USB input device question

QNX Newsgroups (Archives) qdn.public.ddk.usb

Hi everyone

I have a problem getting USB input devices working in our embedded
system (MIPS, Au1500):

I try

devu-mouse &
devi-hirun msys fd -d/dev/usbmouse0 &

but no mouse cursor appears. (Photon is already started an shows phcalc)

I also tried

io-hid -dusb &
devi-hid mouse &

Here a mouse cursor appears, but no motion.

The same problem is with the USB keyboard, not even /dev/usbkbd0 exists
after starting devu-kbd.


USB is obviously working:

usb

Any idea?

After you run “io-hid -dusb” can you run “hidview”
This will show you any installed HID devices.

If the device appears than run “hidview -a”
This will display any data coming from the device.

Thanks,

hidview shows my keyboard (see below), or mouse.
But hidview -a doesn’t show anything, seems like it hangs.

What now?

Are the devices plugged through the hub ?
Does unplugging/plugging devices into the HUB work ?

Does the keyboard/mouse work ok on x86 ?

Can you run the USB stack with “devu-ohci -vvvvvvvvv”
Check the sloginfo output to see if any errors are reported.

doesn’t make any difference.

Does unplugging/plugging devices into the HUB work ?

yes, see sloginfo below

Does the keyboard/mouse work ok on x86 ?

I don’t know, we only use QNX on our embedded system (MIPS).



Can you run the USB stack with “devu-ohci -vvvvvvvvv” Check the
sloginfo output to see if any errors are reported.

Please see below. Apart from the beginning I think it looks ok, doesn’t it?

Another question:
What about devu-mouse and devu-kbd together with devi-hirun? Where is
the difference to io-hid and devi-hid?


Thanks,
Joerg

Ok. This means that the interrupt endpoint for the HUB is working.
Mouse and keyboard also use interrupt endpoints but the devices
don’t appear to be sending any data.

Since both devu-mouse and io-hid isn’t working the problem points
to the USB stack. We’ve tested here with a MIPS board and could
not reproduce this behaviour.

I may need to send you a version of the stack with some debug that
will show if any data is coming from the device.

io-hid/devi-hid is a new architecture being put in place to
better support USB input devices. USB HID devices can get quite complex
and completly describe themselves and the data they send. With io-hid
it will make it easier to write a single driver to manage simple and complex
devices. It also better supports the plug and play nature of the devices.

Ok. This means that the interrupt endpoint for the HUB is working.
Mouse and keyboard also use interrupt endpoints but the devices
don’t appear to be sending any data.

Since both devu-mouse and io-hid isn’t working the problem points
to the USB stack. We’ve tested here with a MIPS board and could
not reproduce this behaviour.

I may need to send you a version of the stack with some debug that
will show if any data is coming from the device.


Any news about the debug version of the stack ?
