Introduction
Excerpt from USB/IP website: "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."
This page will give you all the informations to configure USB/IP to drive your APF/OPOS module from your Host USB devices.
Installation
- On your Host:
$ sudo apt-get install usbip
- On your APF/OPOS, everything should already be present in your rootfs if your use a post November 2017 BSP.
Usage
- On your Host, load USB/IP driver and launch usbipd daemon:
$ sudo modprobe usbip-host $ sudo usbipd -D
- then check which physical devices are attached to your Host and find which one you will share:
$ sudo usbip list -l - busid 3-1 (04d8:00df) Microchip Technology, Inc. : unknown product (04d8:00df) - busid 3-2 (093a:2510) Pixart Imaging, Inc. : Optical Mouse (093a:2510) - busid 3-3 (1c7a:0603) LighTuning Technology Inc. : unknown product (1c7a:0603) - busid 3-4 (8087:07dc) Intel Corp. : unknown product (8087:07dc)
- here I will share my USB mouse (3-2):
$ sudo usbip bind --busid 3-2 usbip: info: bind device on busid 3-2: complete
- On your APF/OPOS load the USB/IP virtual USB Host driver and ask the Host which devices are sharable (192.168.0.100 is the IP address of my Host PC on my local network):
# modprobe vhci-hcd
# usbip list --remote 192.168.0.100
usbip: error: failed to open /usr/share/hwdata//usb.ids

- test it ! ;-)
