[gentoo-user] Logitech cordless

List members -

I am trying to use a Logitech cordless keyboard and mouse with my
gentoo based laptop.  When I try to boot into linux the cordless
receiver is never enabled.  After doing some research on google it
appears that the easiest solution is to use a USB to PS2 adapter for
the usb connection, but unfortunately that will not work for me as I
only have one ps2 slot.  Does anyone know if there is a kernel option
or a third party driver that I could install to enable my cordless
keyboard and mouse.

Thanks everyone for all of your help over the last few days.

regards,
James

This may be a stupid question, but is your USB support enabled in your
kernel?  Certain types of support are not enabled by default.  If you like,
send your laptop model and make so I can see which type you'll need to
compile in.

Also, I assume you're using UDEV?

AFAIK you only need USB HID support. (Device Drivers->USB
Suppport->USB Human Interface Device (full HID) support).  Make sure
it is =y to build into the kernel.  My system at home uses no PS/2
devices at all.

If you want a hardware solution, generally a PS2 splitter will do the
trick.  It is common to use these with laptops to allow a PS/2
keyboard and a PS/2 mouse to be connected to the same port, although
there is nothing really 'special' about the splitter.  Just ask your
local computer store for a PS/2 Y-splitter.

never?  Did you wait until X boots?

using ps2 shouldn't be necessary.

The fact that it's cordless doesn't matter.  The dongle pretends to be
the keyboard and mouse on their behalf...

I can think of three things you may need to do:

1. you need to turn on usb legacy in the bios (never understood why it
was called "legacy", but you need this to use usb keyboards before the
OS loads the usb drivers, eg in grub)

2a. you need hotplug / coldplug or whatever udev has replaced it with.
I'm using ~x86 which obsoletes hotplug and coldplug in favour of udev,
but if you're using x86, hotplug and coldplug may still be around.
OR
2b. Instead of coldplug, you could just load the usb modules
automatically on boot with /etc/modules.d/...

3. You might not have compiled usb support into your kernel, or maybe
you left out usbhid.

let me know how you go with those pointers.
