Logitech h600 USB wireless headset causes segfault

[smaug42]

I have just updated my Sabayon and now if I plug in my h600 Logitech USB wireless headset, X falls over with a segfault. I have an older Logitech Clearchat USB wireless headset that works fine (ie no segfault) when I plug it in.

I've done some digging and not found anythign Sabayon specific about this, but I have found this: https://bugs.launchpad.net/ubuntu/+sour ... bug/973297 which appears to be the identical problem... note that the "fault at address" changes from one boot to the next depending on if I plug in the USB dongle before or after boot.

This is the relevant output from the Xorg log file.

Any way around this? Or is it a known problem?

[smaug42]

After digging around, it seems that this is my problem... https://packages.sabayon.org/show/xf86- ... 5,standard So how does a newbie user roll back to the previous version (you know... so my headset doesn't segfault and crash X every time I want to use it)?

[wolfden]

So this is a known issue with that hardware and driver?

To revert to older driver you would have to use portage to emerge it than mask it in entropy. So something like

emerge --sync
emerge x11-drivers/xf86-input-evdev-xxx << replace xxx with version needed

equo mask xf86-input-evdev

If you change kernels in the future you will have to remerge the driver again.
