81 | <para>libusb requires the usbfs kernel filesystem to be mounted on
|

82 | <filename class="directory">/proc/bus/usb</filename>. Applications require the
|
---|
83 | files in this directory to be accessible to the user, sometimes for both
|
---|
84 | reading and writing. To restrict access to <acronym>USB</acronym> devices,
|
---|
85 | ensure the usb group exits on your system. If necessary, create the usb group
|
---|
86 | using the following command:</para>
|

87 |

88 | <screen><userinput><command>groupadd -g 14 usb</command></userinput></screen>

91 | not recommended. However, if you did compile it as a module, you can install an

92 | init script to mount usbfs at system boot-up. An init script is included in the
