[jancici]

network over USB is still not working

I have this configuration of kernel

flashed with OZ 3.5.3 from openzaurus.org + opie

Code: [Select]

uname -a
2.4.18-rmk7-pxa3-embedix

modprobe -l
not any output
what I have done
- configuring usbd0 on Z using graphical interface settins -> Network -> usbd0
I did used static ip, and switch on automatical bring up on boot
- I did restart Z
- I did configure usb0 on PC, set up with static IP

what is working
when I plug Z tu the gadget :
1. I can see it on PC, using lsub
2. usbd0 is UP on Z if it is not down

not working
on PC usb0 is not UP, I did check and find out that hotplug did not load module usbnet, this was working nicely with SharpROM

what is happening during pluging Z

try these http://gentoo-wiki.com/HOWTO_Synchronize_P...C_and_Evolution

[jancici]

well it saying that I will used serial connection between Z <> PC

but it was working with original SharpROM so I would like to get it working with usbnet, another people using that, so why I am not able to use that ?

EDIT:
okay, I did kompile new modules on PC for USB serial, this is new in my config

Code: [Select]

CONFIG_USB_SERIAL=m
CONFIG_USB_SERIAL_GENERIC=y
CONFIG_USB_SERIAL_IPAQ=m
so I did restart hotplug on PC, plug Z but nothing happend, still same problem

they are saying :

Code: [Select]

Connecting the PocketPC via USB should result in a log like

Feb  5 18:34:37 [kernel] usb 2-2: new full speed USB device using uhci_hcd and a ddress 4
 Feb  5 18:34:37 [kernel] ipaq 2-2:1.0: PocketPC PDA converter detected
 Feb  5 18:34:37 [kernel] usb 2-2: PocketPC PDA converter now attached to ttyUSB0but it is NOT happening on my PC

and on Z usbd0 is UP

[gfdsa]

CONFIG_USB_SERIAL_IPAQ=m
there should be option for zaurus
PocketPC PDA converter now attached to ttyUSB0 - means you are trying to use serial over USB, you need IP over USB

show /proc/bus/usb/devices

[jancici]

yes, I wolud like to IP over USB, but I did try that possibilities of serial over USB, but that is not working either.

you dont have usbnet driver loaded

[jancici]

well, I allready discusing this in getoo forum, seems that its bug in usbnet, but I am not sure, for me it is looks like bug in hotplug or I am something missing in hotplug

[Optogeek]

There does seem to be a bug in the 2.6.11 kernel.  It has caught a couple of us (other topic).  I have checked the changelog for 2.6.12.RC2 and there is passing mention of an usbnet problem with the Zaurus being fixed.  This was working in 2.6.10 fine.

[gfdsa]

jancici: if you would do 'modprobe usbnet' you would not need hotplug, just put config into your /etc/conf.d/net for iface_usb0 and ln -s net.lo net.usb0; /etc/init.d/net.usb0 restart

dunno about 2.6.11, im running 2.6.10

[jancici]

I did using IP over USB with original SharpROM without any problem, so I have already configured usb0 and symlink.

yes I did try to load that module but after that there is NOT usb0 device so there is a error during bringing usb0 UP

I think that HOTPLUG is doing something more that just loading modules
