71[Example]
72---------------------------
73	SERVER SIDE
74---------------------------
75Physically attach your USB devices to this host.
76
77    trois:# insmod path/to/usbip-core.ko
78    trois:# insmod path/to/usbip-host.ko
79    trois:# usbipd -D
80
81In another terminal, let's look up what USB devices are physically
82attached to this host.
83
84    trois:# usbip list -l
85    Local USB devices
86    =================
87     - busid 1-1 (05a9:a511)
88	     1-1:1.0 -> ov511
89
90     - busid 3-2 (0711:0902)
91	     3-2:1.0 -> none
92
93     - busid 3-3.1 (08bb:2702)
94	     3-3.1:1.0 -> snd-usb-audio
95	     3-3.1:1.1 -> snd-usb-audio
96
97     - busid 3-3.2 (04bb:0206)
98	     3-3.2:1.0 -> usb-storage
99
100     - busid 3-3 (0409:0058)
101	     3-3:1.0 -> hub
102
103     - busid 4-1 (046d:08b2)
104	     4-1:1.0 -> none
105	     4-1:1.1 -> none
106	     4-1:1.2 -> none
107
108     - busid 5-2 (058f:9254)
109	     5-2:1.0 -> hub
110
111A USB storage device of busid 3-3.2 is now bound to the usb-storage
112driver. To export this device, we first mark the device as
113"exportable"; the device is bound to the usbip-host driver. Please
114remember you can not export a USB hub.
115
116Mark the device of busid 3-3.2 as exportable:
117
118    trois:# usbip --debug bind --busid 3-3.2
119    ...
120    usbip debug: usbip_bind.c:162:[unbind_other] 3-3.2:1.0 -> usb-storage
121    ...
122    bind device on busid 3-3.2: complete
123
124    trois:# usbip list -l
125    Local USB devices
126    =================
127    ...
128
129     - busid 3-3.2 (04bb:0206)
130	     3-3.2:1.0 -> usbip-host
131    ...
132
133---------------------------
134	CLIENT SIDE
135---------------------------
136First, let's list available remote devices that are marked as
137exportable on the host.

190[Checklist]
191    - See 'Debug Tips' on the project wiki.
192	- http://usbip.wiki.sourceforge.net/how-to-debug-usbip
193    - usbip-host.ko must be bound to the target device.
194	- See /proc/bus/usb/devices and find "Driver=..." lines of the device.
195    - Shutdown firewall.
196	- usbip now uses TCP port 3240.
197    - Disable SELinux.
198    - Check the kernel and daemon messages.
