Problem To Test USB OTG as HOST using a USB Mouse

[Anirban Roy Choudhury]

Hi all,

When I am testing USB OTG as host using a USB Mouse at that time when I am giving
the command "vtest /dev/input/event0" It is givin following error

[root@beagleboard mmc]# evtest /dev/input/event0
Input driver version is 1.0.0
Input device ID: bus 0x0 vendor 0x0 product 0x0 version 0x0
Input device name: "triton2-pwrbutton"
Supported events:
  Event type 0 (Sync)
  Event type 1 (Key)
    Event code 116 (Power)
Testing ... (interrupt to exit)

After that console is hanged.
So, How this problem will be fixed.

Thanks & Regards
Anirban Roy Choudhury

Hi all,

I have soldered the pin 4(ID) and pin 5(GND) of OTG to keep the board in host mode,
How to be sure that it is working under host mode. I am using IO Gear 4 port USB HUB.
Hub is getting power from beagle board without externel power to the HUB and even mouse
is getting power too.

But still it is giving output as

[root@beagleboard /]# cd /mnt/mmc/

[root@beagleboard mmc]# evtest /dev/input/event0
Input driver version is 1.0.0
Input device ID: bus 0x0 vendor 0x0 product 0x0 version 0x0
Input device name: "triton2-pwrbutton"
Supported events:
Event type 0 (Sync)
Event type 1 (Key)
Event code 116 (Power)
Testing ... (interrupt to exit)

and mouse click event is not happening.

Thanks & Regards

What makes you think event0 is the mouse?

Especially since it says that it's the user button, not a mouse.

The BeagleBoard USB OTG port can only source 100 mA. This is barely
enough for one USB device, and usually is not enough for reliable
operation of a hub plus a device. I recommend trying external power
for the hub. Many unpowered hubs have a 5V power jack. Be sure to
use a well-regulated +5V supply and be sure that the plug has the
correct polarity for your hub. Also, try the mouse alone without a
hub.

The way I test whether the BeagleBoard USB OTG port is in host mode on
my Rev B4 board is to see if pin 1 of the OTG connector is at +5V. R5
is a good place to probe it.

There are useful OTG hints at the eLinux wiki http://elinux.org/BeagleBoard#OTG
and FAQ http://elinux.org/BeagleBoardFAQ#USB_OTG_connection.

Hi John,

we are using Rev B5 board and whatever you told we have checked it already
but that is also not working and giving
same output as previous.

Thanks & Regards,
