ecm200 0 Posted September 19, 2004 Hi, I am having problems with the usb system on Fedora Core 2. I have all the latest updates. I am running Kernel 2.6.8. kernel-2.6.8-1.521.i686.rpm kernel-utils-2.4-9.1.131.i386.rpm usbutils-0.11-4.i386.rpm I found on other threads that changing the standard alias lines in modprobe.conf which was set to this as default: alias usb-controller ehci-hcd alias usb-controller uhci-hcd Looking at the posts, I then changed this to: alias usb-controller uhci-hcd alias usb-controller1 ohci-hcd I also entered the following line into the rc.local file: modprobe ohci-hcd uhci-hcd My system is about 2 years old and is an Evesham chasis. It has the following: 120GB first drive 80GB slave drive (linux installed on this drive) nVidia GeForce 4 Ti2600 128MB RAM 6 USB 2.0 Ports 1 USB 1.0 4 Port Hub HP DJ950C attached to usb Logitech QuickCam Pro attached to USB Microsoft Intellipoint Optical Mouse to USB Keyboard to PS2 port Microsoft Bluetooth Dongle to USB Alcatel Speedtouch USB ADSL modem. 512 MB RAM SoundBlaster Audigy soundcard. PROBLEM: After setting the files as shown above and rebooting this works correctly and sets up the usb ports correctly. KUDZU on boot up detects the quickcam and the printer and configures them. Subsequent reboots within an hour have no affect and system works fine. After leaving the computer for an extended period of time or after having worked in Windows XP for a period of time and rebooting into Linux, usb initialisation does not occur. On this boot up, KUDZU will detect the absence of the printer and the camera and ask to remove the configuration. After completing boot up and changing the modprobe.conf and the rc.local back to default and rebooting. On reboot the mouse does not work and KUDZU does not detect anything else. If the files are then changed back again to above and the system is rebooted then in most cases the usb is initialised correctly and all USB devices work correctly including the mouse. In one case, the mouse also worked with the default setup as well. Please could you advise me on what the problem maybe and how to solve it. I have read that maybe I need ehci and ohci support but not uhci support. Regards Ed Morris edward@morris.vispa.com Share this post Link to post
