Hi All, I was asked to send here a bug I originally posted at https://bugzilla.kernel.org/show_bug.cgi?id=198155 . I've been using for a couple of years these Roccat drivers https://sourceforge.net/projects/roccat/ with Fedora and a Nyth USB mouse https://www.roccat.org/en-GB/Products/Gaming-Mice/Nyth/ that has a series of configurable keys. The keys can be used as a "second keyboard", e.g. to trigger shortcuts. I've been using that, for example, to quickly switch Gnome workspace, triggering Win+1, Win+2... Since upgrading to kernel 4.14.3-300 - the latest distributed with Fedora 27 - the Nyth drivers apparently can't "press" the Win key any more. E.g. if I press the mouse keys in a console, I don't switch workspace, but actually see 1, 2... The Win+1, Win+2 etc. shortcuts work nicely from my Thinkpad T450s keyboard and the external Lenovo USB keyboard. If I go back to kernel 4.13.16-302, everything works back again. I don't have a spare laptop to test the issue with more recent builds. Thanks.
