Hi Everyone,

I just getting start with my new board.Android is running up.
and going through the documents "DragonBoard 410c Android User Guide"
In the 5th step , its failing. if i connect the use to Board , Android studio detecting as Unknown Android Device. I updated the “android_winusb.inf” file also.

Hi Ashok,

Did you enable developer option’s and usb debugging in Android settings.
Keyboard and mouse does not work if you connect mini usb(i have no idea).which OS your are using (Windows/Ubuntu)?

Hi Ramesh,

Yes i enabled, still it detecting as “Unknown Android device” but i am able to Debug and Download the APK files so no issue in it.

Im running Android studio on Windows 7 machine, when i connect mini usb to laptop, Keybaord and mouse not working and after disconnecting the mini usb its started working . anyhow this issue is not major issue for me.

Thanks,
Ashok R

Hi @Asokfair:

The 410 processor only has one USB port. This port can operate in either host or device mode. There is a switch between the onboard hub (host mode) and the micro-USB connection (device mode). When you plug in mini-USB, the switch automatically connects you to the mini-USB connector in device mode and the host ports are disabled. This is expected behavior for the 410c board as described in the documentation.

I am facing the same issue.

I am building an android application, and debugging.

How can i debug if both mini usb and mouse don’t work?

I need to click a button to invoke something and then debug code? Is their some work around?
