synaptics touchpad not recognized when usb mouse plugged in

RaraRasputin

hi,
i have a problem with my touchpad. i just installed gentoo on an ibm thinkpad r40 and compiled kernel 2.6.5 from the gentoo-dev-sources.
my usb-mouse worked without any problems, but the touchpad is only recognized, when the external mouse is not plugged in when booting. when i boot without the external mouse, it is detected and even if i plug in the external mouse after booting both devices work.
i have the evdev, psmouse, ohci-hid, ehci-hid, uhci-hid and hid compiled into the kernel.
when i tried to compile these drivers as a module, loading the module psmouse at boot time cancelled just saying "Quit" and the boot process stopped and i was asked for the root password for rescue or such.
after giving the password i tried to modprobe the modules manually, which worked without errors, but psmouse kept saying "quit" both on modprobing and rmmod, and neither the touchpad nor the external mouse was detected.

thanks in advance,
Rasputin

I have the exact same problem: the (2.6.7-gentoo-r1) kernel only detects the synaptics touchpad fine when my external usb mouse is not plugged in. I can plug it in after booting without problems.

Anyone found a solution yet?

do you use xfree86? if you do you may want to create another mouse device in the configuration file. i use both a usb mouse and synaptics at the same time without problem in X.

The problem is not X related (I'm using X.org btw). The kernel doesn't recognize the touchpad when booting with the usb mouse attached, and it does fine when I unplug the mouse. Once booted, I can reinsert the mouse, and X works fine with both the touchpad and the usb mouse.

Please try loading all USB modules (including hid) before loading psmouse module - you most likely experiencing troubles with USB legacy emulation.

No, I do not. You want to load USB modules so uhci-hcd will turn the legacy emulation off (see uhci_reset()).

USB legacy emulation is a thing that makes older simple OSes (read DOS) see USB mouse as a PS/2 mouse and use it without USB drivers loaded. USB legacy emulation is done by BIOS and usually interferes with advanced modes of devices like Synaptics touchpad.

So what happens if you load USB modules before psmouse (evdev does not touch harware at allso it is irrelevant here)? Or if you don't load USB modules at all? Is your touchpad broken in these cases?

(OHCI does the same thing as UHCI - look for "USB HC TakeOver from BIOS/SMM" message)

Is there any way to tell the kernel which driver to load first, when compiled in? I guess not, so I'll just compile all my usb and psmouse drivers as modules.

Try the following parameter for grub:

janiskr · n00b Joined: 09 May 2004 Posts: 56 Location: Riga, Latvia

For touchpad to work in kernel compile in ps/2 support (psaux) or whatever it is called
then turn on hotplug

then configure your XF86Config-4 or xorg.conf

than core pointer uses

Device "/dev/input/mice"

i'm using Protocol IMPS/2 and anyting is working (except extended touchpad features like dblclick and scrolling

and configure it as if it where simple mouse or whatever you have, save, and restart X

if something is NOT working check your dmesg, check usbwiev if it show your mouse attached if anyting is OK you can even plug usb mouse when X is running and it secognise USB mouse and can use it simultanosly with touchpad or ps/2 mouse (when I attach ps/2 mouse toucpad become disabled in BIOS) so at boot time attach PS/2 or use touchpad afer you have been booted up.

if nothig actualy not happening try to install some mouse event catcher and see if it is working.

sorry for my bad english, it was a terible day at work...

Good Luck

I once managed to configure my system so that both my synaptics and mouse worked, but cannot remeber the exact configuration and I'm not sure if I was using Gentoo at all.

My problem is this... synaptics works from the start... and after I install the driver the tapping works also.. but my USB mouse is never recognized... I recompiled different kernels with different options at least a dozen times... USBVIEW only shows that USB is a NEC chipset.

I once saved my xorg config when it was working... and it looks like something this:
Synaptics Touchpad "AlwaysCore"
Mouse0 "CorePointer"

Input Device Mouse0
Driver mouse
Protocol IMPS/2
Device /dev/input/mice

I now use the latest kernel 2.6.8-rc2, emerged xorg, manually instaled KDE 3.2.91...

I have a Compaq Presario 2825... can someone please tell me if he managed configure it so that both devices work.

Do you see your USB mouse in /proc/bus/input/devices? (post output of 'cat /proc/bus/input/devices' please)

Ok, do you have all your USB modules loaded (uchi_hcd || ohci_hcd and hid)?

Could you do "grep CONFIG_USB .config"?

My usb mouse (Kennsington) works fine with my synaptics touchpad...and are both usable interchangably. The USB mouse even activates on hotplugging.

Look here for the way I configured it...that is assuming your USB setup is configured correctly:

Make sure you configure the X conf file's "ServerLayout" section like this:

Thanks a lot DTOR.... I have gone through all kinds of tutorials, forums, and nov finallllllllllly I got the USB mouse working. Can you just tell me what this OHCI, EHCI and UHCI translate into in the MENUCONFIG ?

Thanks a lot again! :lol:

Look here:

and here:
