Sorry about the long delay.
I have the log file, as suggested.
bperk|16% modprobe pl2303 debug=1
bperk|16% perl -e ' open(IN, "</dev/ttyUSB0");open(OUT, ">/dev/ttyUSB0");print OUT "foo\n"; $_=<IN>; print $_;'
oo
Here's the log file: http://netspace.org/~bperkins/pl2303bad.text
I also managed to get it to work once also (it printed out "foo" correctly)
Here's the log file for that: http://netspace.org/~bperkins/pl2303bad.text
And perhaps, more usefully the diff: http://netspace.org/~bperkins/pl2303diff.text
which seems closer to the realm of readable.

I'm running 2.6.10-rc1, and I'm having trouble with the PL2303 driver.
Can you try 2.6.10-rc2 and let us know if you still have the same problems there?
I tried rc2, and the pl2303 problems seemed to be the same.
Can you enable debugging in the module with either: modprobe pl2303 debug=1 or after the module is loaded: echo 1 > /sys/module/pl2303/paramaters/debug
and then send us the syslog output when you send and receive data and think you are loosing characters?
thanks,
