<title>Configuring USB device access (Linux only)</title>

Linux is by default a multi-user system, so it has to have a policy to
|
||
|
|
determine who can access various devices. This includes those that can be
|
||
|
|
plugged into to a USB port.

For devices known to the operating system (which these days includes most
|
||
|
|
digital cameras, scanners, MIDI interfaces etc.), a logged-in user will be
|
||
|
|
granted access automatically. However, for devices that the OS doesn't
|
||
|
|
recognize (even if there is software on it that can use it), this is not the
|
||
|
|
case. It is possible to configure Linux to reverse this policy and grant all
|
||
|
|
users access to all devices, but this is not recommended for security
|
||
|
|
reasons.

<title>Configuring Access to a Frontier Design Tranzport</title>

<para>

|
Using the Tranzport on Linux requires a couple of extra steps to enable
|
||
|
|
non-administrative users to access the device.
|
||
|
|
</para>
|

|
|
|
||
|
|
<para>
|
||
|
|
First, you need to login as the administrative user ("root"). Then put the
|
||
|
|
following into a new file called <filename>/etc/hotplug/usb/tranzport</filename>
|
||
|
|
</para>
|
||
|
|
<screen>
|
||
|
|
#!/bin/sh
|
||
|
|
|
||
|
|
if [ $ACTION = "add" ] && [ -f $DEVICE ] ; then
|
||
|
|
chmod 0666 $DEVICE
|
||
|
|
fi
|
||
|
|
exit 0
|
||
|
|
</screen>
|
||
|
|
<para>
|
||
|
|
Then make sure that the file is executable by running
|
||
|
|
</para>
|
||
|
|
<screen>
|
||
|
|
chmod +x /etc/hotplug/usb/tranzport
|
||
|
|
</screen>
|
||
|
|
<para>
|
||
|
|
Second, edit the file <filename>/etc/hotplug/usb.usermap</filename> by adding the following 2
|
||
|
|
lines to the end of it (make sure that the 2nd line is not split across
|
||
|
|
multiple lines, even though it is very long):
|
||
|
|
</para>
|
||
|
|
<screen>
|
||
|
|
# Frontier Design Tranzport

||
|
|
tranzport 0x0000 0x165b 0x8101 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00 0x00 0x00000000
|
||
|
|
</screen>
|
||
|
|
<para>
|
||
|
|
After doing these steps, the next time you plugin your Tranzport it will be
|
||
|
|
accessible to you as a regular user.
