Bug#704242: Driver for PL-2303 HX not working
Hi Johan,

This was a log with lost data.
The logs seems to make politics. ;-)
Then the problem is most likely not in the driver as the characters are
being read back in the log you provided.
Stop - it's really possible that i send not enough bytes.
Sometimes up to 6 Bytes will come back.
This time i send this string (3.2.0):
"1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890\n"
I get back the first 3 Bytes of it.
Log is attached.
Before closing the connection Perl sends a 'stty -aF /dev/ttyUSB0' and prints the result:
speed 9600 baud; rows 0; columns 0; line = 0;
intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>;
eol2 = <undef>; swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R;
werase = ^W; lnext = ^V; flush = ^O; min = 0; time = 16;

echoctl echoke
canonical-mode is not enabled and I get back 3 bytes - so data is not lost complete.
With cutecom it's -icanon also. So everything should be fine.
There are 2 beasty questions left:
1. Why it works with PL2303H ?
2. Why i receive sometimes the first bytes?
Now that you have compiled your own kernel, you could run a git bisect
to learn if anything else has changed in the kernel (possibly
interacting with your test setup) which can explain why things
stopped working.
I learned much in kernel testing the last time ... :-)
Maybe there is a HowTo for the bisect testing?
Your kernel is not configured to use dynamic debugging. You need to
enable CONFIG_DYNAMIC_DEBUG=y.
Oh - then i must compile again.
I found
# CONFIG_DYNAMIC_DEBUG is not set
in .config.
