Red Hat Bugzilla – Bug 114149
doesn't find new eth1 device unless noted in modules.conf
Last modified: 2014-03-16 22:41:41 EDT
Description of problem:
kudzu doesn't recognize a new USB ADSL modem which installs itself as
ethx, unless its driver is noted in modules.conf.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install a new modem and driver which creates an ethernet device
2. Run system-config-network
3. Try to create a new xDSL connection.
See only the previously known Ethernet devices.
See the new device as well.
I'm using the German eagle-usb driver for the Allied Telesyn AT-AR215
(Analog Devices chipset) ADSL modem, available from
When this driver is loaded by hotplug, and the modem is correctly
initialized, a new device pops up under "ifconfig -a". I used to have
only eth0 (onboard Ethernet device), now there's also eth1 with the
correct MAC address.
Nevertheless, kudzu doesn't detect a new device, therefore
system-config-network doesn't allow me to use it for a new connection
I found a "workaround" by coincidence ("find /etc -type f | xargs
grep eth" ;->): If I add "alias eth1 eagle-usb" in modules.conf,
kudzu recognizes the device. (I need to fix the driver to eth1 now,
though.) Nevertheless, the driver works fine manually
(pppd/rp-pppoe/route) without this entry.
Is this perhaps necessary for kudzu/whatever to "query" eth1 in the
kernel? I realize that kudzu needs to know what is there, but I
really missed an instruction for this, because the actual driver
-> Documentation update?
-> Detection algorith update (also query /proc/bus/usb/)?
Does this persist in FC3 and later releases?
Sorry for the late answer - I needed to get around to setting up a new
installation to check for this (still running FC2 on the initial machine).
Yes, I still see this in FC3 + current updates. It's still exactly as described
in the original report. The interface eth1 is up, but s-c-n doesn't let me
Can you attach the output of 'lsusb -v'?
Created attachment 119247 [details]
Output from "lsusb -v"
This is from the machine from the original bug report. I assume you need the
info about the ADSL modem, and the rest may be irrelevant (like my old *cough*
kernel). I could provide output from the newly set up machine if it's of any
more value, but you'd need to give me a few days. ;-)
Apologies about the delay. We don't have this hardware in house. Does this
persist on F7 or similar? kudzu and system-config-network have changed
dramatically since then.
The information we've requested above is required in order
to review this problem report further and diagnose/fix the
issue if it is still present. Since there have not been any
updates to the report since thirty (30) days or more since we
requested additional information, we're assuming the problem
is either no longer present in the current Fedora release, or
that there is no longer any interest in tracking the problem.
Setting status to "INSUFFICIENT_DATA". If you still
experience this problem after updating to our latest Fedora
release and can provide the information previously requested,
please feel free to reopen the bug report.
Thank you in advance.
