Bug 190106 – problem with USB trackball within 2.6.22-r5-gentoo-sources

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description phrexianreaper 2007-08-24 22:21:04 UTC]

With the 2.6.22 gentoo-sources kernel, there seems to be a problem with USB trackballs. When I upgraded the first time (to -r2), I lost the use of my trackball (which is running via USB and event interface), and went back to 2.6.21 until the next .22 release. With -r5, the problem still persist, but while with -r2 I had only 2 event interfaces, I now have 4.

I've run lsusb a few times, tried diffrent USB ports in my system, and while my normal mouse (pluged into my PS/2 plug so my keyboard will act as expected) works, my trackball doesn't. I've tried catting out the event? interfaces, and the by-path interfaces as well.

Reproducible: Always

Steps to Reproduce:
1.Upgrade to 2.6.22-r?
2.Try to use a USB-based trackball
3.Watch nothing happen

Actual Results:  
Wasn't recognized

Expected Results:  
Have given me a useable trackball like in 2.6.21

Logitech trackball.

This has nothing to do with any Gentoo release.

[Comment 2 Mike Pagano 2007-08-24 23:39:55 UTC]

Can you please attach the following:

.config for last working kernel
.config for .22-r5
dmesg
lspci -v
lsusb -v
cat /proc/bus/input/devices

Also, can you please test with the latest vanilla kernel which is version 2.6.23_rc3 as of this writing.

This is likely to be fixed upstream; from the 2.6.22.6 changelog:

    usb: add PRODUCT, TYPE to usb-interface events
    
    This fixes a regression for userspace programs that were relying on these events.

Thanks for pointing that out Jouni. gentoo-sources-2.6.22-r6 includes this, hopefully it fixes the problem.

[Comment 6 phrexianreaper 2007-09-02 02:07:04 UTC]

Sorry for the lack of response to this bug. I'm going to try -r6 and see if it helps. If not, when I get some more free time, I'll start into the rest.

[Comment 7 phrexianreaper 2007-09-02 20:43:20 UTC]

I've upgraded the kernel to -r6, and it seems to work. Might as well resolve this bug.

[Comment 8 Maarten Bressers (RETIRED) 2007-09-02 22:47:19 UTC]

Since switching to gentoo-sources-2.6.22-r6 fixed the issue for you, I'm closing this bug.
