Yes, I do ignore this e-mail address, but not the mailing list. I read it on another e-mail address but post using this one. It is my way of keeping spam down.

I agree. The kernel is indeed in the vanilla kernel sources. However, it is not installed with the fedora kernel.
So why does this matter? The MS Surface Type Cover 3 is not recognized at all with a Fedora 22 installation. It is recognized however, in distributions like kUbuntu. There, the dmesg gives:
[ 1.866285] usb 1-3: new full-speed USB device number 2 using xhci_hcd
[ 1.994694] usb 1-3: No LPM exit latency info found, disabling LPM.
[ 1.996342] usb 1-3: New USB device found, idVendor=045e, idProduct=07e2
[ 1.996346] usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 1.996349] usb 1-3: Product: Surface Type Cover
[ 1.996351] usb 1-3: Manufacturer: Microsoft
Such a dmesg does not show up with Fedora 22 LiveCD.
So I looked this up:
~$ sudo dnf provides */hid-ids.h
Last metadata expiration check performed 3:56:27 ago on Tue Jun 30 08:06:19 2015.
kcbench-data-4.0-0.1-16.fc22.noarch : Kernel sources from 4.0 to be used by
: kcbench
Repo : fedora
You can see that the file is in kcbench-data (which, btw, is 525 M addiitionally (!) when installed).
I just wonder why the files/drivers are in the kernel (from kernel.org) but are not there in the Fedora 22 kernel. They seem to be there in the Ubuntu kernels.
Please let me know if I have still not been clear. I am happy to explain (and test). I would like to use F22 on my Surface Pro 3).
Best wishes,
Ranjan
