I just tried to backport the hub_reset() and persistent_device() functions from hub.c in 2.6.26, but it didn't help. (So the patch I attach to this comment DOESN'T WORK).

I guess there are also modifications in the ehci driver but I'm not fit enought to look in it.

I searched throught the diff file and through the changelogs of the vanilla kernel, but I can't find from which revision comes this patch between -19 and -21.

Does someone knows why this patch was integrated in -21 ?
Was the code in -19 buggy ? If not, it should be quite usefull to roll back to the code of -19 for hub.c.

This bug is quite annoying for my users who can't use their intern usb-hub anymore. (which means that they have to boot under -19 to work).
