User Manual

If your application uses USB storage devices or Compact Flash memory cards for additional storage, you must ensure that

these services do not start before these storage devices are properly mounted. You should therefore disable the automatic

startup of application(s) in question either by changing their startup state to off in WWW Setup at Setup Applications

or at shell prompt with command . The system startup script Default startup applications chkconfig application off

should then be edited ( ) according to the/etc/rc.d/rc.local WWW Setup Advanced settings System startup script

following example for :obexsender

#!/bin/sh

# This script will be executed *after* all the other init scripts.

# You can put your own initialization stuff in here you don'tif

# want to the full Sys V style init stuff.do

mkdir -p /mnt/disk

mount -t vfat /dev/sda1 /mnt/disk

[ $? != 0 ]; thenif

# run fsck.vfat only mounting failed, then to mountif try

again

fsck.vfat -a /dev/sda1

mount -t vfat /dev/sda1 /mnt/disk

# Script assumes you have disabled obexsender automatic startup as

instructed,

# so it is started now.

# Sleep is just to make sure filesystem is calm after mounting.

sleep 20

service obexsender start

6.2 Using USB sound cards

Access Devices features can be extended by adding external USB sound card. All devices providing generic

USB audio device class are supported. Please refer to see what devices we haveTested 3rd Party Peripherals

tested. Software currently supports only output.

USB sound card drivers are not installed by default. Those can be installed using software component

. If you like to have to play Ogg files, easiest way is to install thatkernel-modules-sound ogg123 oggplayerbundle

includes needed drivers, libraries and commands.

To use the USB sound card with Open Sound System (OSS) use command ( uses OSS):ogg123

[root@wrap /]$ modprobe snd-pcm-oss

If you compile your own application using Advanced Linux Sound Architecture (ALSA), there is no need to load OSS

emulation layer module.

Using is simple:ogg123

[root@wrap /]$ ogg123 file.ogg

Decoding high quality Ogg files real time is not possible in Access Devices.
