Description of problem:
Filed under 'kernel' only because that's my first guess as to where the problem
I think my bug may be the same as this one:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=85933 But I'm not sure an
Pete Zaitcev asked others to file their own bugs.
Anyway, under Red Hat 8 and some of the betas of 9, my USB mouse and keyboard
were working fine. I could see the usb hubs, and the usb devices I connected
(mouse, keyboard, camera, etc.) could be seen fine as well.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Boot system
2. Look for USB devices anywhere
Actual Results: Couldn't find any USB devices. Or any error messages in
/var/log/messages of note.
Expected Results: USB devices and hubs should be listed and able to be used...
I have a Gigabyte GA-7VAXP motherboard, which uses the VIA KT400 and USB 2.0.
Red Hat selects and uses the ehci-hcd kernel driver for the VIA USB 2.0 Controller.
No USB devices appear in /proc/bus/usb except for 001/001, which is the USB
controller itself. There are no hubs, no mice, no keyboards. Just the controller.
'lsusb' gives me a lot of "Unknown line at line xxx" error messages. (First line
58, then lines 2296 through 2335). It then listes the information for device
001/001, my controller.
One suspicious thing of note is the following two lines from /var/log/messages
PCI: 00:10.3 PCI cache line size set incorrectly (32 bytes) by BIOS/FW.
PCI: 00:10.3 PCI cache line size corrected to 64.
PCI device 00:10.3 is my USB controller.
I've tried compiling an official Linus kernel 2.4.20. Still no usb hubs/devices.
I also tried installing the Red Hat 8 2.4.18-27.8.0 kernel. Still no usb
I'm pretty certain that this stuff worked fine under Red Hat 8. It works fine
under Windows XP.

This seems to have been some sort of problem in upgrading from Red Hat 8 (or one
of the 9 betas) to Red Hat 9. My problem was solved by removing all USB entries
from /etc/sysconfig/hwconf, restarting, letting kudzu add and configure the USB
stuff again and then restarting. I did that a few times and the USB devices all
of a sudden appeared and worked again.
So, can I close this now?
Bill Nottingham says that the upgrade problem was fixed in Anaconda.
Well, if the upgrade problem was solved, sure. :)
OK, now closing the right one. Poor scowles :-)
