Can you generate a log where bytes are actually lost? Nothing seemed to get lost in the previous log you posted.
This was a log with lost data. The logs seems to make politics. ;-)
How can i enable the debugging in kernel 3.8.5?Make sure debugfs is mounted: mount -t debugfs none /sys/kernel/debug and then enable debugging: echo "module usbserial +p">/sys/kernel/debug/dynamic_debug/control echo "module pl2303 +p">/sys/kernel/debug/dynamic_debug/control Johan
