Comment 5 for bug 372232

Comparing the output of lsmod when running Kern2.6.27-11 versus Kern2.6.28-11 shows that
the module usb_storage is not being loaded when the system runs the newer Kernel 2.6.28-11

What I cannot answer at this time is why usb_storage is not being loaded when running the newer kernel.

When running Kern2.6.27-11 there is mention of a module named libusual which some reading (link below) suggested might have now been removed from Ubuntu Kernels of Jaunty and forthcoming Karmic.
   http://www.linux-archive.org/ubuntu-kernel-team/287813-sru-disable-libusual-ub.html
but I am still puzzled as the narrative seemed to suggest to me that not having libusual would just mean usb_storage itself picks everything up directly. My expectation would then be that lsmod when running the newer Kernel should
include usb_storage and related modules (but exclude libusual).

This is not the so in my case.
