This is caused by enabling CONFIG_USB_LIBUSUAL=y. Despite being documented as a "module" when it was added (complete with the suggestion of setting options in modprobe.conf), this is a boolean option. So it's built into the kernel, which means it doesn't get another bash at coldplug after the root filesystem is mounted.
Please, can you disable CONFIG_USB_LIBUSUAL? The reason for it is CONFIG_BLK_DEV_UB - "Low Performance USB Block driver. If you enable this driver, it is recommended to avoid conflicts with usb-storage by enabling USB_LIBUSUAL. If unsure, say N." I can't imagine why Ubuntu needs this. AFAIK the only reason for it is to save a few K on embedded systems. It might be interesting for debugging purposes, but as this (and other previous bugs) have shown, it seems generally more effective at inserting bugs into a systems that should be working. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1062796 Title: usb-storage devices don't work, unless plugged in *after* booting - happens when setting MODULES=dep in initramfs.conf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1062796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
