Description Vit Pelcak 2015-02-09 11:22:17 UTC

I have upgraded kernel from gentoo-sources 3.17.7 to 3.17.8-r1 and since then after boot mouse Logitech G9X doesn't work.

If I'm lucky, I have to pull it off andf than back. Then sometimes it starts working.

I get this in /var/log/messages:

Then this message pops out, mouse works. When there are no error: -16 in message, it does not. Its LED lights are on all the time.

I tested in BIOS, Windows 7 and Ubuntu 14.04 and Gentoo on kernel 3.17.7 where this mouse works. Gentoo kernel 3.17.8 and 3.18.6 have this issue. I also tried 3.18.6 vanilla where I suffer from the same issue. So it looks like regression introduced with 3.17.8.



Reproducible: Always

Steps to Reproduce:
1. Have mouse Logitech G9X in USB
2. Boot kernel 3.17.8 and older
3. Mouse doesn't move although its LEDs are on.

Are you plugging it into a hub?

Can you try different usb ports to see if that helps?

Would you consider doing a git bisect to figure out the problem commit between the first non-working kernel and the last working kernel?
