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?
