Description Aaron VanDevender 2003-11-19 04:47:59 UTC
Description of problem:
I have a Microsoft Natural Pro keyboard and it randomly freezes up
when I'm typing. It will continue to print whatever letter I was
hitting when it froze, and typically all of the lights (num, caps,
scroll) come on. It usually regains its senses when I unplug it, plug
it back in and type something. Sometimes when it freezes the lights go
on and rather that simply repeating a character it shuts off certain
keys like alt. It is quite annoying. It may or may not be related to
Bug 64068, and it almost certainly is related to this:


which tracks the bug in the 2.6-test series of kernels. I'm suspecting
some part of the USB system was backported from the 2.6-test series
into the 2.4.22 kernel that Fedora Runs.

The most bizzare thing was that this system was a RH9 system, which I
upgraded to FC1, and never saw the bug. Then, for various reasons, I
did a clean install of FC1 and the bug showed up. I swapped for an
identical keyboard and the bug persists. I did another clean install
of FC1 and I still have the bug.

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

Comment 1 Pete Zaitcev 2003-11-19 18:06:27 UTC
Can the problem be reproduced this in text mode (Ctrl-Alt-F1)?

Comment 2 Aaron VanDevender 2003-12-03 23:04:56 UTC
Yes, problem can be reproduced in text mode. It gets reset by
unplugging and plugging back in the keyboard, as it does in X. Problem
persists in kernel 2.4.22-1.2129.nptl.athlon.

Comment 3 Pete Zaitcev 2003-12-03 23:16:18 UTC
Thanks heavens, text mode says we're in business.
Please do this: get it to die, replug, if it resets ok and
the box survives, run "dmesg > /tmp/dmesg.out" and attach
dmesg.out to the bug (but do not drop into comments box).

Ok, I attached the output of dmesg.

verbose usb kernel messages during freeze/replug

I recomplied the kernel to enable more verbose USB debugging output, then I
waited for the keyboard to freeze, and after replugging it, I saved the kernel
messages. Said messages have been attached.

Comment 6 Aaron VanDevender 2004-06-15 17:42:15 UTC
Problem still exists with FC2 (kernel-2.6.5-1.358). I have
demonstrated it now using two keyboards, and 2 motherboards. They
keyboards are identical (Microsoft Natuarl Pro) but the mother boards
are different. One is an Asus A7V600, and the other is an MSI
KT6V-LSR. They are both based on the VIA KT600 chipset, and probably
have the same USB controller. Both keyboards operate normally when
plugged into a machine based on the KT400 chipset.

Comment 8 Aaron VanDevender 2004-06-17 23:57:32 UTC
I built the newest kernel (2.6.6-1.435) using CONFIG_USB_DEBUG and added:

#define DEBUG
#define DEBUG_DATA

to hid-core.c, hid-input.c, and usbkbd.c. It seems like every thing
rolls along fine until the all the keyboard lights turn on and the
keys go funny, and I get these kernel messages, until I replug:

Jun 17 17:59:09 lazlo kernel: usb 2-1.1: control timeout on ep0in
Jun 17 17:59:14 lazlo kernel: usb 2-1.1: control timeout on ep0in

I've attached the whole kernel log in Comment #7.

Comment 9 David Lawrence 2004-09-29 19:41:48 UTC
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

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/

Comment 10 Aaron VanDevender 2004-09-30 01:29:05 UTC
Even though this bug was marked FC1, it still exists in the latest FC2
kernels, and therefore doesn't deserve being closed with a WONTFIX and
swept off to fedora legacy. However, if you insist, I can always open
another bug that targets FC2 (and possibly FC3-test as well).

Comment 11 Pete Zaitcev 2004-09-30 02:29:23 UTC
Well, it's not as if David's script can read minds and know if
a bug against FC1 can be applicable to FC2... :-)

Aaron, I see you retargeted the bug already, so just reopen it then.

Comment 12 Aaron VanDevender 2004-10-24 15:44:48 UTC
Evidently this behavior is caused by having gpilotd running. It can't
handle the poling of the USB that gpilotd does. There is some
concensus that this is a hardware flaw rather than a software bug.
Eitherway, its a dup.
