usbip的目的是为了开发一个在局域网内共享的USB设备，也就是说你可以直接访问局域网内其他计算机的USB设备。在网上看到一篇如何安装usbip的文章，不过是英文，先转载保存，有时间再翻译下。
有关它的详细情况可参考其官方网站：http://usbip.sourceforge.net/

This tutorial shows how to set up a USB-over-IP server with Ubuntu 10.04 as well as a USB-over-IP client (also running Ubuntu 10.04). The USB/IP Project aims to develop a general USB device sharing system over IP network. To share USB devices between computers with their full functionality, USB/IP encapsulates "USB I/O messages" into TCP/IP payloads and transmits them between computers. USB-over-IP can be useful for virtual machines, for example, that don't have access to the host system's hardware - USB-over-IP allows virtual machines to use remote USB devices.
I do not issue any guarantee that this will work for you!
1 Preliminary Note
This tutorial is based on AliRezaTaleghani's tutorial How To Modify Your Gnu/Linux Box To Serve As A USB Over IP Server, but I've adjusted it for Ubuntu 10.04 (server and client). If you want to use a Windows client, please take a look at AliRezaTaleghani's tutorial - that part is still the same.
In this tutorial I use the server server1.example.com with the IP address 192.168.0.100 and the client client1.example.com with the IP address192.168.0.101, both running Ubuntu 10.04. These settings might differ for you, so you have to replace them where appropriate.
2 Installing And Using USB/IP On The Server
server1:
We can install usbip as follows:
aptitude install usbip
Afterwards we load the usbip kernel modules:
modprobe usbip
modprobe usbip_common_mod
To check if they really got loaded, run:
lsmod | grep usbip
The output should be similar to this one:
root@server1:~# lsmod | grep usbip
usbip 15124 0
usbip_common_mod 13605 1 usbip
root@server1:~#
To make sure that both modules get loaded automatically whenever you boot the system, you can add them to /etc/modules:
vi /etc/modules
[...] usbip usbip_common_mod |
Now we can start the usbip daemon:
usbipd -D
root@server1:~# usbipd -D
Bind usbip.ko to a usb device to be exportable!
root@server1:~#
Now attach a USB device that you want to export to the server - I'm using a SanDisk USB flash drive here.
Execute the command
lsusb
to find the corresponding Vendor/Device ID which is in the form of:
Bus XXX Device YYY: ID VendorID:DeviceID
The output on my server is as follows:
root@server1:~# lsusb
Bus 001 Device 002: ID 0781:5151 SanDisk Corp. Cruzer Micro Flash Drive
Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
root@server1:~#
The Vendor/Device ID of my SanDisk USB flash drive is 0781:5151.
Now run
usbip_bind_driver --list
The output on my server is as follows:
root@server1:~# usbip_bind_driver --list
List USB devices
- busid 1-1 (0781:5151)
1-1:1.0 -> usb-storage
root@server1:~#
As you see, the Vendor/Device ID of my SanDisk USB flash drive (0781:5151) corresponds to the BUSID 1-1. We need this BUSID to attach the USB device to the server:
usbip_bind_driver --usbip 1-1
root@server1:~# usbip_bind_driver --usbip 1-1
** (process:765): DEBUG: 1-1:1.0 -> usb-storage
** (process:765): DEBUG: unbinding interface
** (process:765): DEBUG: write "add 1-1" to /sys/bus/usb/drivers/usbip/match_busid
** Message: bind 1-1 to usbip, complete!
root@server1:~#
That's it, we can now use the SanDisk USB flash drive on a remote usbip client.
BTW, if you run...
netstat -tap
... you should see that the usbip daemon is listening on port 3240 so please make sure that this port isn't blocked by your firewall:
root@server1:~# netstat -tap
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 *:ssh *:* LISTEN 537/sshd
tcp 0 0 *:3240 *:* LISTEN 762/usbipd
tcp 0 52 server1.example.com:ssh 192.168.0.199:4024 ESTABLISHED 667/0
tcp6 0 0 [::]:ssh [::]:* LISTEN 537/sshd
root@server1:~#
3 Installing And Using USB/IP On The Client
client1:
We must install usbip on the client as well:
aptitude install usbip
Afterwards we load the vhci-hcd kernel module:
modprobe vhci-hcd
To check if it really got loaded, run:
lsmod | grep vhci_hcd
The output should be similar to this one:
root@client1:~# lsmod | grep vhci_hcd
vhci_hcd 19800 0
usbip_common_mod 13605 1 vhci_hcd
root@client1:~#
To make sure that the module gets loaded automatically whenever you boot the system, you can add it to /etc/modules:
vi /etc/modules
[...] vhci-hcd |
Now connect to the usbip server and get a list of available USB devices:
usbip -l 192.168.0.100
(192.168.0.100 is the IP address of the usbip server.)
You should find the SanDisk USB flash drive in the output (BUSID 1-1):
root@client1:~# usbip -l 192.168.0.100
- 192.168.0.100
1-1: SanDisk Corp. : Cruzer Micro Flash Drive (0781:5151)
: /sys/devices/pci0000:00/0000:00:07.2/usb1/1-1
: (Defined at Interface level) (00/00/00)
: 0 - Mass Storage / SCSI / Bulk (Zip) (08/06/50)
root@client1:~#
To attach that device to the client, run:
usbip -a 192.168.0.100 1-1
root@client1:~# usbip -a 192.168.0.100 1-1
8 ports available
port 0 attached
root@client1:~#
Now run...
lsusb
... and you should find the remote USB device in the output on the client:
root@client1:~# lsusb
Bus 001 Device 002: ID 0781:5151 SanDisk Corp. Cruzer Micro 256/512MB Flash Drive
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
root@client1:~#
You can now use the remote USB device as if it was a local USB device (e.g. mount it, format it, write to it, read form it, etc.).
4 Detaching A Remote USB Device
A remote USB device can be detached as follows:
client1:
Run...
usbip --port
... to find out the port that the remote USB device uses on the client - in this case it's port 00:
root@client1:~# usbip --port
8 ports available
Port 00: <Port in Use> at High Speed(480Mbps)
SanDisk Corp. : Cruzer Micro 256/512MB Flash Drive (0781:5151)
1-1 -> usbip://192.168.0.100:3240/1-1 (remote devid 00010002 (bus/dev 001/002))
1-1:1.0 used by usb-storage
/sys/class/bsg/1:0:0:0/device
/sys/class/scsi_device/1:0:0:0/device
/sys/class/scsi_disk/1:0:0:0/device
/sys/class/scsi_host/host1/device
/sys/class/usb_endpoint/usbdev1.4_ep02/device
/sys/class/usb_endpoint/usbdev1.4_ep81/device
/sys/block/sdb/device
Port 01: <Port Available>
Port 02: <Port Available>
Port 03: <Port Available>
Port 04: <Port Available>
Port 05: <Port Available>
Port 06: <Port Available>
Port 07: <Port Available>
root@client1:~#
We need the port number to detach the device:
usbip -d 00
root@client1:~# usbip -d 00
8 ports available
port 0 detached
root@client1:~#
On the server, we use the BUSID (1-1) to bind the USB device to the local system (the --other switch binds the device to the local system so that it is not available over the network anymore):
server1:
usbip_bind_driver --other 1-1
root@server1:~# usbip_bind_driver --other 1-1
** (process:7333): DEBUG: write "del 1-1" to /sys/bus/usb/drivers/usbip/match_busid
** Message: bind 1-1 to other drivers than usbip, complete!
root@server1:~#
Now go back to the client and check if the remote USB device is still available:
client1:
lsusb
If all goes well, it shouldn't be listed anymore:
root@client1:~# lsusb
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
root@client1:~#
