I use MSI Wind U100 laptop. My DMI is:

dmi:bvnAmericanMegatrendsInc.:bvr4.6.3:bd12/01/2009:svnMICRO-STARINTERNATIONALCO.,LTD:pnU90/U100:pvrVer.001:rvnMICRO-STARINTERNATIONALCO.,LTD:rnU90/U100:rvrVer.001:cvnMICRO-STARINTERNATIONALCO.,LTD:ct10:cvrVer.001:

There are some rules that should match my laptop in
/lib/udev/hwdb.d/60-keyboard.hwdb:


keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pn*
keyboard:dmi:bvn*:bvr*:bd*:svnMicro-Star*:pn*
 KEYBOARD_KEY_a0=mute                                   # Fn+F9
 KEYBOARD_KEY_ae=volumedown                             # Fn+F7
 KEYBOARD_KEY_b0=volumeup                               # Fn+F8
 KEYBOARD_KEY_b2=www                                    # e button
 KEYBOARD_KEY_df=sleep                                  # Fn+F12
 KEYBOARD_KEY_e2=bluetooth                              # satellite dish2
 KEYBOARD_KEY_e4=f21                                    # Fn+F3 Touchpad
disable
 KEYBOARD_KEY_ec=email                                  # envelope button
 KEYBOARD_KEY_ee=camera                                 # Fn+F6 camera disable
 KEYBOARD_KEY_f6=wlan                                   # satellite dish1
 KEYBOARD_KEY_f7=brightnessdown                         # Fn+F4
 KEYBOARD_KEY_f8=brightnessup                           # Fn+F5
 KEYBOARD_KEY_f9=search

#
keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pn*U-100*:pvr*
keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pn*U100*:pvr*
keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pn*N033:*
 KEYBOARD_KEY_f7=reserved
 KEYBOARD_KEY_f8=reserved

#
keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pnU90/U100:*
 KEYBOARD_KEY_e4=reserved


The problem is that string
"keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pn*U100*:pvr*" for some reason does
not match my laptop. I tried
"keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pnU90/U100:pvr*", and it worked.
After some tries I found out that if "pn" is followed by "*", match will not
work. So:

doesn't work: keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pn*U100*:pvr*
doesn't work: keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pn*U90/U100:pvr*
works fine: keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pnU90/U100:pvr*
works fine: keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pnU90*:pvr*
doesn't work: keyboard:dmi:bvn*:bvr*:bd*:svnMICRO-STAR*:pn*90*:pvr*

Obviously this is a bug, * should work like expected. I'm on systemd 218,
Gentoo ~x86.
