Ok. :-) finaly we found at least one channel to communicate.
So I only use linux-usb-devel for further communication.

Hardware industries are not always as honest as we are used to be. 
So we've got to develop our test methods ourselves. 

--------
So I suggest:
--------
a drop in IDE communication of about, well, more than 6MB/sec is
a clear sign for a buggy (in our sense) hardware.
(just simply try out 
hdparm -t /dev/<device>
before and after using and unloading ehci-hcd)
--------

So we have to do sth. against this situation.
First in my thought comes a problem about bugs in the 
american rights system: DMCA

I can't imagine that only VIA is doing such things. Our vision is not to blame 
one single company. So we have to find a general way of talking about the 
problem:


green: everything is working as expected (in our sense, without a drop in ide 
transfer rate)

yellow:  device is working as expected, altough a ide transfer is failing our 
6MB/sec transfer rate expectations. IDE transfer rate are reduced for more 
than 6MB/sec while we are using ehci-hcd. When unloading ehci-hcd the win in 
tranfer-capacity is mor than 6MB/sec. (use hdparm -t /dev/<device> for 
measurement)

orange:  some (maybe more than one) device is not working as expected, but 
other devices work as expected. Others don't. This is nice because at least
a part of your computer is working as expected. This is a big achievement
today :-)


red: ok. this is worst case. nothing is working as expected. when i say 
nothing a mean nothing. so a realy bad situation. 

-----------


so for example my case of problem is orange: my usb-storage devices are
working as expected. One or more devices are not workin as expeced. (not so 
nice but better than nothing :-)


so is this a bit of over-reaction or appropriate?


Cheers 
helmut
