Re: Testing for hardware bug in EHCI controllers

Hello again Alan, we read that the patch broke. Damn, our fear was
justified. If we are right, it will break again because it affects
various
devices using different busses, each one with its limitations and
defects. That's why we wrote to Sarah(and got no reply yet) that
vendors
should fix their h/w bugs in-house or give open source developers full
documentation (like nda datasheets,bios spec,bios spec up)
to cope with their >buggy< hardware!

Since something is broken and the last program tested exits at A50M,
we have some questions for today prior testing A50M, moschip and
ICH4M:

1)Do we need to apply a third
patch(http://marc.info/?l=linux-usb&m=136379040918329&w=2) [it's upper
part to be specific]? If yes, please make
a cumulative patch for 3.8 series before we mess things up and post it
under this subject. At the same post, add the final test program with
program version number printing as well as a "do NOT unplug the usb
and a leave the program to go up to 1000" message. Also point out that
the
device must not be inside the unusual devs file as you told us. This
will make it easier for others to follow and help you.

2)If A50M still fails, do you have time to analyze our usbmon output?

3)Has any type of transfer corruption been observed from this bug?
