Hello!
I've just tried the usb backport patch, as found at
http://www.suse.cz/development/usb-backport/, against the 2.2.15
kernel, just to see if I could make it work against my SMC EZ Connect
USB 2102USB/ETH ethernet converter.
The patch installed fine after that I had made some small changes to
it in order to avoid collision with the (previously applied) devfs
patch.
The changes done was:
- removed the adding of the "include/linux/devfs_fs_kernel.h" file
- commented out the following #define statements from the
"include/linux/kcomp.h" file:
TTY_DRIVER_NO_DEVFS
tty_register_devfs
tty_unregister_devfs
After that the compilation and installation of the modules went fine.
After reboot I noticed that "depmod -a" during boot did not included
any of the usb modules in the modules.dep file (all the usb code where
compiled as modules).
>From the information given at http://www.linux-usb.org/ I suspected that
the modules usbcore.o usb-uhci.o pegasus.o where the one that was most
likely to make the ethernet converter work.
First I installed the modules:
insmod /lib/modules/2.2.15/usb/usbcore.o
insmod /lib/modules/2.2.15/usb/usb-uhci.o
insmod /lib/modules/2.2.15/usb/pegasus.o
This gave the following messages in /var/log/messages:
... : usb.c: registered new driver usbdevfs
... : usb.c: registered new driver hub

... : pegasus.c: v0.3.9 2000/04/11 Written by Petko Manolov ([EMAIL PROTECTED])

Next I confimed that all the modules where loaded with lsmod
pegasus 5696 0 (unused)
usb-uhci 20952 0 (unused)
usbcore 39912 0 [pegasus usb-uhci]
Then I mounted the usbdevds filesystem with
mount -t usbdevfs none /proc/bus/usb
and got the following from /proc/bus/usb/devices

As the above shows, the usb subsystem seems to be able to make contact
with the converter, but in spite of that it does not shows up as a
network device (absent both from the "ifconfig -a" and "cat
/proc/net/dev" listings).
The "insmod" of the usb modules does not creates any new "devices"
under /dev either (note, controlled by devfs). I'm not sure if that
should happen?
Also if I try to remove the modules with rmmod I get the following
messages in /var/log/messages:
... : de_put: deferred delete of usb
... : usb.c: USB disconnect on device 1
... : usb.c: USB disconnect on device 2
... : usb.c: USB bus 1 deregistered

... : usb.c: deregistering driver pegasus
... : usb.c: deregistering driver usbdevfs
... : hub.c: usb_hub_thread exiting
... : usb.c: deregistering driver hub
The modules gets removed but I have to reboot again before trying to
install them again (insmod fails).
Has anyone any ideas to what I might try in order to make the
converter work or to find out more about where the problem are? The
(brief) documentation that I've found regarding the pegasus module
does not lists the above converter, but it lists a similar one.
Perhaps all that is needed is some small changes to the pegaus code
in order to make it detect the converter?
Or could it be that the packport patch does not works with the devfs
patch applied?
I'm totally new to the usb subsystem so any comments around this would
be most helpful.
best regards,
kmm
