Hi All,
I could get to know from USB gadget drivers that, for setting USB
compositions we have to do in from user space.
>From ini.rc :
I saw :
# adb only USB configuration
# This should only be used during device bringup
# and as a fallback if the USB manager fails to set a standard
configuration
on property:sys.usb.config=adb
write /sys/class/android_usb/android0/enable 0
write /sys/class/android_usb/android0/idVendor 05C6
write /sys/class/android_usb/android0/idProduct 901D
write /sys/class/android_usb/android0/idProduct 61FC
write /sys/class/android_usb/android0/functions diag,adb
write /sys/class/android_usb/android0/enable 1
start adbd
setprop sys.usb.state $sys.usb.config
After booting this Qualcomm drivers will be bound.
My question is -
What are these things a) sys.usb.state
b) sys.usb.config
I found they are used in one shell script and in two java files but
could not follow it.
Please help me If any one knows ....
And how can I change the composition dynamically, if adb is not in the
composition.
Thanks
Prabhu
