USB mouse not working with Android jb4.2.2_1.0.0 BSP on SABRE SDB

[llatvala]

I'm setting up Sabre SDB imx6q board. Just got Android jb4.2.2_1.0.0 BSP demo image successfully installed and adjusted u-boot configuration according to the instructions.

Now there is still a problem with USB. I’m trying to connect a mouse into USB-OTG adapter.

I tried to connect directly and via powered usb hub, but there’s no response.

I've attached the boot log and there are some lines stating that USB is disabled: android_usb: already disabled

Any idea why and what to do to get USB working?

Note :USB OTG port of the SDB with special cable (USB_ID grounded) should used

to connect a USB device. The second USB connector of the SDP is used as console

(USB-to-UART).

I created the following adapter which grounds the USB ID pin, and verified the connections with multimeter.

1 ---  Red   --- 1 (VBUS)

2 --- White --- 2 (D-)

3 --- Green --- 3 (D+)

4 --- Black --- 4 (ID)

5             \--- 5 (GND)

Didn't work for me. USB mouse is still not recognized during boot. The boot log is identical to the previously attached one.

Any idea why Android USB would be disabled during boot, as these messages would suggest: android_usb: already disabled

Are you trying the android_jb4.2.2_1.0.0-ga prebuilt image? When a USB mouse is plugged to the OTG port, you should see the following messages:

root@android:/ # ID int (ID is 0)

Please plug in the USB mouse before the android request suspend state. In this prebuilt image, USB device connection (such as USB mouse) does not wake up the board.
