Hello together,
i will close this bug at Debian now.
After the last update this error seems to disappear in Debian stable.
http://ftp.debian.org/debian/dists/wheezy/ChangeLog
USB: pl2303: fix device initialisation at open
The source for this patch can be found here:
http://www.spinics.net/lists/stable/msg30311.html
It's possible that this will not fix the bug under all circumstances depending on the application.
Summary:
======
I did need some time to realize that this bug will occur only with PL2303HX chips that are China clones.
In fact this type of chips run out of production at Profilic.
http://www.prolific.com.tw/US/ShowProduct.aspx?pcid=41&showlevel=0017-0037-0041
Only the PL2303HXD can be buyed as original, so any new PL2303HX is a China clone.
I have been contacted by Frank Schäfer and so we tested some of his driver improvements in combination with newer kernels.
Up to now this could not be backported to kernel 3.2.x, but i could test a kernel 3.12.6 on Debian wheezy and the
PL2303HX is running fine.
There are really much products with this clone chips out there, so some further improvements of the driver would be
really helpful.
I will make further tests together with Frank and hope that this improvements will find a place into the next kernel
versions starting with Debian jessie and 3.12.6
Best regards
Karsten
