OK, looks like there was as well a problem with the (custom, not ubuntu
related) program setting up the serial port under certain circumstances - with
the fix for this bug and a fix of the custom program, my FHZ 1300 PC device now
works correctly with /Ubuntu 2.6.35-25.44-generic 2.6.35.10/ as
No further problems here, so it seems it is fixed for me. Thanks!

After watching waiting a bit, I've seen no more errors of the type I
described in #16. I've rebooted and done a replugging test or two and
it's all been solid.
Coincidentally one of my 1-wire sensors died but I got quite different
error messages from that and it seems clear that the ftdi_sio
Unfortunately the fix seems to be incomplete for me.

Hm. The changelog in the package I installed (linux-
image-2.6.32-28-generic 2.6.32-28.55) shows this:

well, this does not work in Maveric with /Ubuntu 2.6.35-25.44-generic
2.6.35.10/ either
- the Unable to write latency timer: -32 error from dmesg is gone now, but
the port seem to hang after a few commands are send through successfully and
only a reboot brings it back to life - though again
This bug was fixed in the package linux - 2.6.35-25.44

This patch was applied to Maverick as part of an upstream stable update,
therefore it doesn't require individual verification.

Just to be clear, 677aeafe19e88c282af74564048243ccabb1c590 is NOT in the
lucid kernel, while 6a1a82df91fa0eb1cc76069a9efe5714d087eccd is. So
lucid is carrying a patch that has been reverted upstream and as
described, changes the kernel back to the previous way of working. Git

Thanks for the additional info Alex and Aleksandr.
Have sent an email to kernel-t...@lists.ubuntu.com recommending this
patch also be applied (thus removing the change) for both lucid and
maverick. Will see how we go.

Had a look at this bug prompted by a request from Alex as I've had some
modest experience with Arduino devices and USB serial interfaces as
well, albiet a long time ago. I _do_not_ consider myself expert in
either however! :)

This is the code that gets loaded onto the arduino.
The reporter says that a basic hello world arduino program might be
sufficient to prove breakage too, as long as the hello world does both
input and output.
