From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3) Gecko/20030314 Description of problem: After installing RedHat 9 on my system, my USB interface doesn't work when the USB 2.0 controller is disabled (and only the standard interface is enabled). The symptoms: I had a system with RedHat 8.0 (and Windows XP) installed. I have a Gigabyte GA-7VAXP motherboard (with a VIA KT400 chipset), which has USB 2.0 support. I had the USB 2.0 support turned on in the BIOS, but never used any such devices (only old USB devices). I installed RedHat 9 (clean install, not an upgrade), and now the only way any USB devices work if I have the USB 2.0 option enabled in the BIOS and use the RedHat kernel from RPM. No USB devices are recognized if I either - turn off USB 2.0 support in the BIOS - compile kernel 2.4.20 with the configuration I used for my RedHat 8.0 install (and which worked fine before) - boot Windows XP (apperantly it doesn't have USB 2.0 support) previously, under all these circumstanses all USB devices worked fine. did the RedHat 9 install do something that made the USB interface work only in 2.0 mode, period? Version-Release number of selected component (if applicable): kernel-2.4.20-9 How reproducible: Always Steps to Reproduce: 1. install RedHat 9.0 on a GA-7VAXP motherboard 2. try to use USB devices with USB 2.0 support turned off in the BIOS 3. Actual Results: no USB devices are recognized under the following cicrumstances: - turn off USB 2.0 support in the BIOS - compile kernel 2.4.20 with the configuration I used for my RedHat 8.0 install (and which worked fine before) - boot Windows XP (apperantly it doesn't have USB 2.0 support) Expected Results: USB devices should be recognized Additional info: this is extremely annoying. I can't use my Other Operating System and I can't use my own kernel, because USB devices (like my mouse) won't work. Also, it is very disturbing if the install really changed my motherboard in a permanent way (so as to only work in USB 2.0 mode)
Please check if /etc/modules.conf has ehci-hcd alias, and comment it. It's not a kernel option. Anaconda sees a USB 2 interface and since it has no way to know if it's useable (or even connected to back panel), it enables it optimistically. Before RHL9 there was no USB 2 HC (EHCI).
Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/
