Because of increasing interesting in USB over IP topic I decided to refresh my
old post.
I will focus on doing the same thing with more recent version of Raspabian.
If you need more information please read my previous post.
Setup SD card
First get recent version of
Raspbian, then unzip and dd
it to SD card:
1
|
sudo dd bs=4M if=2015-09-24-raspbian-jessie.img of=/dev/sdc
|
If you are impatient and want to know what happen in background you can use this
method of tracking dd progress:
1
|
sudo sh -c "while true; do killall -USR1 dd; sleep 1; done"
|
Before removing card we have to be sure that all data were wrote to card:
If this operation takes time you can watch progress work writeback and dirty
kilobytes using:
1
|
watch grep -e Dirty: -e Writeback: /proc/meminfo
|
When sync will finish you can remove SD card and sanity check booting on RPi.
Kernel for RPi
After booting you should be able to ssh to your RPi and check if USBIP was
compiled in your kernel.

pi@raspberrypi ~ $ sudo modprobe configs
pi@raspberrypi ~ $ zcat /proc/config.gz |grep USBIP
CONFIG_USBIP_CORE=m
CONFIG_USBIP_VHCI_HCD=m
CONFIG_USBIP_HOST=m
# CONFIG_USBIP_DEBUG is not set
|
Great! It looks like both server and client support was compiled as modules in
recent Raspbian.
Run server side of usbip
Unfortunately usbip user space tools are not available from scratch and have
to be installed:
1
|
sudo apt-get install usbip
|
Then you can run server:
1
2
3
|
pi@raspberrypi ~ $ sudo modprobe usbip-core
pi@raspberrypi ~ $ sudo modprobe usbip-host
pi@raspberrypi ~ $ sudo usbipd -D
|
Without connecting anything we get only internal Ethernet device when listing:
1

|
pi@raspberrypi ~ $ usbip list -l
- busid 1-1.1 (0424:ec00)
Standard Microsystems Corp. : SMSC9512/9514 Fast Ethernet Adapter (0424:ec00)
|
Let’s put some memory stick and check again:

|
pi@raspberrypi ~ $ usbip list -l
- busid 1-1.1 (0424:ec00)

- busid 1-1.2 (0951:1666)
Kingston Technology : unknown product (0951:1666)
|
Good usbip see our storage device. Let’s try to bind it:
1

3
|
pi@raspberrypi ~ $ sudo usbip --debug bind -b 1-1.2
usbip: debug: /build/linux-tools-06nnfo/linux-tools-3.16/drivers/staging/usbip/userspace/src/usbip.c:141:[run_command] running command: `bind'
usbip: info: bind device on busid 1-1.2: complete
|
Client side
Let’s check if device was correctly exposed by server on RPi. Of course we need
usbip package installed.

[13:28:50] pietrushnic:~ $ sudo usbip list -r 192.168.0.105
Exportable USB devices
======================
- 192.168.0.105

: (Defined at Interface level) (00/00/00)

Information is even more accurate then on RPi. Of course 192.168.0.105 have to
be replaced with you IP address.
Quickly check if client support correct modules:

[13:18:36] pietrushnic:~ $ grep USBIP /boot/config-`uname -r`
CONFIG_USBIP_CORE=m
CONFIG_USBIP_VHCI_HCD=m
CONFIG_USBIP_HOST=m
# CONFIG_USBIP_DEBUG is not set
|
Everything looks ok. Let’s load hos module:
Now we can attach remote storage:
1
|
sudo usbip attach -r 192.168.0.105 -b 1-1.3

[13:29:15] pietrushnic:~ $ sudo fdisk -l /dev/sdd
GPT PMBR size mismatch (13695 != 3911615) will be corrected by w(rite).

[13:29:39] pietrushnic:~ $ ls tmp

Let’s left some signs:

[13:30:55] pietrushnic:~ $ sudo sh -c "echo DEADBEEF > tmp/foobar"
[13:31:08] pietrushnic:~ $ cat tmp/foobar

Detach and see if we will see this file on server side:

[13:33:31] pietrushnic:~ $ sudo usbip port

-> remote bus/dev 001/005
[13:33:39] pietrushnic:~ $ sudo usbip detach -p 0

First let’s unbind:
1
2
|
pi@raspberrypi ~ $ sudo usbip unbind -b 1-1.3
usbip: info: unbind device on busid 1-1.3: complete
|
Then mount partition on which we placed out test file:

3
|
pi@raspberrypi ~ $ sudo mount /dev/sda1 tmp/
pi@raspberrypi ~ $ cat tmp/foobar
DEADBEEF

Summary
This is quick refresh for those struggling with running usbip. There many
topics to cover in this area I think about writing posts related to below
topics:
usbip on Raspberry Pi 2- passing frames for RS232 to USB converter using
usbip
- A20-OLinuXino-MICRO/Cubietruck and
usbip
If you any other preference or topics that would like to see on this blog please
let me know in comments. If you think this post can be useful for others please
share.
Thanks for reading.
