Because of the increasing interest in USB over IP topic, I decided to refresh my old post. I will focus on doing the same thing with the more recent version of Raspabian. If you need more information please read my previous post.
Setup SD card
First get the recent version of Raspbian, then unzip and dd it to SD card:
|
1 2 |
sudo dd bs=4M if=2015-09-24-raspbian-jessie.img of=/dev/sdc |
If you are impatient and want to know what happens in the background you can use this method of tracking dd progress:
|
1 2 |
sudo sh -c "while true; do killall -USR1 dd; sleep 1; done" |
Before removing card we have to be sure that all data were written to the card:
|
1 2 |
sync |
If this operation takes its time you can watch progress work writeback and dirty kilobytes using:
|
1 2 |
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.
|
1 2 3 4 5 6 7 |
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 userspace tools are not available from scratch and have
to be installed:
|
1 2 |
sudo apt-get install usbip |
Then you can run the server:
|
1 2 3 4 |
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 2 3 4 |
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:
|
1 2 3 4 5 6 7 |
pi@raspberrypi ~ $ usbip list -l - busid 1-1.1 (0424:ec00) Standard Microsystems Corp. : SMSC9512/9514 Fast Ethernet Adapter (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 2 3 4 |
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 the device was correctly exposed by the server on RPi. Of course, we need
usbip package installed.
|
1 2 3 4 5 6 7 8 |
[13:28:50] pietrushnic:~ $ sudo usbip list -r 192.168.0.105 Exportable USB devices ====================== - 192.168.0.105 1-1.3: Toshiba Corp. : TransMemory-Mini / Kingston DataTraveler 2.0 Stick (2GB) (0930:6544) : /sys/devices/platform/soc/20980000.usb/usb1/1-1/1-1.3 : (Defined at Interface level) (00/00/00) |
Information is even more accurate than on RPi. Of course, 192.168.0.105 have
to be replaced with your IP address.
Quickly check if client support correct modules:
|
1 2 3 4 5 6 |
[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:
|
1 2 |
sudo modprobe vhci-hcd |
Now we can attach remote storage:
|
1 2 |
sudo usbip attach -r 192.168.0.105 -b 1-1.3 |
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
[13:29:15] pietrushnic:~ $ sudo fdisk -l /dev/sdd GPT PMBR size mismatch (13695 != 3911615) will be corrected by w(rite).

Let’s left some signs:
|
1 2 3 4 |
[13:30:55] pietrushnic:~ $ sudo sh -c "echo DEADBEEF > tmp/foobar" [13:31:08] pietrushnic:~ $ cat tmp/foobar DEADBEEF |
Detach and see if we will see this file on server side:
|
1 2 3 4 5 6 7 8 9 |
[13:33:31] pietrushnic:~ $ sudo usbip port Imported USB devices ==================== Port 00: <Port in Use> at High Speed(480Mbps) unknown vendor : unknown product (0930:6544) 5-1 -> usbip://192.168.0.105:3240/1-1.3 -> remote bus/dev 001/005 [13:33:39] pietrushnic:~ $ sudo usbip detach -p 0 |
First let’s unbind:
|
1 2 3 |
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:
|
1 2 3 4 |
pi@raspberrypi ~ $ sudo mount /dev/sda1 tmp/ pi@raspberrypi ~ $ cat tmp/foobar DEADBEEF |
Summary
This is a quick refresh for those struggling with running usbip. There are many
topics to cover in this area I think about writing posts related to below
topics:
usbipon 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.
