The logs look incomplete. It's probably because they're flooded with serial_write_room and chars_in_buffer messages.
Hmmm - i feared that this happens - the logs where to big.
Can you try to reproduce this on a later kernel (e.g. 3.8) which uses dynamic debugging?
I will try to compile a kernel 3.8.5 like this way: http://verahill.blogspot.de/2013/02/342-compiling-kernel-38-on-debian.html But this will take some time ...
Can you minimise your test setup using a custom program which only opens the device, initialises it, writes the four characters (e.g. "test") and reads them back (over you hardwired loop) before closing the device again?
I have used a little perl program that opens the port and send "Test" to the looped back device. The length of the log looks good.
Make sure to verify it using a working device first.
I use this script with a ch341 adapter and it works.
Thanks, Johan
