Description Gianfranco Cecconi 2017-12-13 14:53:17 UTC 
Hi All,

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.x, 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'm putting a reference to this on the drivers' discussion forum, in case the author had suggestions for you. Thanks.

All USB bugs should be sent to the linux-usb@vger.kernel.org mailing
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.
