KERNEL CONFIGURATION

To enable all modules, that are required for work of usbip tool, call:

make linux-menuconfig

Then find next options and press M to enable them as a module:

CONFIG_USBIP_CORE=m
CONFIG_USBIP_VHCI_HCD=m
CONFIG_USBIP_VHCI_HC_PORTS=8
CONFIG_USBIP_VHCI_NR_HCS=1
CONFIG_USBIP_HOST=m
CONFIG_USBIP_VUDC=m
CONFIG_USB_GADGET=y

Run make to build everything.

make

START USBIP-SERVER ON HSDK

Load usbip modules:

modprobe usbip-core
modprobe usbip-host
modprobe vhci-hcd

To check if everything is working right, run:

lsmod | grep usbip

Run usbip server:

usbipd -D

To get Bus ID of USB device, that will be shared, run:

usbip list -l

Output example:

# usbip list -l
 - busid 1-1.1 (3538:0058)
   Power Quotient International Co., Ltd : unknown product (3538:0058)

To share USB device run:

usbip bind --busid=<busid>

Output example:

# usbip bind --busid=1-1.1
usbip-host 1-1.1: usbip-host: register new device (bus 1 dev 4)
usbip: info: bind device on busid 1-1.1: complete

Now server is ready for work! To check if device is exportable, run:

usbip list -r localhost

Output example:

Exportable USB devices
======================
 - localhost
      1-1.1: Power Quotient International Co., Ltd : unknown product (3538:0058)
           : /sys/devices/platform/soc/f0040000.ehci/usb1/1-1/1-1.1
           : (Defined at Interface level) (00/00/00)

Client setup

Run usbip server:

usbipd -D

To attach to shared device run:

sudo usbip attach --remote=<remote_ip> --busid=<busid>
