Description Glenn Sommer 2007-02-03 08:25:41 UTC
I'm running the gentoo-2.6.18-r6 kernel.
I have one USB logitech trackball mouse, and one USB MX518 logitech mouse.
When booting I can see in dmesg that the kernel does only detect my first mouse (even though both mouses are attached to an USB port).
But if I then remove the second mouse, and plug it in again - then the kernel sees the new hardware - and I'm able to use both mices.

Reproducible: Always

Steps to Reproduce:
1. attach two mices to the computer (using USB)
2. boot gentoo
3. login as a normal user
4. execute 'dmesg' and look for the mouse.
(Here you'll only see one of the mice attached)
5. remove the other mouse from the USB port, and plug it in again.
6. execute 'dmesg' again, and now the kernel has detected the second mouse.

Actual Results:  
After using the steps above - both mices work at the same time.

Expected Results:  
I would expect the kernel to detect both mices at boot time.

When re-attaching the mouse one is able to catch the input of moth mice at /dev/input/mice
If one would like to catch the input of the first mouse, that would be /dev/input/mouse0, and the second mouse would be /dev/input/mouse1

Please, try w/ 2.6.19-r5. Also relevant dmesg output would be useful I guess.

The bug is still there with 2.6.19-r5.

closing as needinfo since that site will not load for me

I've tried with kernel 2.6.20 - and now the problem is gone.
So this should be marked as closed.
