Following is what I needed to do to get FC1 to recognize my USB external hard drive. I. Make certain that all of the required OS modules are available. Installation of the source modules for the version of the kernel currently in use is required. A. Open a terminal window. B. Enter "su -" C. Enter root password. D. Modify the module configuration 1. Enter "cd /usr/src/linux;make xconfig" 2. Make certain that the needed options are set to "Y". a. Under "USB support", I needed the following: 1. USB support 2. Preliminary USB device filesystem 3. UHCI support Some machines may require OHCI support instead 4. USB Mass Storage support Examine this list for the devices you may have b. Under "SCSI support" and "File systems" additional items needed to be checked for my configuration. 3. Save & Exit E. At the command line, enter "make dep". II. Add the following line to /etc/modules.conf alias usb-controller usb-uhci III. Reboot the computer. Additional comment: I believe the the necessity for a procedure like this is hindering full acceptance of Linux. I had my USB hard drive operational under RH9, but FC1 did not detect my settings, bringing them forward to the new installation. I filed a bugzilla request with Red Hat so that Anaconda (the installer) would detect and maintain prior settings, but my request was closed under "WONTFIX". When one is upgrading from one version of an OS to another, it might be well to use "make xconfig" on the old system to save the settings to a file (that might be on a floppy). After installing the new version, "make xconfig" might be used to load the settings. I lack the skill to do so, but I'd like to see a program written that would be able to detect what one has attached to his computer and to automate the above procedure. The big problem, from my perspective, is to learn what modules must be used for any given device and what lines must be entered in modules.conf for any given device. If it is not possible for a program to detect what is attached to a computer before the modules are installed, another option would be to list devices and ask the user to select those that he has. Are there any system programmers willing to tackle a project like this? Alan P.S. This is not just a Fedora problem. It applies to earlier OS versions also.
