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?
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.
I'm facing the same issue. Can you please let me knos if you have solved it and how? Actually I can see ttyGS0,1,2,3 in /dev/ but when connecting my USB to the pc I don't see any enumeration happening.
