I have been reading the bug reports about the problem with initializing Logitech wireless devices using the current stock Centos 7 kernel. It's my understanding that this issue will be fixed in the Centos Plus kernel.
However, I suspect that the issue will also be fixed at some point when Red Hat get around to fixing their kernel as well.
My main computer has a Logitech wireless mouse that's likely affected by the bug, though I haven't tried it yet to verify that.
One of these days I intend to get around to installing Centos 7 on this computer, and this will then become an issue.
If I install Centos 7 and then the Centos Plus kernel to get the Logitech bug fix, what happens when the stock Centos 7 kernel also gets the bug fix applied? Will a standard "yum update" automatically find and download the new stock Centos 7 kernel and set everything up to it instead of the Centos Plus kernel?
I suppose I could go and hunt down a different mouse to use on this computer until the issue is resolved upstream, too.

Look in /etc/sysconfig/kernel. There is a line:
DEFAULTKERNEL=kernel
For the default kernel, you can select between kernel and kernel-plus by adjusting that option.

My first mouse, many years ago with an AT plug, cost me GBP 56 (circa USD 90). These days I use on desktops, laptops, notebooks (all running Centos of course) etc. mice costing circa GBP 3.00 including postage from China. These cheap mice simply plug into a spare USB socket.

Get a cheap mouse from China - plug it into a USB socket then carry-on working normally.
I found that you have to get a different keyboard even to complete the install. I thought that was interesting since this wireless keyboard works in the early BIOS settings, e.g. F12 for boot menu, etc. It was interesting to me that at a later time when the kernel with this bug loads, the keyboard stops working. I found this to be true whether using the graphic or text install. CentOS 7 looks great although it's unfortunate that this situation exists since with this keyboard a novice could be discouraged from installing due to what appears as a hang on the language selection screen. It's not a hang, it's just that the silly keyboard and mouse aren't working.
Enjoying my preview of CentOS 7, but lamenting missing system-config-lvm. I know that was dropped after fc 18. Is it gone from CentOS and RHEL as well?

My Logitech wireless mouse model M510 is NOT affected by this bug. I just plugged it into my laptop that I have Centos 7 installed on, and it works perfectly.

M510 is as affected as anything else with the tiny unified receiver. It's a race condition though, so sometimes it works, sometimes it doesn't. It's more likely to happen on boot, I think. From what I can recall of the Fedora days with the relevant kernels, un- and re-plugging the receiver or un- and re-loading the module would typically get things working again, though it could take a few attempts.
