Dump of usbmon while mouse is working
A patch that fixed it for a couple users
Description Christoffer S 2005-10-20 14:30:56 UTC
Most recent kernel where this bug did not occur: 2.6.10 Distribution: Ubuntu Hardware Environment: AMD Athlpn 1300, Nvidia GeForce2, Logitech Optical USB Mouse Software Environment: Ubuntu 5.04/Ubuntu 5.10 Problem Description: Booting into Gnome and reading webpages. Not using the mouse for a while. When I grab the mouse and want to move the pointer, the mouse is frozen. I have to switch terminals (Ctrl+Alt+F1) and back to F7 to get the mouse working again. Steps to reproduce: 1. Boot, log into Gnome. 2. Use your computer for a while (eg. type in a bugreport on kernel.org) 3. Move the mouse pointer. It appears frozen. This did not appear in kernel 2.6.10. The problem is apparent also in 2.6.12.
Comment 1 Dmitry Torokhov 2005-10-20 14:53:33 UTC
Does the mouse freeze if you are using it with GPM in console? What device are you usign to get mouse data (/dev/input/mice, /dev/psaux, etc)?
Comment 2 Christoffer S 2005-10-21 00:48:32 UTC
I am using /dev/input/mice. Using gpm it freezes also. When I started using gpm and when the mouse froze, I could not get to unfreeze again by switching terminals. I have tried looking in syslog, messages and dmesg, nothing there to pinpoint the problem.
Comment 3 Greg Kroah-Hartman 2005-11-14 21:41:08 UTC
Does this happen on 2.6.14?
Comment 4 Christoffer S 2005-11-17 11:45:31 UTC
I just tried kernel 188.8.131.52 and the same thing happened. Is there any debug logging I can set or see somewhere?
Comment 5 Christoffer S 2005-12-05 11:16:21 UTC
I am using kernel 2.6.15 on Ubuntu development version and the same thing happens. There is no information in kern.log or messages.log. My mouse is a Logitech Optical Mouse M/N: M-BD58. I've tried using a PS/2 adaptor and the mouse works fine.
Comment 6 Alan Stern 2006-02-03 19:53:14 UTC
There are two things you can do. First, turn on CONFIG_USB_DEBUG and check the dmesg log. Second, use the usbmon facility to keep track of USB data flowing back and forth (see the instructions in Documentation/usb/usbmon.txt). This should tell us if the problem is in the lower part of the driver stack.
Comment 7 Greg Kroah-Hartman 2006-03-06 10:27:56 UTC
No response in 2 months, closing. If this is still a problem, please reopen with the requested information.
Comment 8 Christoffer S 2006-03-18 01:42:32 UTC
Hi, Sorry for my late answer. I have tried using usbmon on 2.6.15 but I did not see all my usb devices, only 2 ( I have three usb devices, a mouse, keyboard and a logitech headset). I followed the instructions in usbmon.txt, mounted the debug_fs. In the doc it says: ls /sys/kernel/debug/usbmon 1s 1t 2s 2t 3s 3t 4s 4t but I only have 4: 1s 1t 2s 2t Also it says, cat /proc/bus/usb/devices but dir /proc/bus/usb/ gives an empty directory. From lsusb: Bus 001 Device 004: ID 046d:c00c Logitech, Inc. Optical Wheel Mouse So it must be device 4 but that does not correspond to ls /sys/kernel/debug/usbmon. I am pretty confused.
Comment 9 Alan Stern 2006-03-18 10:23:38 UTC
The entries in /sys/kernel/debug/usbmon correspond to your computer's USB controllers (or buses), not to USB devices. Apparently your computer has only two controllers, so there are only four files. Since the mouse shows up on bus 1 according to lsusb, the file you need to monitor is 1t. In some distributions, /proc/bus/usb isn't mounted by default. You have to mount it by hand: mount -t usbfs none /proc/bus/usb

Created attachment 7602 [details] dump of usbmon This is a dump of usbmon. The mouse freezed while catting 1t. I stopped, unplugged the mouse and then plugged it in again.

Created attachment 7603 [details] Dump of usbmon while mouse is working This is a dump after the mouse was unplugged and plugged in again (ie. while the mouse was working).
Comment 12 Alan Stern 2006-03-22 07:33:04 UTC
The dump indicates that the mouse simply stopped working. Of course, it's possible that the USB host controller stopped working instead. Have you tried booting a 2.6.10 kernel recently? Do you know that it still works? What shows up in the usbmon output if the mouse freezes under Gnome and you unfreeze it by switching terminals?
Comment 13 Christoffer S 2006-03-22 08:54:56 UTC
Hi, I'm using 2.6.10 (Ubuntu Hoary - 5.04) on a daily basis and there are no problems here. I have see other people reporting this problem: https://launchpad.net/distros/ubuntu/+source/linux-source-2.6.15/+bug/20125 http://www.ubuntuforums.org/showthread.php?t=127027 There is a difference using 2.6.12 and 2.6.15. On 2.6.12 I can unfreeze the mouse by switching terminals. On 2.6.15 I have to unplug it. Switching terminals does not work.
Comment 14 Alan Stern 2006-03-22 09:19:55 UTC
Okay, try doing this with 2.6.15: Turn on CONFIG_USB_DEBUG in the kernel configuration and make sure that CONFIG_USB_HID is set to M, not Y. Rebuild the USB drivers and load uhci-hcd with modprobe uhci-hcd debug=3 Next, mount /sys/kernel/debug. When the mouse freezes, go to /sys/kernel/debug/uhci and post the contents of the file which corresponds to the USB controller the mouse is plugged into. After that, try doing rmmod usbhid modprobe usbhid and see if that gets the mouse to start working again.

Created attachment 7698 [details] A patch that fixed it for a couple users Try this patch - it fixed it for a number of SuSE users. I believe I have sent it to Dmitry already, if not, please correct me. The problem is that the mouse in question sometimes caused EILSEQ intermittently, resulting in the driver giving up on it. This makes the driver ignore the intermittent errors.
Comment 16 Christoffer S 2006-03-30 09:08:16 UTC
The provided patch works for me. Thanks to everyone.
Comment 17 Dmitry Torokhov 2006-03-31 09:34:18 UTC
Alan has reworked HID driver interrupt handling quite a bit, could you please try the latest git snapshot (or 2.6.17-rc1 when it comes out)?
Comment 18 Christoffer S 2006-03-31 09:38:58 UTC
I'll try 2.6.17-rc1 when it comes out.
Comment 19 Christoffer S 2006-04-06 11:21:50 UTC
2.6.17-rc1 seems to be working fine. The mouse doesn't freeze.
