I connected two pls2302 usb-serial converters to two different

Terminal1:
cat /dev/ttyUSB1
Terminal2:
while true; do echo 123456789012345678901234567890 > /dev/ttyUSB0 ; done
cat and echo are known to not work well with usb to serial devices. Can
you duplicate this with a "real" tty program like minicom or something
else?
I will try to set up a test use-case which uses kermit.
But there is a calltrace in kernel log when using cat & echo, so
something in the driver went wrong.
Thus there is a bug which can be reproduced and it should be fixed,
don't you agree?
best regards,
