Hello,

I am trying get USB keyboard worked on AM/DM37x EVM for Android 2.2.

Do I need to change any configurations? Am I missing something?

Thanks,

You first need to make sure your Linux kernel supports USB host and has the appropriate USB HID class driver and layout for supporting your keyboard. Once your keyboard is working under Linux, you probably need to adjust Android's configuration to point to the keyboard's input device.

As per the TI Android DevKit user guide : http://processors.wiki.ti.com/index.php/TI-Android-FroYo-DevKit-V2.2_UserGuide, you need a self-powered USB hub to be able to use USB Keyboard/Mouse.

VIshveshwar,

Even if I use the self powered USB HUB, do I need to change my defconfig, or the default defconfig for omap3_evm_android_defconfig should work as it is?

Cause, in the url it says for AM35x and Beagleboard only. On my AM/DM37x I can use the keypad but I want to verify the generic USB keyboard.

Thanks,

The settings in omap3_evm_android_defconfig work fine for USB Keyboard. No need to change anything.

Good catch about the note in the user guide. I will try to get that updated.
