Linux hotplug setup for usblan

[irinoxx]

I've set up everything on my Mandriva box so that when I plug in my A780, the whole combo goes off to make telnet possible, and automatically mount the phone's samba shares.

Just in case anyone's interested, here are the files required :

/etc/hosts

Here you are, this is my basic setup. I hope that'll help.

As soon as possible, I'll add automatic backup / synchronization to this stuff. But first I have to locate where on the phone are stored the SMS, contact and agenda... If you have any suggestions, let me know.

Cool. I'll be trying it sometime before the weekend (so much to do, and so little time to do it...

Meanwhile, the biggest question (among many smaller ones that I will postpone until I try this) is: where do you get the file you called /usr/local/share/A780/usblan/usblan.o ?

Thanks again!

[evaldas]

Very good, thanks. I always hate scripting automatizations for hotplug/acpi by myself
sitaramc, 2.6.12 kernel has working usbnet.o included and use it instead of usblan.o. just "modprobe usbnet"

[irinoxx]

where do you get the file you called /usr/local/share/A780/usblan/usblan.o ?

Usblan module for kernel 2.4 found on Belcarra's website, which I compiled without any troubles.

[irinoxx]

2.6.12 kernel has working usbnet.o included and use it instead of usblan.o. just "modprobe usbnet"

Is that what you personally use? Cause I'd be glad to revert to a shiny 2.6 kernel if that usbnet module really works.

It only works with 2.6.12-rc* or later kernels (including final 2.6.12).

No thats wrong, with a little bit hand work you can get it running with other kernels too!

I have patched my 2.6.11-gentoo-r8 kernel and it works. You find patch at SourceForge.

I've just edited the first post of this thread to fix a few issues :

For some reason the hotplugging script got called multiple times in a row when I plugged my phone. I've made sure only one instance of the script can run at the same time.
I've added a monitoring script to automatically umount the samba shares when the phone is unplugged.
The scripts no longer try to play the pop sound if /dev/dsp is already in use (this bug froze the scripts)

(The modified files are sync_phone.sh, umount_phone.sh and the hotplug acm script)

Yes! it works!

You need to patch the drivers/usb/net/usbnet.c file with:
@@ -4071,6 +4071,9 @@
USB_DEVICE (0x8086, 0x07d3), // "blob" bootloader
.driver_info = (unsigned long) &blob_info,
}, {

+}, {

+ .driver_info = (unsigned long) &linuxdev_info,
+}, {

[for kernel 2.6.12, vanilla]

I have successfully telnet to e680 with that patch, and now I am trying to make it work with e680i. with 680i, The patch works, and I can see the the usb0 interfase when I plug the phone. The problem I am having is:

when I send
AT+MODE=99
to the phone (via minicom, for example)
a get:
ERROR
Any suggenstion?

Edited: found the solution:

the AT+MODE=99 thing was only for E680, not for E680i, for E680i you have to install linloader and make a script that says:
#!/bin/bash
echo MotNet > /proc/usbd-switch

did u find out where the SMS messages are stored on the system ?

thanks
