  71 [Example]
  72 ---------------------------
  73         SERVER SIDE
  74 ---------------------------
  75 Physically 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
  81 In another terminal, let's look up what USB devices are physically
  82 attached 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
 111 A USB storage device of busid 3-3.2 is now bound to the usb-storage
 112 driver. To export this device, we first mark the device as
 113 "exportable"; the device is bound to the usbip-host driver. Please
 114 remember you can not export a USB hub.
 115
 116 Mark 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 ---------------------------
 136 First, let's list available remote devices that are marked as
 137 exportable 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.
