Howto Configure A Usb Ethernet Adaptor

[desertrat]

Yup i am using the host cable and i can use it for other stuff, and the nic powers up.  I just dont get any messages in dmesg.  Maybe I will try to reflash and see if that makes a difference.

OK just to be absolutely clear, by dmesg I mean the command dmesg & its output and not the contents of /var/log/dmesg (which, AFAICT, never changes after bootup).

Now i feel even more silly.  Your right i was looking in the logs.  Here is the output of the dmesg:

hub.c: USB new device connect on bus1/1, assigned device number 15
usb.c: USB device 15 (vend/prod 0x846/0x1040) is not claimed by any active driver.
usb.c: USB disconnect on device 15
pegasus.c: v0.4.22 (2001/12/07):Pegasus/Pegasus II USB Ethernet driver
usb.c: registered new driver pegasus
hub.c: USB new device connect on bus1/1, assigned device number 16
usb.c: USB device 16 (vend/prod 0x846/0x1040) is not claimed by any active driver.

It sees the device but does not see a driver for it.

What does lsmod show? Is the module pegasus listed? If not try, loading the module manually using modprobe pegasus. If that fails, does the file /lib/modules/2.4.20/kernel/drivers/usb/pegasus.o exists?

What does ifconfig -a show?

/lib/modules/2.4.20/kernel/drivers/usb/pegasus.o does not seem to be there, i guess that would do it.

I believe that file is provided by the package kernel-modules.

When you say "worked out of the box", do you mean to say that you didn't have to fiddle about with any of the hotplug scripts etc? What does your adaptor appear as, eth0 or something else?

Just connected the adaptor. No fiddling with hotplug. It just appears as eth0 and works fine.

kernel-modules package did not give it to me.  Im going to just start installing stuff and I will report back if i find it.

Thanks

the kernel-module package kills my built in wifi  so i have to reflash to a backup.  Cant find the pegasus.o file anyplace.

Could you explain how it works? In rc12 through to beta3, if I don't make any of the changes as described at the start of this thread then when I plug in my adaptor nothing happens - ie dhcpcd doesn't get run and hence eth0 doesn't get initialised:

Code: [Select]

I had a look at the feeds for the various models of Zs. The 3100 feed only has 1 kernel-modules package and it weighs in at 1.6MB, whereas the feeds for the other models (including 6000) has a small kernel-modules package (~600KB) plus several kernel-modules-* packages. So my guess is that only the 3xxx feeds will have the pegasus module (plus it has loads more modules that the older models' feeds don't have).

Oh, and don't even think of using the 3xxx package because they're for the 2.4.20 kernel whereas the other models use a 2.4.18 kernel

Hi trichmon

I compiled the pegasus module for the tosa kernel - no idea whether it works because I don't have this adapter, but it's worth a go. It's not an IPK (forum filters); you'll have to rename it to 'pegasus.o'.

(disclaimer: all care, no responsibility  )

Thanks for the try karlto.  But even if i modprobe it and then hookup the nic I get nothing in ifconfig -a (other than the loopback).   I also just tried with a hawkins huf11 that is known to work on the sharp rom ( i think its a realteck chipset) with the same results.  I guess that each machine (tosa, akita, etc) has a hit or miss chance of using these out of the box.  

Im starting to feel odd man out again with my tosa. Do you happen to use a usb ethernet adaptor (ill buy what ever if know that it works).

I just use the USB cable to my laptop via the cradle, or wireless, so I have no idea what works. None of the USB ethernet drivers are enabled in the default kernel config though; thats probably why the huf11 doesn't work either...  

I think perhaps that I have missed something with the kernel config for USB - all I changed was adding the pegasus module. It compiled OK, but could be something else required to actually support USB network adapters in general. Can anyone post the kernel USB options for a working implementation?

I presume the module actually loaded successfully? You didn't put it under 2.4.20 as above did you? (Is '/lib/modules/2.4.18-rmk7-pxa3-embedix/kernel/drivers/usb/' on my tosa). Any dmesg output from loading the module? Surely you should plug in the NIC before modprobing the module (most drivers won't load if the hardware isn't present).

I'm sure it can be made to work with not too much hassle (just getting the right driver modules). Not sure why a lot of this stuff is not compiled by default for the SL6000 - probably lack of test equipment.

I did put the pegasus.o file in the same place on my tosa as you listed.  Below is the dmesg output that talks about this device.  It seems to see it and says the driver is loaded.  I dont get anything with ifconfig -a .


dmesg output:

Hmm.... well, the drive loads OK, but doesn't actually locate the hardware. Did you try to rmmod the acm module (not sure why it loaded that) before modprobing the pegasus module? Maybe it is blocking it?
