Making the Drivers Load on Reboot
Although the drivers are loaded now, they won’t reload on reboot. To have them load automati-
cally each time the WL-HDD is rebooted, do the following to add the module names to the
/etc/modules file:
root@OpenWrt:~# echo “usbcore” >> /etc/modules
root@OpenWrt:~# echo “usb-ohci” >> /etc/modules
root@OpenWrt:~# echo “usbserial” >> /etc/modules
root@OpenWrt:~# echo “pl2303” >> /etc/modules

The order of the above lines is important. The usbcore driver must load before usb-ohci,
and so on.
