8 <title>Configuring USB device access (Linux only)</title>
10 Linux is by default a multi-user system, so it has to have a policy to
11 determine who can access various devices. This includes those that can
12 be plugged into to a USB port.
16 For devices known to the operating system (which these days includes
17 most digital cameras, scanners, MIDI interfaces etc.), a logged-in user
18 will be granted access automatically. However, for devices that the OS
19 doesn't recognize (even if there is software on it that can use it),
20 this is not the case. It is possible to configure Linux to reverse this
21 policy and grant all users access to all devices, but this is not
22 recommended for security reasons.

26 <title>Configuring Access to a Frontier Design Tranzport</title>
28 Using the Tranzport on Linux requires a couple of extra steps to
29 enable non-administrative users to access the device.
33 First, you need to login as the administrative user ("root"). Then put
34 the following into a new file called
35 <filename>/etc/hotplug/usb/tranzport</filename>
40 if [ $ACTION = "add" ] && [ -f $DEVICE ] ; then
46 Then make sure that the file is executable by running
49 chmod +x /etc/hotplug/usb/tranzport
52 Second, edit the file <filename>/etc/hotplug/usb.usermap</filename> by
53 adding the following 2 lines to the end of it (make sure that the 2nd
54 line is not split across multiple lines, even though it is very long):
57 # Frontier Design Tranzport
58 tranzport 0x0000 0x165b 0x8101 0x0000 0x0000 0x00 0x00 0x00 0x00 0x00 0x00 0x00000000
61 After doing these steps, the next time you plugin your Tranzport it
62 will be accessible to you as a regular user.
