External keyboard not recognized by laptop

[gustaf]

I have an Apple Extended ADB Keyboard (the kind with mechanical key switches) connected to a Thinkpad X220 Tablet via a Griffin iMate USB to ADB adapter. This keyboard isn't playing nice with OpenBSD.

Before you run away FAST, please note: I am NOT asking for help with this truly esoteric (and beloved) piece of hardware.

For reasons that will (hopefully) become clear, I believe there might be a software solution that involves reconfiguring something that loads before xinit(1).

To make sure it really is the keyboard and not some other piece of attached hardware or my window manager, I disabled ~/.xinitrc and powered-off the laptop, then disconnected all external hardware except the ADB keyboard and adapter before restarting and booting into the console. This is my usual way of running X. I don't use a graphical log-in manager.

I tried logging in. The ADB keyboard didn't respond. I pressed some keys and nothing appeared on the screen. I tried escaping to an alternate console (Ctrl-Alt-F2, etc.). Same non-response.

The laptop keyboard worked. I could log in and run X, and I could escape to an alternate console.

Here's where it gets wierd.

After I have run xinit(1) once, the keyboard problem disappears.

When I quit X and return to the console, I can still enter text from the ADB keyboard and use the alternate consoles.

I tried two other keyboards: a native USB, and a PS2 with a USB adapter. The problem only occurs with the ADB keyboard.

I ran dmesg(8) immediately after booting, immediately after starting X, and immediately after quitting X. The result was the same in all three cases -- the Griffin iMate and converted keyboard are clearly being recognized by the kernel:

Since I haven't reconfigured anything in wscons(4), I don't have an /etc/wsconsctl.conf file.

wsconsctl(8) shows two keyboards, "pc-xt" (which I presume is the laptop) and "usb" (which I presume is the converted ADB keyboard), even before starting X:

$ doas wsconsctl -a

keyboard.type=pc-xt
......................
keyboard.encoding=us
......................
keyboard1.type=usb
......................
keyboard1.encoding=us
......................
display.type=inteldrm
display.width=1280
display.height=768
display.depth=32
display.emulations=vt100
display.screentypes=std
display.focus=4
display.brightness=100.00%
display.screen_on=250
display.screen_off=0
display.vblank=off
display.kbdact=on
display.msact=on
display.outact=on

Looking at /usr/include/dev/wscons/wsconsio.h, I can see that Apple ADB keyboards are a recognized type:

/* Get keyboard type. */
#define WSKBDIO_GTYPE           _IOR('W', 0, u_int)
.......................................................
#define         WSKBD_TYPE_PC_XT        3       /* PC-ish, XT scancode */
..........................................................................
#define         WSKBD_TYPE_USB          5       /* USB, XT scancode */
..........................................................................
#define         WSKBD_TYPE_ADB          10      /* Apple ADB keyboard */
..........................................................................

The purpose of the iMate is to convert ADB to USB, so this keyboard should be treated as just another USB device, but support for ADB is also available, if needed.

Would it be helpful to post /var/log/Xorg.0.log? I'm not sure what to look for in this file; I didn't see anything obvious when I inspected it.

Troubleshooting questions:

• Shouldn't quitting X completely return the system to a non-X state, with all associated hardware restrictions?
• What happens when I run xinit(1) that enables the external ADB keyboard to still function even after I quit X?

It seems like I should be able to reconfigure something so that the converted ADB keyboard is recognized during the boot sequence or find out what X is doing to the keyboard configuration and somehow move that bit of information into the boot sequence.

It's also possible that I have completely misinterpreted the problem.

I hope there's a way to fix this. I'd really like to get this keyboard fully working.

Many thanks to anyone who can offer assistance.

...but support for ADB is also available, if needed...

I believe this recognition is for the macppc architecture. You will find ADB keyboards mentioned in http://www.openbsd.org/macppc.html but not in http://www.openbsd.org/amd64.html.

[jggimi]

And that's confirmed. This is only used by sys/dev/akbd.c, which is only compiled with sys/arch/macppc/{GENERIC,RAMDISK} kernels. The akbd(4) man page describes the driver.

[gustaf]

After reading your responses and re-reading my original post, I can see that I wasn't very clear about some things.

I have examined the output of dmesg(8) and wsconsctl(8) more closely. In both cases, there are two recognized keyboards (PC and USB). "PC" is the laptop keyboard; "USB" is the converted Apple keyboard.

$ dmesg

The strange thing is that the Apple keyboard/Griffin iMate combination works flawlessly, but only after the initial run of X. For some reason, the keyboard continues to work even after I quit X and return to the console. There is something about starting X that enables this keyboard.

How do I find out what X is doing that makes it possible for this keyboard to function and what do I need to configure to enable this keyboard at boot time?

I hope these are the right questions. My goal is to log in and work from the console immediately after booting without having to resort to the laptop keyboard.

/var/log/Xorg.0.log may provide some information about keyboard attachment and keyboard drivers that it selects.

... and what do I need to configure to enable this keyboard at boot time?

Are you interested in developing a software solution for your keyboard yourself? If so you may be able to gain insight through a review of the source code of the keyboard drivers noted in the log. Then you can compare this to the ukbd(4) kernel driver source code.

If you're not interested in a source code review (and developing your own patch), consider posting a problem report to the bugs@ mailing list.

This is turning into a bigger project than I have time for; I may come back to it eventually.

In the meantime, I have enabled xenodm(1).

The X Window System FAQ and /usr/X11R6/README were also helpful.

Thanks for helping me sort this out.
