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

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. $ grep -H 'usb' *lsmod*sorted*ern*.txt ad2kz1gKern2627-11lsmodOutput__20090505sortedOlderKernel.txt:libusual 30356 1 usb_storage ad2kz1gKern2627-11lsmodOutput__20090505sortedOlderKernel.txt:scsi_mod 155212 7 st,sbp2,sg,sr_mod,sd_mod,usb_storage,libata ad2kz1gKern2627-11lsmodOutput__20090505sortedOlderKernel.txt:usbcore 149488 7 usblp,usb_storage,libusual,ehci_hcd,ohci_hcd ad2kz1gKern2627-11lsmodOutput__20090505sortedOlderKernel.txt:usblp 20480 1 ad2kz1gKern2627-11lsmodOutput__20090505sortedOlderKernel.txt:usb_storage 82624 2 ad2kz1gKern2628-11lsmodOutput__20090505sortedNewerKernel.txt:usblp 20224 1 -- kernel 2.6.28 from 2.6.27 prevents Alcor reader working https://bugs.launchpad.net/bugs/372232 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
