I have a laptop (HP 6910p) which is plugged into a docking station which is connected to a KVM (IOGEAR GCS1764) and when my mouse (Logitech MX1100) is connected to the KVM console port it fails to work correctly with the laptop, however, if the mouse is plugged directly into the laptop it works as expected. I have been able to verify that the mouse does work correctly through the KVM as I have a second system (Dell Precision 530) connected to the KVM and the mouse works correctly on that system. I've tried running several different kernels on the laptop, including gentoo-sources-{2.6.27-r8,2.6.27-r10,2.6.28-r4}, and the same behavior is shown on each release. I will attach my kernel configuration and dmesg output (mouse is identified as "idVendor=046d, idProduct=c526") from 2.6.28-gentoo-r4 to this bug. I've tried to run "lsusb" when the mouse is attached but it hangs and never returns, "lsusb" runs normally when the mouse is not attached. Let me know if you need any additional information, I'm more than happy help try and resolve this issue. Reproducible: Always Steps to Reproduce: 1. Boot system 2. Plug in mouse Actual Results: See attached dmesg output. Expected Results: Working mouse.

Can you test with gentoo-sources-2.6.29.
Same problem with gentoo-sources-2.6.29, I've updated the kernel config and dmesg output.

Created attachment 186671 [details] Dmesg output for gentoo-sources-2.6.29
I don't know anything about this hardware but I saw something about connecting the receiver to the KVM mouse port. Does that make sense and is something that can be tried?
That is the problem, if I connect the mouse/receiver to the KVM's mouse port it fails; if I connect the mouse/receiver directly to the laptop it works. Right now the workaround is that I have to keep moving the mouse/receiver manually between systems instead of letting the KVM do it for me. Needless to say this is getting very annoying and I'd like to resolve this issue. Is there any more information I can provide to help? I'm very anxious to solve this problem.
Do you have another mouse to test with?
I do not currently have another working USB mouse (this new mouse replaced my previous mouse which died) but when I did everything worked fine. Also, I've determined that this problem does not appear to be hardware related as I can boot the laptop into windows with the mouse plugged into the KVM and everything works as expected. The problem appears to be caused by the combination of Linux and the mouse plugged into the KVM.
Can you attach lsusb -v with mouse attached directly.
Created attachment 188603 [details] Lsusb output for gentoo-sources-2.6.29-r1
Thanks for looking into this problem, hopefully the lsusb output will help.
Can you build a kernel with CONFIG_USB_DEBUG enabled, then boot the system without the mouse plugged in anywhere. *After* it has booted, plug in the usb mouse, run "dmesg" and attach the output here. Then run "lsusb -v", it will hang? Run dmesg again, look for any *new* messages at the end of the output again and note them here. Thanks!

I've attached dmesg output for the system after it boots (1) but before plugging in the mouse, after plugging in the mouse (2) and finally after running "lsusb-v" (3). As noted previously, lsusb just hangs with no output so I wasn't able to capture anything useful from lsusb. If you need me to run any special patches to help instrument the USB code just let me know. Looking at the dmesg output, there was no change between the output in (2) and (3) but running diff between (1) and (2) yields the following at the bottom of the output: @@ -686,3 +641,45 @@ kjournald starting.

It has been a while since I've seen any updates, any progress on this bug that you can share? I just booted 2.6.30-gentoo-r1 (see recent attachments) and the situation is marginally improved but the mouse still does not work. If there is anything I can do to help please let me know, this is growing increasingly frustrating. Thanks.
have you tried with gentoo-sources-2.6.30-r4?
(In reply to comment #24) > have you tried with gentoo-sources-2.6.30-r4? No, not yet. Is there any indication that this will fix the problem or are we just grasping at straws hoping a new kernel revision will magically solve things? I've supplied several logs w/o any real feedback about what may be going on - does anyone have any hunches yet? Do you need me to capture something else to help?
Same problems with gentoo-sources-2.6.30-r5
Hey Paul, sorry for keeping you waiting all this time. I take it you have enabled the "NoDCC" option on your Xorg, right? If you have the courage, I'd encourage you to submit this bug upstream. It will probably get things moving :) Thanks for the bug report!
Once you submit upstream, please attach the link to the bug in this report.
Where should I report this upstream? Pointers are appreciated ...
(In reply to comment #29) > Where should I report this upstream? Pointers are appreciated ... > You should file the bug in bugzilla.kernel.org under the Drivers -> Input Devices section. Just to double check, did you try the "NoDCC" option on your Xorg?
