Subject: Fwd: ehci-pci failed handover

Hello.

I am getting some strange messages when I try to connect a Logitech
m185 wireless mouse to my Pavilion zd8000.

The mouse works in some other machines, and the usb ports of the
pavillion have been tested only with regular pendrives, which work
fine, but nothing else.

When I attach the mouse I get messages like these:

HID stuff is enabled in my kernel, but for what I read in that output
I don't think it's even reaching that stage, is it?

This is gentoo, using linux 3.8.7, I can attach the .config if needed.
Don't want to spam the list. I have used this same mouse in my desktop
(gentoo as well) and it's working nicely.

Can you give me some pointers on how to proceed?

Thanks beforehand for any help, or just for reading :)
