[Requirements]
- USB/IP device drivers
Its source code is included under $(top)/drivers/.

- sysfsutils >= 2.0.0
sysfsutils library

- libwrap0-dev
tcp wrapper library

- gcc >= 4.0

- libglib2.0-dev >= 2.6.0

- libtool, automake >= 1.9, autoconf >= 2.5.0, pkg-config

[Install]
0. Skip here if you see a configure script.
$ ./autogen.sh

1. Compile & install.
$ ./configure
$ make install

2. Compile & install USB/IP drivers if not yet.

[Usage]
server:# (Attach your USB device physically.)

server:# insmod usbip-core.ko
server:# insmod usbip-host.ko
- It was formerly named as stub.ko.

server:# usbipd -D
- Start usbip daemon.

server:# usbip_bind_driver --list
- List driver assignments for usb devices.

server:# usbip_bind_driver --usbip 1-2
- Bind usbip-host.ko to the device of busid 1-2.
- A usb device 1-2 is now exportable to other hosts!
- Use 'usbip_bind_driver --other 1-2' when you want to shutdown exporting
and use the device locally.


client:# insmod usbip-core.ko
client:# insmod vhci-hcd.ko
- It was formerly named as vhci.ko.

client:# usbip --list server
- List exportable usb devices on the server.

client:# usbip --attach server 1-2
- Connect the remote USB device.

client:# usbip --port
- Show virtual port status.

client:# usbip --detach 0
- Detach the usb device.


[Output Example]
--------------------------------------------------------------------------------------------------------
- SERVER SIDE (physically attach your USB devices to this host) ----------------------------------------
--------------------------------------------------------------------------------------------------------
trois:# insmod (somewhere)/usbip-core.ko
trois:# insmod (somewhere)/usbip-host.ko
trois:# usbipd -D

--------------------------------------------------------------------------------------------------------
In another terminal, let's look up what usb devices are physically attached to
this host. We can see a usb storage device of busid 3-3.2 is now bound to
usb-storage driver. To export this device, we first mark the device as
"exportable"; the device is bound to usbip driver. Please remember you can not
export a usb hub.

trois:# usbip_bind_driver --list
List USB devices
- busid 3-3.2 (04bb:0206)
3-3.2:1.0 -> usb-storage

- busid 3-3.1 (08bb:2702)
3-3.1:1.0 -> snd-usb-audio
3-3.1:1.1 -> snd-usb-audio

- busid 3-3 (0409:0058)
3-3:1.0 -> hub

- busid 3-2 (0711:0902)
3-2:1.0 -> none

- busid 1-1 (05a9:a511)
1-1:1.0 -> ov511

- busid 4-1 (046d:08b2)
4-1:1.0 -> none
4-1:1.1 -> none
4-1:1.2 -> none

- busid 5-2 (058f:9254)
5-2:1.0 -> hub

--------------------------------------------------------------------------------------------------------
Mark the device of busid 3-3.2 as exportable.

trois:# usbip_bind_driver --usbip 3-3.2
** (process:24621): DEBUG: 3-3.2:1.0 -> none
** (process:24621): DEBUG: write "add 3-3.2" to /sys/bus/usb/drivers/usbip/match_busid
** Message: bind 3-3.2 to usbip, complete!

trois:# usbip_bind_driver --list
List USB devices
- busid 3-3.2 (04bb:0206)
3-3.2:1.0 -> usbip
(snip)

Iterate the above operation for other devices if you like.


--------------------------------------------------------------------------------------------------------
- CLIENT SIDE ------------------------------------------------------------------------------------------
--------------------------------------------------------------------------------------------------------
First, let's list available remote devices which are marked as exportable in
the server host.

[Check List]
- See Debug Tips in the project wiki.
- http://usbip.wiki.sourceforge.net/how-to-debug-usbip
- usbip-host.ko must be bound to the target device.
- See /proc/bus/usb/devices and find "Driver=..." lines of the device.
- Shutdown firewall.
- usbip now uses TCP port 3240.
- Disable SELinux.
- If possible, compile your kernel with CONFIG_USB_DEBUG flag and try
again.
- Check your kernel and daemon messages.
ex. /var/log/{messages, kern.log, daemon.log, syslog}
