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 is reported to be working, but we lack a HowTo yet!|
First install the usb kernel module and usbip server package:
opkg install kmod-usb-ohci usbip-server
Now using the usbip list -l list the local usb devices available that can be exported, in the following example an hub and usb printer is show:
root@OpenWrt:~# opkg install kmod-usb-ohci Installing kmod-usb-ohci (3.6.11-1) to root... Downloading http://test.ninux.org/~claudyus/brcm63xx/downloads.openwrt.org/snapshots/trunk/brcm63xx/packages//kmod-usb-ohci_3.6.11-1_brcm63xx.ipk. Configuring kmod-usb-ohci. root@OpenWrt:~# usbip list -l Local USB devices ================= - busid 2-1 (05e3:0608) 2-1:1.0 -> hub - busid 2-1.4 (04e8:344f) 2-1.4:1.0 -> unknown 2-1.4:1.1 -> unknown
The information that you are looking for is 2-1.4 that is the BUSID for the target device.
Edit the /etc/rc.local and before the 'exit 0' add the follow lines:
usbipd -D & sleep 1 usbip bind -b 2-1.4 # bind the busid
Using netstat you can see if everything works.
root@OpenWrt:~# netstat -alpt Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 0.0.0.0:3240 0.0.0.0:* LISTEN 927/usbipd
- #9953 (usbip server on OpenWRT fails after client tries to attach device) also features a small how to.
