From Bugzilla Helper: User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040113 Description of problem: My machine has a Intel 8280 1DB/DBM USB controller built into the motherboard. After installing Fedora Core 2 test3 (stock) when it reboots it tries to initialize USB and fails. This prevents my keyboard and mouse from working. I am able to ssh into the machine to try things, and I'm willing to try and work through it. The USB support works fine during the install, so I'm guessing this is a USB 2.0 bug. I assume the installer only knows about USB 1.0. Is there a way to disable uhci_hcd from trying to do USB 2? What kernel does the installer use? Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Install Fedora Core2 test3 2.Reboot Actual Results: As soon as it gets to the point of loading uhci_hcd it finds my controller and then fails with "host controller halted, very bad!" The machine continues to boot, but I have no USB for keyboard or mouse.

My machine is a Dual Processor Xeon 2.4 GHz machine with HT enabled. I have 3GB of RAM, and an 80GB hard drive. I don't know the MOBO offhand, but I can look it up with a reboot.
Did you try to comment uhci_hcd from /etc/modprobe.conf and add ehci-hcd ?
It was already loading ehci_hcd, and when I disabled uhci_hcd the keyboard and mouse still didn't work. The lights stayed on, so the USB controller wasn't disabled, but there was no input. My guess is my USB controller needs uhci_hcd (not ehci_hcd), but there is something incorrect with the driver.
More likely, driver is fighting with the BIOS.
Well, I do have "Legacy USB" turned on in the BIOS, but that is the only way that Grub will work. I suppose as an ugly workaround I could have Fedora Core 2 be the default target, and if I want to boot something else, I just switch my bios setting. Just to test it, I will do a reboot, but that's certainly not the situation I would like to stick with.
Well, I did the test, but without luck. Nothing I did allowed uhci_hcd to load properly (and as I mentioned ehci_hcd doesn't support my USB devices.) Does anyone know the flags for uhci_hcd so that I can disable USB2 if I have to?
I was looking through some of the kernel logs, and I saw that in the Changelog for 2.6.6 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.6 And I saw that there were fixes for UHCI. Probably this is the important one: [PATCH] USB: Important bugfix for UHCI list management code Anyway, I installed 2.6.6-bk8, and now UHCI loads fine and I have USB support again.
So, does 2.6.7-1.494.2.2 work? If yes, please close.
I updated to the latest kernel available from Up2date (I think it was still a 2.6.5 kernel). And with that kernel, it had a kernel panic, rather than booting and not allowing USB to run. I didn't see a way to install 2.6.7-1.494.2.2, is it not Up2date, or did I just miss something. John
mass update for old bugs: Is this still a problem with the 2.6.9 based update kernel ?
I went ahead and upgraded to FC3, and the problem seems to be fixed. On FC2, I tried a couple of the up2date kernels, and none of them worked. (Though they generally failed with a kernel panic, rather than running with USB disabled.) John =:->
OK, I'm closing this. P.S. If self-built kernels do not run, usually it's because something was wrong with initrd: operator forgot to run mkinitrd, or other failure. I use lots and lots of self-built kernels on FC2 & FC3.
