hid_get_item: HID_ITEM_MAXUSAGE should be increased up to 31 to parse the HID report descriptor

I have a ~16 years old Logitech USB keyboard that I use since today. Media keys are not recognize properly, and it is pretty buggy.

# usbconfig -d ugen0.4
ugen0.4: <Logitech Logitech USB Keyboard> at usbus0, cfg=0 md=HOST spd=LOW (1.5Mbps) pwr=ON (100mA)

It currently works with Windows and Linux, and used to work with FreeBSD from 6.2 to 8.

I tried it on two 13.0-RELEASE-p7 setups, but found that it works erratically. It randomly lags and doubles some keystrokes.

Moreover, with Gnome, <super> + <l> does not lock the screen, and media keys do not work.

I tried to catch some input with xev(1) in vain, as these media keys are not "displayed". The same applies with libinput debug-events, media keys are not catch.

Not sure if it is normal, but I have noticed that my keyboard is detected as two devices:

Code: 
event4   DEVICE_ADDED            Logitech Logitech USB Keyboard, class 0/0, rev 1.10/23.00, addr 3 seat0 default group5  cap:k
event6   DEVICE_ADDED            Logitech Logitech USB Keyboard System Control seat0 default group7  cap:k

As expected, gsettings value for these media keys are static (meaning not working):

I have tested another generic keyboard that works perfectly out of the box (included media keys), with all pc tested running FreeBSD 13.0-RELEASE-p7.

dmesg -a returns multiple times:

Code: 
hid_get_item: HID_ITEM_MAXUSAGE should be increased up to 31 to parse the HID report descriptor

Maybe I am wrong, but seems a driver bug and my keyboard is not properly recognized as the report is cropped, being limited to 8 bytes?

Anyway, I tried to compile from sources the hid module to increase HID_ITEM_MAXUSAGE, but opt_hid.h seems missing.

I have also tested iichid driver and tried the HID driver hcons, but again in vain, as I get:

Code: 
driver bug: Unable to set devclass (class: ppc devname: (unknown))

Now I am out of idea now.

I cleaned the sources and managed to build the module.
Code: 
git fetch origin
git reset --hard origin/stable/13

The good:
  • I do not see anymore complaint about HID_ITEM_MAXUSAGE size,
  • Maybe I am wrong, but at least for now, seems there is no more random lags and "double keystrokes" ;
The bad?
  • My keyboard is detected as two devices.
The ugly:
  • <super> + <l> does not lock the screen;
  • Still have this message when I try to enable iichid:
Code: 
driver bug: Unable to set devclass (class: ppc devname: (unknown))
  • Unfortunately, media keys still not work (not showing in xev, libinput, nor in gsettings).

Yes, the bad. There should be at least 3 devices.

It is not clear to me what "enable iichid" means but to get media keys working you should enable usbhid with adding of following lines to /boot/loader.conf:
hw.usb.usbhid.enable=1 usbhid_load="YES"
 
Of course, these are enable, yet media keys are not working (nor <ctrl> + <l> does work properly):
Code: 
hw.usb.usbhid.enable=1
usbhid_load="YES"

Nevertheless, the first made the suspend button working again, even if it is yet marked as static in gsettings.

And "by enable iichid, I mean according to the iichid README". But seems that unloading and loading again the iichid module does no more trigger every time the message:

Code: 
driver bug: Unable to set devclass (class: ppc devname: (unknown))
