C3000 Usb Host: Auto Mount And Umount Usb Hdd Options

[DreamTheater]

I tested this with C3000 (ROM 1.01 JP). Use a USB mini-A cable to connect C3000 with your USB mass-storage device.

[Procedures]
1)

CODE

cd /mnt
mkdir usbhdd

2) Create a file /etc/hotplug/usb/usb-storage as follows. chmod it as 755.

CODE

#!/bin/sh
. /etc/hotplug/hotplug.functions
if [ ! -L /var/run/usb/%proc%bus%usb%* ]; then
 mesg Try to Mount
 mount /mnt/usbhdd
 if [ $? = 0 ]; then
   ln -s /etc/hotplug/usb/usb-storage.off $REMOVER
   mesg make REMOVER in $REMOVER
 fi
fi

3) Create a file /etc/hotplug/usb/usb-storage.off as follows. chmod it as 755.

CODE

#!/bin/sh
. /etc/hotplug/hotplug.functions
mesg Removing /mnt/usbhdd
umount /mnt/usbhdd
rmmod usb-storage

4) Add the following one line to /etc/fstab

CODE

/dev/sda1       /mnt/usbhdd     vfat    noauto,umask=000,noatime,iocharset=utf8,codepage=932    0  0

5) Connect your USB mass-storage device, you should be able to see it at /mnt/usbmem in a second you pluged the device. This is also visible from Sharp's qtopia GUI File manager.

I once tried my friend's 2.5inch bus-power type hard drive, but my C3000 couldn't power it. I am not sure how much current we can draw from C3000 USB host. It could be smaller than that of 6000, because C3000's USB host functionality is inside Intel PXA270 chip.
It looks like Archos bus-powered 1.8 inch hard drive is using Hitachi's drive which typically requires 200 - 300 mA, where typical 2.5 inch drive requires 500mA range.

The other option is to use MP3 player type hard drives or to use battery powered USB hub.
