Alan, looks like we are not quite there yet, just tried a fresh 3.8.3
build with both of your patches and here is what I have -

[ 7.798332] usb 1-2.2: USB disconnect, device number 3

So half of them is gone, just those remained. I downgraded to systemd
197 for the build just to make sure.
Those -19 and "unable to enumerate" messages aren't necessary; I'll
send you an updated version of the second patch that will get rid of
them. However, the "USB disconnect" messages are unavoidable.
Here's the updated version of the second patch.
You know, these patches probably will apply okay (or with only minor
changes) to 3.9. Then you should be able to use any config setup you
want.

Alan, thank you very much for your effort! The updated second patch did
resolve all the remaining errors.
In case you have any questions or need assistance or anything of this
sort, feel free to contact me, I'll be happy to help.
Remember I mentioned a friend of mine, that I sent your first patch to?
Well, she tried it on an amd system with 3.8 and nvidia nforce chipset
and though her usb hub error messages disappeared, her system was unable
to auto-detect new devices after the patch.
Meanwhile, I convinced her to go with 3.9 + the special build config we
successfully tested and so far all seems to be almost perfect.
I'm not sure if sending her the second patch will help.
So this is where we stand... If you wish I can suggest her to contact you.
