I have same problem for 3 years and still on Kununtu 9.10 But I have solution. On page https://bugzilla.kernel.org/show_bug.cgi?id=5410 is reason and simple patch. I created new patch which add new param power_off_usb in ohci-hcd module.
With this patch my computer finally turn off all usb devices after halt. Finally my USB mouse doesnt light when computer is turned off. I have recompiled kernel (package linux-image-2.6.35-7-generic) with this usb patch in my PPA https://launchpad.net/~pali/+archive/pali Because module ohci-hcd is static linked to kernel, param power_off_usb is needed to add in grub. Add this line in /boot/grub/grub.cfg and then run: sudo update-grub GRUB_CMDLINE_LINUX="ohci_hcd.power_off_usb=1" ** Bug watch added: Linux Kernel Bug Tracker #5410 http://bugzilla.kernel.org/show_bug.cgi?id=5410 -- USB devices are not powered off at shutdown https://bugs.launchpad.net/bugs/42149 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
