Any ways, just wanted to report in case someone might ggest that... Any suggestions are welcome... Thanks, -- Javier. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
