kmod-usb-bcma is not available

[Nerijus Baliūnas]

Just FYI - no, bcma-hcd was not needed, /etc/init.d/gtm382 was enough for 
lsusb to see modem:

#!/bin/sh /etc/rc.common

START=11

cd /sys/class/gpio
echo 4 > export
echo 5 > export

cd
echo out > /sys/class/gpio/gpio4/direction
echo 1 > /sys/class/gpio/gpio4/value
echo out > /sys/class/gpio/gpio7/direction
echo out > /sys/class/gpio/gpio4/direction
echo 1 > /sys/class/gpio/gpio4/value
echo out > /sys/class/gpio/gpio5/direction
echo 1 > /sys/class/gpio/gpio5/value
