IMx6 Android 4.2 BSP: g_audio enabling for USB host interface

manju_g — Mon, 02 Mar 2020 09:11:57 GMT

Hi Support,

I need your support in configuring the USB audio for HOST interface ‘0’.

I enabled currently USB Audio:

1014: [0] <2020-03-02> <12:15:30.686> 3 [MS ]: USB-Audio - Jabra UC VOICE 550a MS

1015: [0] <2020-03-02> <12:15:30.687> Jabra Jabra UC VOICE 550a MS at usb-fsl-ehci.1-1, full speed

Actually it is enabled for “usb-fsl-ehci.1-1”. I need to enable for “fsl-ehci.0”

Can you please provide the change points where we can enable the host “fsl-ehci.0”.

Below are the 2 USB interfaces which are enabled in our board.
