So unless you see this message repeated constantly in /var/log/messages you may safely ignore it. If it does show constantly then how you disable it depends on the device driver. The common example, for the Realtek ums_realtek driver only, is to supply the additional modprobe switch "ss_en=0". If that doesn't work for your driver first look in your distributions and then the kernels bug tracker for similar fix requests before opening on yourself.
Yes this message kept repeating a few times when I tried to do various things.
Fedora 20 was a recent install, so in addition to a few other things I did to the computer, I went on Intel and Dell and downloaded all compatible drivers, I installed KDE for Netbooks, I installed a few packages with yum, and I did yum update/upgrade and now it does not appear anymore.
I think the message was appearing when I was trying to install RPM Fusion free and non-free in order to get the wifi working, and in order to do that I needed to upgrade my kernel to 3.17 (it was 3.11 before (not sure those are the correct versions)). After that I rebooted and did yum upgrade/update, and then after a second reboot it stopped appearing.
If you know why, I would love to know, but thanks anyway for your response.
