Usb Networking, Does it work ? Options

[jeana]

Did somebody know how to activate the USB networking ?

[Capn_Fish]

CODE

modprobe usbnet
ifconfig usb0 up xxx.xxx.xxx.xxx

That's how it works normally, at any rate (under Angstrom/Debian, as well as other distros not on the Z).

Thank you for your reply Capn_Fish.

Unfortunately nothing happens when doing the modprobe and ifconfig :

• In dmesg nothing is logged
• ifconfig gives the error : usb0: ERROR while getting interface flags: No such device
  SIOCSIFADDR: No such device
  usb0: ERROR while getting interface flags: No such device
• lsusb list only the following : Bus 001 Device 001: ID 1d6b:0001
• When I connect or disconnect the USB cable nothing is logged in dmesg (if I put a mouse or an USB flash dmesg give me logs and the different device are recognized)

If I do a modprobe g_ether, I have the following with dmesg :

ether gadget: using random self ethernet address
ether gadget: using random host ethernet address
usb0: Ethernet Gadget, version: May Day 2005
usb0: using pxa27x_udc, OUT ep1out-bulk IN ep2in-bulk STATUS ep5in-int
usb0: MAC 46:8e:dc:59:4a:bf
usb0: HOST MAC 0e:1a:45:af:21:75
usb0: RNDIS ready
pxa2xx-udc pxa2xx-udc: UDC connecting

and lsusb gives the same result.

If I disconnect the USB cable, dmesg logs nothing.
If I reconnect the USB cable, dmesg logs :

pxa2xx-udc pxa2xx-udc: USB reset

Any idea ?

I have the following in /etc/network/interfaces

CODE

iface usb0 inet static
pre-up modprobe g_ether
address 192.168.129.201
netmask 255.255.255.0
broadcast 192.168.129.255
gateway 192.168.129.1
post-down rmmod g_ether

Try it out and see if it works for you.

Thank you for your help danr, but it doesn't work too.

In dmesg I get the following log after an ifup usb0 with the configuration given :

ether gadget: using random self ethernet address
ether gadget: using random host ethernet address
usb0: Ethernet Gadget, version: May Day 2005
usb0: using pxa27x_udc, OUT ep1out-bulk IN ep2in-bulk STATUS ep5in-int
usb0: MAC a2:14:42:31:43:b8
usb0: HOST MAC 8e:ca:e5:54:f2:eb
usb0: RNDIS ready
pxa2xx-udc pxa2xx-udc: UDC connecting
NET: Registered protocol family 10
ADDRCONF(NETDEV_UP): usb0: link is not ready

The USB cable is connected to a Windows XP Workstation.
When we plug or unplug the USB cable nothing is detected on the workstation USB devices !

Augh! I encountered that back when I was using gadget networking, but it's been 6 months and I've completely forgotten how I fixed it!

Actually - did you ifup usb0 before or after plugging the cable in? I seem to recall it never worked properly unless I started it with the cable disconnected on the zaurus end.

Thank you pelrun for you experience.

I tried with and without the USB cable plugged to launch ifup usb0 without success (I launched a reboot after each operation to be sure that the system is in the same state)

g_ether also not work for me.
I am using sl-c1000

Did somebody know how to activate the USB networking ?

FWIW: Whenever I plug in my usb ethernet adapter I have to run this code:

CODE

echo -n 1 >/sys/bus/usb/devices/1-2/bConfigurationValue

Some recent advance in the system development sets a lower power cutoff threshold that my adapter doesn't meet. Thus the workaround. I've never crashed using this workaround. It has been covered in the forums.
