How can i use acm and adb ?

[jamesbone]

Hi,    add the following lines in init.freescale.usb.rc

on property:sys.usb.config=mtp,adb,acm

    write /sys/class/android_usb/android0/enable 0

    write /sys/class/android_usb/android0/idVendor 18d1

    write /sys/class/android_usb/android0/idProduct d02

    write /sys/class/android_usb/android0/functions $sys.usb.config

    write /sys/class/android_usb/android0/f_acm/instances 1

    write /sys/class/android_usb/android0/enable 1

    start adbd

    setprop sys.usb.state $sys.usb.config

along with this it needs one more line in

default.prop  i.e   change persist.sys.usb.config=mtp,adb   to  persist.sys.usb.config=mtp,adb,acm  it will work.

Have a great day,
Jaime
