Much of this is well documented in a duplicate of this bug, #106410 (I hadn't found this bug listing when I filed it):
https://bugs.launchpad.net/ubuntu/+source/linux- source-2.6.20/+bug/106410 In addition to output from lspci and lshal, it has before/after suspend/resume logs of dmesg, lsmod, and lsusb. Should be useful for debugging. Perhaps the most interesting point is that after resume, the hub itself doesn't seem to be dead (according to lsusb), yet the devices that are plugged into it just don't get re-registered. Adjusting /etc/default/acpi-support to unload/load usb modules for the suspend/resume does get rid of the dmesg lines saying "usb usb1: root hub lost power or was reset," but the behavior doesn't change, nor does what lsusb reports. See that bug report for details. -- USB does not have power after wake-up https://bugs.launchpad.net/bugs/99267 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
