[9fans] Mouse inverted Y-axis

Ok recompiling the kernel after modifying kb.c did the job,
nusb was documented as userspace program so I never thought of it
thanks

cool.

they are userspace programs. but for the keyboard to work on
bootup (so you can enter stuff like the root filesystem
location), they are started from a ram filesystem build into
the kernel image. the files that get build into that ram
filesystem are listed in: /sys/src/9/port/bootfs.proto

that's specific to your 9front.  in the distribution, those
files are listed in the config file bootdir section.

Great.

I discovered it a some time ago when I had needed to fix the wheel direction of my IBM mouse.

Hi all,

was not something changed in Plan9 kernel(?) in the near past related to the mouse wheel scrolling direction?

I still have opposite scrolling direction when scrolling my mouse wheel (even with my patched kb.c). :(

Thanks for any help.

Hi all,

> I still have opposite scrolling direction when scrolling my mouse wheel (even with my patched kb.c). :(

I have found a problem - as usually placed between keyboard and chair. ;)

I made such sequence to install my modification in kb.c:
- cd /sys/src/cmd/usb/kb
- mk
- mk install
- /sys/src/9/pc
- mk 'CONF=pcf'
- cp 9pcf /n/9fat
- reboot
The modification in kb.c was not used.

So I made such sequence to install my modification in kb.c:
- cd /sys/src/cmd/usb (not into kb subdirectory!)
- mk
- mk install
- /sys/src/9/pc
- mk 'CONF=pcf'
- cp 9pcf /n/9fat
- reboot

The modification in kb.c was used.

Sorry for noice... :(

usb is a pain.  i generally rebuild everything from the top
directory.  nuke it from orbit.  it's the only way to be sure!

I see, good to know. Thanks.

In any case I think there is a bug in kb.c.
The function 'ptrbootpvals' seems correct:

	if(c > 3 && ch->buf[3] == 1)		/* up */
		b |= 0x08;
	if(c > 3 && ch->buf[3] == 0xff)		/* down */
		b |= 0x10;

Wheel-up should set the flag 0x08.
Wheel-down should set the flag 0x10.


But the function 'ptrrepvals' seems buggy:
	if(c > 3 && hidifcval(&kd->templ, KindWheel, 0) > 0)	/* up */
		b |= 0x10;
	if(c > 3 && hidifcval(&kd->templ, KindWheel, 0) < 0)	/* down */
		b |= 0x08;

Wheel-up sets the flag 0x10.
Wheel-down sets the flag 0x08.

something's wrong, but is it the code or the comment?

Code.

Have you recompiled the kernel with your modification and installed it in 9fat partition?

ok now im totally lost.

Even if i set x and y to 0 before they get printed to mousein the
mouse still works.

I have no idea how ps/2 works, but couldn't my bios emulate it for usb devices?

So could there be two values set for mousein, one from the kernel and
one by nusb/kb and because of the ps2 emulation the kernel value is
like 3 times bigger then the negative equivalent of the userspace
driver?

Im really guessing here

Hello all,
this is the first mailing list I'm using so bare with me....

I installed plan9 a few hours ago and haven't actually gotten any time with
the
system before.

My usb-mouse (razer deathadder) is somehow inverted on the y-axis,
I tried the mac mighty mouse and it worked flawlessly.

Not having spent any time with plan9 i googled up nusb flipped y to minus y
and
recompiled. Nothing.
I also changed the mouse delta in the kernel to negative and recompiled
still nothing.

Have i missed something pretty obvious? I admire a quick response(using the
mighty mouse is actually worse then the puck one)

Thanks in advance,
Eddi
