Hi Greg, In v 2.6.12 , whether routing Kernel debug messages was enabled ? Or it was enabled in the later versions? I did all the configurations even then i could not get the dubug messages on USB -serial. Even if I commneted console=ttyS0 and wrote console=ttyUSB0, all the logs are routed to ttyS0... Do you have any comments on this .. Please have your words ..
