How to enable the USB TTY in the SABRE tablet iMX53?

Hello:

I am trying to setup Android Image to have the USB TTY driver. By using the menuconfig, the menu "Device Drivers" -> "USB support" -> "USB Serial Converter support" -> "USB Generic Serial Driver". Save the menuconfig, and build the kernel_imx. I modified the init.rc to add "chmod 0777 /dev/ttyACM*" to change mode. I flash to Android image into Sabre tablet, and power it up. I plug USB cable from the Sabre tablet into Kenetic ARM tower. But I don't see Android enum the USB device.

 

Can anyone who know how to setup Sabre Tablet to support USB TTY?

 

Thank You

Mike

Yes, I anble the USB / Serial General Conversion. I did follow the Freescale Power Point that setup Android USB/Serial COM ("ttyACM0").

 

I am using the USB host connector. The Android is USB Host, and the K53 Kinitic is the device.

Best regards,

I don´t know how to set up USB TTY, bu tit looks like you´re doing the right way (enabling it on kernel).

Are you using the right USB connector (host/otg)?????
