Description oliver 2004-07-27 09:29:38 EDT
Description of problem:

USB does not initialize properly, no USB device is usable.

Version-Release number of selected component (if applicable):

Tested with 2.6.6-1.435 (Fedora Core 2 updates) and 2.6.7-1.478
(Fedora Core 3 test 1, on an otherwise fully up-to-date Fedora Core 2

How reproducible: Always

Steps to Reproduce: N/A
Actual results: 

USB does not work at all.  With the 2.6.6-1.435 kernel,
cat /proc/bus/usb/devices shows only the hub, any other device is not
registered (plugging devices in and out does not create syslog messages).

With 2.6.7-1.478, cat /proc/bus/usb/devices simply hangs.

Expected results: 
At least USB devices should register on the bus.  Devices have worked
on an older Redhat 8 system on the same machine.

Additional info:

Will attach /var/log/messages

I should add that it's a Gigabyte GA-7IXE4 mainboard (AMD Irongate

After some digging I found an old report in bugzilla which I filed
when some early 2.4 kernels broke USB on the same mainboard:

Still no USB with Fedora Core Test 3 (2.6.8-1.541 kernel).
Comment 4 oliver 2005-03-01 14:11:58 EST
Problem solved with 2.6.10 kernels.
Comment 5 Dave Jones 2005-07-15 15:55:36 EDT
An update has been released for Fedora Core 3 (kernel-2.6.12-1.1372_FC3) which
may contain a fix for your problem.   Please update to this new kernel, and
report whether or not it fixes your problem.

If you have updated to Fedora Core 4 since this bug was opened, and the problem
still occurs with the latest updates for that release, please change the version
field of this bug to 'fc4'.

Thank you.

As I was writing in comment #4, the problem has disappeared since kernel
2.6.10.  I have since upgraded to FC4, and everything is still working fine.
I think the bug can be closed.
