Can you generate a log where bytes are actually lost? Nothing seemed to
get lost in the previous log you posted.

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
