Thanks!


However, since I'm not reading this mail list's posts in detail, I
need a briefing from someone what to be tested:



- software (which version, patch) to compile and which scenario to
run?


I've uploaded

http://www.sax.de/~joerg/avrdude-cvs-20070421.tar.gz

as a bootstrapped distribution file.


- specific hardware, CP210x USB chip?


Anything that uses ser_posix.c.  This would include all USB to RS-232
adapters, i. e. anything that uses /dev/cu* on your system.

Never trust an operating system you don't have sources for. ;-)
