MOUSE AUTODETECTION: NEED FEEDBACK FROM EVERYBODY

Message

BarryK · #1 Post by **BarryK** » Wed 05 Apr 2006, 09:01

Everybody who is running Puppy that is!

I'm working on mouse autodetection.
Detection of the USB mouse is fine.

I was doing some research on how to detect a PS/2 mouse, came across a little
bit of information that the PS/2 mouse always uses interrupt 12.
The interrupt assignments are shown /proc/interrupts, that you can open with
a text editor.

True enough, when using my PS/2 mouse, I see this line in /proc/interrupts:

Code: Select all

 12:       2833          XT-PIC  PS/2 Mouse

On the other hand, using my USB mouse (with PS/2 mouse unplugged):

Code: Select all

 12:          0          XT-PIC  SiS 7012

...something else has grabbed that interrupt.

Question 1
But, I need to know that this behaviour is consistent on other PCs.
If you are using a PS/2 mouse, do you get that text string "PS/2 Mouse"
alongside the interrupt 12 line?
If you are using a USB or serial mouse, do you not get that string?

Question 2
What order should mouses be detected?
Should I check for a USB mouse first, as many people will have an external
USB mouse on their laptop and they will want it to override the internal
one?
If there is no USB mouse, then I'll check for PS/2 mouse, failing that, could
just assume it's serial ...as I don't yet have a surefire serial detection method.

People reporting on what they have in /proc/interrupts can help a lot here.

Yes, in my Celeron 400, it is

Code: Select all

12:      29451          XT-PIC  PS/2 Mouse

Will check on one Puppy PC with serial mouse in the office tomorrow.

As to the order, the surest detection should be first (ps/2 as of now), then if it fails, the user may be asked to key in additional information.

But I guess am mostly a desktop user - laptop users may want USB to be detected first. So perhaps if it's a laptop, it should be USB first.

I have a usb mouse and mine looks like this

Code: Select all

 12:          0          XT-PIC  usb-ohci, au8820

I agree with your order of autodection USB, PS/2, Serial.

My thinkpad's trackpoint:

12: 33749 XT-PIC PS/2 Mouse

The laptop also has an external PS/2 port, using the gives the identical:

12: 39431 XT-PIC PS/2 Mouse

(Minor aside, when using an external scroll wheel mouse, the wheel causes the cursor to leap up or down the screen. Since my laptop doesn't have a scroll wheel, it could have been always doing this and I could never tell. Odd, huh?)

Just out of curiosity, what does that "CPU0" column do? It seems to only increase over time.

EDIT: I think I need to have my eyes examined

I read Barry's post wrong. My results are consistent with his thinking: I'm using a USB mouse and therefore interrupt 12 is not being used for a PS/2 mouse - in fact it's not used at all.

As Barry said, USB detection already works.
----------------------------------------------------
Barry, sorry to rain on your parade, but using Puppy 107 and a usb mouse & keyboard on my laptop I get:

Code: Select all

 14:      10662          XT-PIC  ide0
 15:         82          XT-PIC  ide1

Just to be clear, the mouse and keyboard are connected to the laptop through a 2-port bus-powered USB hub.

lsmod shows:

Code: Select all

EDIT: I found this that may help:

or:

         usbmouse
 96-111: hiddev
         hid
  0- 15: usblp
         serial
#

Both of these detect the usb mouse and keyboard.
NB: the "serial" in the list above is a USB-to-serial adapter I use with the laptop to talk to a controller board.

Search order (if possible): USB, PS/2 then serial

Excellent, we have consistency!

Full mouse autodetection coming soon!

Brian C · #15 Post by **Brian C** » Thu 06 Apr 2006, 02:47

Question 2: I would like to see both supported simultaneously. When I'm working on my laptop, I'll often use my USB mouse, but will temporarily change to the trackpad (ID-ed as PS/2) when I hunch over the screen. Or when my (wireless) USB mouse's batteries die.

On the laptop using the trackpad (PS/2)

Code: Select all

 12:       5152          XT-PIC  PS/2 Mouse

On a desktop using PS/2

Code: Select all

 12:       8261          XT-PIC  PS/2 Mouse

I rebooted the laptop with a USB mouse connected but without deleting the "/etc/mousedevice".

The interrupt 12 was still used by the PS/2

After that I did the following
I exited X
deleted /etc/mousedevice
started X again,
selected USB mouse

The interrupt was not being used anymore.

What would happen if I had a mouse without a scroll button and told puppy that I did? If it doesn't (adversely) affect puppy, then we can just assume that all mice are scroll mice and that would allow us to get rid of one other dialog.

jcoder24,
That's a very interesting question. I have previously done that, as I'm often changing mice, and did not notice any ill effects...
maybe though, we need some volunteers to try this with various non-scrollwheel mouses, to confirm no ill effects.
...I've only got 2-button mouses, need to check with 3-button non-scrollwheel, plus serial, usb, ps/2 types, different brands, and weird ones like that MS multi-everything mouse.
