No write permission for all usb in /dev/bus/usb/xxx

[GoogleCodeExporter]

What steps will reproduce the problem?
I ahve build Gingerbread (Android 2.3) for xm beagle board. I need write 
permission for all the usb port at the time of booting itself. For that i have 
added the statement 

mount -t usbfs none /proc/bus/usb/ -o devmode=0666

It works and usbfs is mounted in /proc/bus/usb/ with write permission. 

What is the expected output? What do you see instead?
 I need write permission in /dev/bus/usb/ also.

$ls -l /dev/bus/usb/001/

crw-rw-rw- root     usb      189,  10 1970-01-02 00:02 011

crw-rw-rw- root     usb      189,   4 1970-01-01 00:00 005  

but it is seen as,

crw-rw---- root     usb      189,  10 1970-01-02 00:02 011

You probably have to make entries in init.rc to obtain permissions in /dev.
See the existing entries in init.rc for reference
