https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=244339 --- Comment #6 from Michael Gmelin <grembo@FreeBSD.org> --- (In reply to Jan Beich from comment #5) Here is a good howto describing how to use usbhidaction(1), which is part of base. https://forums.freebsd.org/threads/howto-using-multimedia-keys-from-uhid-4-devices.24069/ I followed it to construct a little test case on a little Cherry keyboard (vendor 0x046a product 0x0023) that provides media keys over uhid, unfortunately this didn't just work out of the box with this keyboard: # usbhidctl -f /dev/uhid1 -r Report descriptor: Collection type=Application page=Consumer usage=Consumer_Control Input rid=1 pos=0 size=16 count=1 page=Consumer usage=Unassigned Array, logical range 0..1023 End collection Collection type=Application page=Generic_Desktop usage=System_Control Input rid=2 pos=0 size=1 count=1 page=Generic_Desktop usage=System_Power_Down, logical range 0..1 Input rid=2 pos=1 size=1 count=1 page=Generic_Desktop usage=System_Sleep, logical range 0..1 Input rid=2 pos=2 size=1 count=1 page=Generic_Desktop usage=System_Wake_Up, logical range 0..1 End collection Total input size 3 bytes Total output size 0 bytes Total feature size 0 bytes Reading keys is possible, but it's all part of that Unassigned Array above: # usbhidctl -f /dev/uhid1 -r -a -l Report descriptor: Collection type=Application page=Consumer usage=Consumer_Control Input rid=1 pos=0 size=16 count=1 page=Consumer usage=Unassigned Array, logical range 0..1023 End collection Collection type=Application page=Generic_Desktop usage=System_Control Input rid=2 pos=0 size=1 count=1 page=Generic_Desktop usage=System_Power_Down, logical range 0..1 Input rid=2 pos=1 size=1 count=1 page=Generic_Desktop usage=System_Sleep, logical range 0..1 Input rid=2 pos=2 size=1 count=1 page=Generic_Desktop usage=System_Wake_Up, logical range 0..1 End collection Total input size 3 bytes Total output size 0 bytes Total feature size 0 bytes usbhidctl: hid_get_report(rid 1): Device not configured Consumer:Consumer_Control.Consumer:Unassigned= Generic_Desktop:System_Control.Generic_Desktop:System_Power_Down= Generic_Desktop:System_Control.Generic_Desktop:System_Sleep= Generic_Desktop:System_Control.Generic_Desktop:System_Wake_Up= Consumer:Consumer_Control.Consumer:Unassigned=0 Consumer:Consumer_Control.Consumer:Unassigned=234 Consumer:Consumer_Control.Consumer:Unassigned=0 Consumer:Consumer_Control.Consumer:Unassigned=233 Consumer:Consumer_Control.Consumer:Unassigned=0 As you can see, there's a problem getting the hid_report for rid 1. Good news is, that it still reports key events (234 and 233 are "vol down/vol up"). In theory, writing rules should be possible, e.g. # cat myconfig Consumer:Consumer_Control.Consumer:Unassigned 234 0 mixer vol -10 Consumer:Consumer_Control.Consumer:Unassigned 233 0 mixer vol +10 In practice this doesn't work, as the range is limited by usbhidaction: # usbhidaction -f /dev/uhid1 -c myconfig -v PARSE:1 Consumer:Consumer_Control.Consumer:Unassigned, -1, 'mixer vol -10' PARSE:2 Consumer:Consumer_Control.Consumer:Unassigned, -1, 'mixer vol +10' report size 3 system 'mixer vol +10' Setting the mixer vol from 75:75 to 85:85. system 'mixer vol -10' Setting the mixer vol from 85:85 to 75:75. The values are cut to -1. So pressing media keys always executes both actions, not useful (in the example pressing any of the media keys will issues both commands). Looking at the code, I hacked in a workaround: # cat /usr/src/usr.bin/usbhidaction/usbhidaction.c | \ sed "s/range = 1/range = 0/g" >myhidaction.c # cc -o myhidaction myhidaction.c -lusbhid With this patch we can now configure actions. In this example, very basic volume control and controlling audio/cmus (this all runs as root, not ideal, but left out for simplicity): # cat myconfig # voldown Consumer:Consumer_Control.Consumer:Unassigned 234 0 mixer vol -10 # poor man's mute Consumer:Consumer_Control.Consumer:Unassigned 226 0 mixer vol 0 # volup Consumer:Consumer_Control.Consumer:Unassigned 233 0 mixer vol +10 # prev Consumer:Consumer_Control.Consumer:Unassigned 182 0 cmus-remote --prev # play/pause Consumer:Consumer_Control.Consumer:Unassigned 205 0 cmus-remote --pause # next Consumer:Consumer_Control.Consumer:Unassigned 181 0 cmus-remote --next # ./myhidaction -c myconfig -f /dev/uhid1 -v PARSE:2 Consumer:Consumer_Control.Consumer:Unassigned, 234, 'mixer vol -10' PARSE:4 Consumer:Consumer_Control.Consumer:Unassigned, 226, 'mixer vol 0' PARSE:6 Consumer:Consumer_Control.Consumer:Unassigned, 233, 'mixer vol +10' PARSE:8 Consumer:Consumer_Control.Consumer:Unassigned, 182, 'cmus-remote --prev' PARSE:10 Consumer:Consumer_Control.Consumer:Unassigned, 205, 'cmus-remote --pause' PARSE:12 Consumer:Consumer_Control.Consumer:Unassigned, 181, 'cmus-remote --next' report size 3 system 'cmus-remote --pause' PARSE:2 Consumer:Consumer_Control.Consumer:Unassigned, 234, 'mixer vol -10' PARSE:4 Consumer:Consumer_Control.Consumer:Unassigned, 226, 'mixer vol 0' PARSE:6 Consumer:Consumer_Control.Consumer:Unassigned, 233, 'mixer vol +10' PARSE:8 Consumer:Consumer_Control.Consumer:Unassigned, 182, 'cmus-remote --prev' PARSE:10 Consumer:Consumer_Control.Consumer:Unassigned, 205, 'cmus-remote --pause' PARSE:12 Consumer:Consumer_Control.Consumer:Unassigned, 181, 'cmus-remote --next' system 'mixer vol +10' Setting the mixer vol from 20:20 to 30:30. system 'mixer vol +10' Setting the mixer vol from 30:30 to 40:40. system 'mixer vol +10' Setting the mixer vol from 40:40 to 50:50. system 'mixer vol +10' Setting the mixer vol from 50:50 to 60:60. system 'mixer vol +10' Setting the mixer vol from 60:60 to 70:70. system 'mixer vol +10' Setting the mixer vol from 70:70 to 80:80. system 'mixer vol +10' Setting the mixer vol from 80:80 to 90:90. system 'cmus-remote --pause' system 'cmus-remote --pause' So that's good enough for me for demonstration purposes. I hardly ever use that keyboard, but I thought leaving this here still might be useful. -- You are receiving this mail because: You are the assignee for the bug.home | help
