Mouse/Keyboard (USB OTG) not available in 'QNX Smart Energy Reference Design'
Hi, everyone!
I'm not sure if this is the right place to ask, but can you help me with the following:
I'm trying to run the 'QNX Smart Energy Reference Design' on Beagleboard rev. C3.
How to get the mouse running in this project? I connect the Beagleboard via a USB hub connected to the USB OTG port
which powers the board. I also connect the serial port to have a console. Unfortunately the mouse and keyboard attached
to the hub are dead.
Here is the log from the start-up procedure:

Re: Mouse/Keyboard (USB OTG) not available in 'QNX Smart Energy Reference Design'
Hi Yassen,
It appears that the USB devices are not recognized by QNX on the Beagle (you mentioned mouse/keyboard, but also network
as seen in the log 'ifconfig: SIOCGIFFLAGS en0: No such device or address', assuming you have a network dongle connected
to the hub as well) - this is a common problem with this target.
For devices connected through the USB OTG port on the Beagle board, you must ensure the following:
- your USB hub is self-powered (the Beagle can't support a bus-powered hub on this port).
- when you power-on the beagle:
1. first press & hold down the 'USER'/'S1' button on the board;
2. plug in power via the 5V DC port on the Beagle;
3. release the 'USER'/'S1' button when you see the Beagle splash screen,
or after about 5 seconds.
If your USB devices still aren't working, you can verify from the serial command-line if the devices are recognized
using the following command (the output below lists the various devices that are seen on the USB bus):
# /qnx-ia/armle/sbin/usb
USB 0 (OMAP3530) v1.10, v1.01 DDK, v1.01 HCD
Device Address : 1
Vendor : 0x05e3
Product : 0x0608 (USB2.0 Hub)
Class : 0x09 (Hub)
Subclass : 0x00
Protocol : 0x01
Hub Number Ports : 4
Hub Characteristics : 0x00e4 (Ganged power, Compound, Global over-current)
Hub Power On->Good : 100 ms
Hub Power Requirements : 100 mA
Device Address : 2
Vendor : 0x05e3
Product : 0x0608 (USB2.0 Hub)
Class : 0x09 (Hub)
Subclass : 0x00
Protocol : 0x01
Hub Number Ports : 4
Hub Characteristics : 0x00e0 (Ganged power, Global over-current)
Hub Power On->Good : 100 ms
Hub Power Requirements : 100 mA
Device Address : 3
Vendor : 0x0b95 (ASIX Elec. Corp.)
Product : 0x7720 (AX88x72A)
Class : 0xff (Vendor-specific)
Subclass : 0xff
Protocol : 0x00
Device Address : 4
Vendor : 0x0596 (3M)
Product : 0x0001 (3M USB Touchscreen - EX II)
Class : 0x00 (Independent per interface)
If you don't see any devices listed using this command, then there is still a problem with your USB hub. Often, you need
to physically remove power from the board, make sure you're holding the USER button down, apply power, and don't
release the USER button until the boot sequence is fully initiated (ie, you see the Beagle splash screen, or your serial
output indicates that the demo is loading).

Re: Mouse/Keyboard (USB OTG) not available in 'QNX Smart Energy Reference Design'
Hi, Ben!
Thank you for the input. I have already tried all of this without success. The mouse is optical and lights up but
doesn't work at all. The keyboard is dead as well. With the WiFi adapter it is the same, but if I fix the mouse, the
same solution should fix the other usb devices I think.
My USB hub is self powered using a 2.1A / 5V DC supply. The Beagleboard is powered by the hub, through the OTG port and
NOT through the dedicated supply input. I doubt this can be a problem because I have tested the same configuration with
Angstrom linux and it worked properly.
I also keep pressed the USER S1 button while booting. Maybe I forgot to mention that the start-up log I've posted was
exactly from this case. This is the whole log on the screen.
Running the 'usb' command founds no usb devices as below:
---- result ----
# /qnx-ia/armle/sbin/usb
USB 0 (OMAP3530) v1.10, v1.01 DDK, v1.01 HCD
---- end of result ----
I have also tried to run both the USB OTG Host and EHCI Host using the following command:
# io-usb -domap3530-mg ioport=0x480ab000,irq=92 -dehci-omap3 ioport=0x48064800,irq=77,verbose=5
which I have found on this page:
http://community.qnx.com/sf/wiki/do/viewPage/projects.bsp/wiki/TiOmap3530evm1.0.020080109ReleaseNotes?showDetails=true
No luck so far. Any other suggestions?

RE: Mouse/Keyboard (USB OTG) not available in 'QNX Smart Energy Reference Design'
This really looks like the common problem we see with the Beagle board
(no devices showing up on USB OTG bus), and you're right, once QNX does
recognize the devices on the bus, they should all work. It's nomally
just a matter of holding down the USER button when powering-up the
board, but your configuration is unusual.
So, I suggest, at this point, to try plugging in 5V power directly to
the Beagle (in addition to powering the hub). Powering the Beagle via
the USB OTG port is not a use case that I've personally ever seen used
here (in fact, my C3 board will not power-up at all until I plug into
the 5V DC port - maybe there is a jumper config to enable this?). That
configuration may be valid using another BSP, but I suspect it may not
be supported by our BSP (although I can't find any reference to this
explicitly, I know the USB driver is sensitive to the power
configuration, and of course to the USER button). The recommended power
adapter is: 'USB A Male to 5.5mm Power Plug Cable', which you can order
from here: https://specialcomp.com/beagleboard/order.htm.
I will also refer you to the latest BSP release notes here:
http://community.qnx.com/sf/wiki/do/viewPage/projects.bsp/wiki/Nto641TiO
map3530Beagle1.0.0Releasenotes. Where did you find the older release
notes?
Could you also point me to where you got the Smart Energy demo download
from?
Thanks,
Ben

Re: RE: Mouse/Keyboard (USB OTG) not available in 'QNX Smart Energy Reference Design'
Yassen,
Something else to consider is the cable you're using to connect the USB hub. I'm just wondering if you're using a cable
that supports powering the board, but does not allow the QNX driver to communicate properly with the hub. As mentioned
in the release notes, the required cable is mini A to mini B usb cable (A-side going into the Beagle), which is
available for order here: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=WM17494-ND.

Re: RE: Mouse/Keyboard (USB OTG) not available in 'QNX Smart Energy Reference Design'
Hi, Ben!
Thank you very much. Your suggestion seems to solve the problem although I couldn't explain fully the case for myself...
The cable I've used is mini A to mini B which function is actually to short pins 4 and 5 on the Beagle USB OTG port
(that's mini A) and the hub delivers power to the board through the USB. Using other cables is possible with the same
hub if you solder pins 4 and 5 on the port itself or solder the J6 pcb pads on the Beagleboard (valid for rev. C3; J6 is
on the opposite side of the board just beneath the USB port). There are no jumpers on the board that are related to the
problem. The sole change I've made to the board is soldering a 22uF capacitor in parallel with the C97 capacitor to
solve the known problem with the noise on the 1.8V rail that exists with the rev. C3 board.
Finally, to run the USB devices (mouse, keyboard, etc.) it turns out that powering the Beagleboard through the dedicated
5V input AND pressing the User1 button is crucial. Now everything looks fine.
I've got the "Smart Energy Reference Design - TI OMAP3530 BeagleBoard with mouse" from
http://www.qnx.com/download/feature.html?programid=20707
which is accessible from the main QNX website: "www.qnx.com" -> "Downloads" -> "Reference Designs + Demos" -> "TI
BeagleBoard (OMAP 3530) with mouse"
Best regards,
Yassen
