Hi!
I have a couple of questions about USB.
I recently bought a new USB keyboard, a Logitech K120. When
attaching this to a FreeBSD system, however, it is detected as a
hid device (attaching to uhid) rather than a keyboard (attaching to
ukbd). The keyboard works fine, but I'm just curious as to why it
doesn't use ukbd.
The output from usbconfig for this keyboard is:
Hi,
It seems the UHID driver needs to be synced with UMS and UKBD
regarding the
detection logic. Can you try the attached patch and report back.
--HPS
One more thing to check:
/etc/devd/usb.conf
Is perhaps auto-loading uhid before ukbd, and that might also be part
of the
issue.
Hi!
Having ukbd in the kernel, and not uhid, makes uhid load as a module
during boot and attach to the keyboard, even with your patch. I'm
recompiling the kernel now with uhid as part of the kernel to see if it
makes a difference. I'm not too confortable hacking /etc/devd/usb.conf,
but if you can point me in the right direction I'll have a go at it.
Regards!
Having uhid in the kernel did not make a difference, it attached to the
keyboard (or rather, the keyboard attached to the uhid driver, I guess).
Regards!
Could you dump the configuration descriptor of your device using
usbconfig?
usbconfig -d X.Y dump_curr_config_desc
--HPS
Attached patch contains the dump. From my reading of the USB spec, it
seems that this keyboard has two interfaces, one that detects as a
keyboard, and might be the boot device, and one that's just a regular
hid. I might also be very wrong in this. :)
I have a dump from a keyboard that only attaches to ukbd, if you need
something to compare to. That keyboard, however, believes it's a liteon
keyboard, rather than a logitech keyboard. That, however, is probably
Logitech's fault.
Thank you for helping out!
Regards!
Hi,
You should have one of each, one ukbd, and one uhid.
If you run "usbconfig show_ifdrv" at what interface is the uhid and ukbd
attached.
Make sure both uhid and ukbd is loaded.
Please add a printout, but is_keyboard should be non-zero, before and after my
patch. So uhid is not attaching to the wrong interface, so to speak.
Running usbconfig show_ifdrv shows uhid and ukbd both attached to the
keyboard, both with and without your patch, and the output looks the
same, see attached file. I can't find the is_keyboard flag you're
talking about however, but the keyboard works.
I guess I'm mostly surprised that the keyboard attaches as a HID as
well, so it can be that I'm making a lot of noise about a non-issue.
Thanks for helping out though!
Regards!
