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.

Thanks a lot for the help and links. Evidently, the partition the iPod actually uses for data is partition 2. In turn, via telnet:

CODE

bash-2.05# /sbin/lsmod

bash-2.05# mount -t vfat -o umask=000,noatime,iocharset=utf8,codepage=932 /dev/sda2 /mnt/usbstorage

Everything works fine. Thanks again. Now I can use it as a portable video player...
