Please send the patch above for inclusion in 2.6.15.
Thanks for your help!
Unfortunately that patch is not suitable for the kernel. Below is another
patch that _is_ suitable. If this one works as well as the other (be sure
to remove the previous patch before testing!), I will submit it for
inclusion.
I can suspend and resume successfully using your latest patch. Previous
patch had been reversed prior to the test as you suggested.
However it's probably too late for this to go into 2.6.15 -- more likely
it won't appear until 2.6.16.
That's unfortunate. With either of your patches, suspend worked again for
me. May I ask you to try to submit your patch anyway, perhaps it will end
up in 2.6.15 (and I'd be happy).
dmesg excerpt follows:

One question remains: Is the USB disconnect after resume expected and
if so, is there any functional difference between the two patches?
Thanks for your help!
