It's possible. Most of those changes are innocuous. They add routines that don't get used until a later patch. However one of them might be responsible. On Fri, 8 Sep 2006, Rafael J.

This patch affects OHCI. You can try reverting it, to see if that makes any difference. It probably should have been left out of -mm, since it interacts pretty strongly with some later USB PM patches that did get left out. gregkh-usb-usbcore-remove-usb_suspend_root_hub.patch > Here's the relevant part of the dmesg output: > > usb usb1: resuming > usbdev1.1_ep00: PM: resume from 0, parent usb1 still 1 > hub 1-0:1.0: PM: resume from 0, parent usb1 still 1 > hub 1-0:1.0: resuming > usbdev1.1: PM: resume from 0, parent usb1 still 1 If reverting that patch doesn't help, please post the relevant dmesg log after setting CONFIG_USB_DEBUG.
